Pulmonary arterial hypertension in repaired congenital heart disease: a multicentre study
Creators: name: Constantine, Andrew
Publisher: name: Imperial College London
Year: 2023

description: This doctoral thesis aims to investigate the demographics, treatment patterns and prognosis of paediatric pulmonary hypertension (PH) and the emerging group of children and adults with PH in the setting of repaired congenital heart disease (CHD). I have conducted three studies, each with a distinct focus. The first is a retrospective, longitudinal study of ten CHD centres across the UK that assesses the clinical characteristics and treatment patterns of adults with a Fontan-type circulation receiving pulmonary vasodilators. I have compared treated patients with a matched cohort of Fontan patients who are not receiving pulmonary vasodilator therapy, complemented by an expert survey to determine current practice and the goals of therapy. In the second study, I created a 20-year national UK registry of paediatric PH and derived estimates of incidence and prevalence for all groups of paediatric PH in different age categories. I determined the natural history of paediatric PH and performed survival analysis. I then focused on patients with CHD and described the changes in demographics, with a substantial increase in patients with previously repaired CHD, who now form the largest PAH-CHD subgroup. The third study focuses on this latter group of repaired PAH-CHD. I highlighted the heterogeneity in terms of severity and onset of PAH. I identified prognostic markers and variables associated with PH resolution and developed a novel risk score for predicting adverse clinical outcomes in this group. This score will form the basis for the risk stratification of this high-risk population, to inform prognostication and guide treatment.

A Paper-Based Transwell Assay to Study Cancer-Cell Invasion in 3D
Creators: name: Loeser, Adam
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Cellular invasion is the gateway to metastasis, the leading cause of cancer-related deaths today. Therefore, in the fight against cancer, it is crucial to better understand the cues and conditions under which cellular invasion occurs. Such an understanding has the potential to lead to therapeutic treatments capable of halting a tumor in its progression towards a metastatic state. A popular current method of studying invasion is the modified Transwell assay, comprised of two chambers separated by a matrix-coated membrane through which cells can migrate in response to various chemokines. Although Transwell assays are readily available, customizable and provide easily interpretable data, they are expensive and offer little flexibility in assay setup. Here, we present a paper-based variation of the Transwell assay capable of generating similar datasets with equal reproducibility to the traditional setup at a fraction of the cost.

description: Intermediate surface brightness (ISB) galaxies are less numerous than their counterparts at high and low surface brightness (HSB and LSB). Investigating ISB characteristics from a sample from the S4G survey, complete down to M_B=-16, we find that they have intermediate stellar, gas and baryonic masses and on average as much gas as stars. They lie on the (baryonic) Tully-Fisher relation between HSBs and LSBs, although they present a higher scatter than the latter. Their stellar to baryonic mass ratios have intermediate values unlike their condensed baryonic fractions. By comparing their environments, as classified by the eigenvalues of the velocity shear tensor of local constrained simulations, ISBs have a 5-10% probability higher (smaller) to be in sheets (filaments) with respect to HSBs and LSBs. Additionally, for galaxies in filaments (with close neighbors), the mass and mu_0 are correlated at 2.5 (2) sigma more than for those in sheets. ISBs live in regions where the divergence of the velocity field is smaller than where HSBs and LSBs live, a result at more than 50% significance. ISBs may exist as an unstable transition state between LSBs and HSBs, the low flow activity environment maximally encouraging their formation. Interaction events altering the central baryon fraction could happen at a lower rate in these less dense environment, whilst in the higher density environments the LSBs are primarily satellite galaxies, whose accretion is sufficiently constrained that it fails to promote them to HSBs.

Biofidelic simulations of embryonic joint growth and morphogenesis
Creators: name: Godivier, Josépha
Publisher: name: Imperial College London
Year: 2022

description: During skeletal development, the opposing surfaces in the joint mould into interlocking and reciprocal shapes in a process called morphogenesis. Morphogenesis is critical to the health and function of the joint, and yet, little is known about the process of joint morphogenesis. For example, how do different joints acquire their specific shapes? Which cellular processes underlie joint shaping and how are they regulated? However, it is known that fetal movements are critical to joint development, with alterations or absences of movement being implicated in multiple pre- and post-natal musculoskeletal conditions. This doctorate explored the cell-level dynamics governing joint growth and the implication of movements in regulating them, using novel biofidelic and mechanobiological models of joint growth. Cell-level data from wild type zebrafish larvae were tracked and synthesised in a biofidelic simulation of zebrafish jaw joint growth. Growth characteristics were quantified revealing a strong anisotropy (Chapter 3). Next, zebrafish larvae were immobilised using drug treatment. The material properties of the zebrafish jaw cartilage were measured using nano-indentation in the presence or absence of movement showing a delay in cartilage stiffening in immobilised larvae (Chapter 4). Then, I developed a novel mechanobiological model of zebrafish jaw joint growth, which identified a correlation between growth characteristics and the dynamic patterns of mechanical stimuli experienced by joint elements over jaw motion (Chapter 5). Finally, local growth rates were characterised in the mouse elbow in the presence or absence of skeletal muscles. Spatial heterogeneity in the growth rates correlated with the emergence of specific shape features at the level of the condyles. Immobilisation led to disruption of the local growth rates correlated with failed shape differentiation of the condyles. The relative contribution of key cell activities to growth such as cell volume expansion, cell number increases and extracellular matrix expansion, were shown to vary over time in both wild types and muscleless-limbs and to be altered in the absence of skeletal muscles (Chapter 6). This research offers avenues for improvement in simulations of joint development and potentially other organs. It provides fundamental advance in our understanding of mechanoregulation in the developing joint and increases our understanding of the origins of musculoskeletal abnormalities.

From Obama to Trump: White Status Anxiety in the 2016 Presidential Election
Creators: name: Buxton, Emily Drake
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: This honors thesis examines the underlying causes that led to the shift in electoral support from Barack Obama to Donald Trump. White status anxiety led to an increase of voters in the white working class, the demographic primarily responsible for the election of Donald Trump. By studying the question of what led to the polarizing presidential election of Trump, this thesis contributes to knowledge of underlying policy tensiosn in America. This diagnosis will lead to better policy that addresses underlying tensions racial status and gender status. I use two main approaches to address this topic: 1) historical research and contextualization and 2) case studies of three counties that switched from voting from Obama in 2008 and 2012 to Trump in 2016. I conducted qualitative interviews with public officials in each county to understand context and attitudes from 2000 to 2016. I find that while each county’s economy remained stable during the 2008-2016 time period, each county experienced changing demographics and, among white citizens, a perception of a declining status relative to other racial or ethnic groups. This racial status anxiety was born from centuries of policies that have structurally embedded racial dynamics in American society and were directly addressed by Trump in the 2016 election. This finding has implications in policy as it points to the need to more explicitly address race and racial equity as underlying and pervasive components of American culture, as well as the need to understand the long-term consequences of policy decisions in psychological and cultural patterns.

description: In graphene spintronics, interaction of localized magnetic moments with the electron spins paves a new way to explore the underlying spin relaxation mechanism. A self-assembled layer of organic cobalt-porphyrin (CoPP) molecules on graphene provides a desired platform for such studies via the magnetic moments of porphyrin-bound cobalt atoms. In this work a study of spin transport properties of graphene spin-valve devices functionalized with such CoPP molecules as a function of temperature via non-local spin-valve and Hanle spin precession measurements is reported. For the functionalized (molecular) devices, we observe a slight decrease in the spin relaxation time (τs), which could be an indication of enhanced spin-flip scattering of the electron spins in graphene in the presence of the molecular magnetic moments. The effect of the molecular layer is masked for low quality samples (low mobility), possibly due to dominance of Elliot-Yafet (EY) type spin relaxation mechanisms.

Interfacial thermal conduction and negative temperature jump in one-dimensional lattices

description: We study the thermal boundary conduction in one-dimensional harmonic and $ϕ^{4}$ lattices, both of which consist of two segments coupled by a harmonic interaction. For the ballistic interfacial heat transport through the harmonic lattice, we use both theoretical calculation and molecular dynamics simulation to study the heat flux and temperature jump at the interface as to gain insights of the Kapitza resistance at the atomic scale. In the weak coupling regime, the heat current is proportional to the square of the coupling strength for the harmonic model as well as anharmonic models. Interestingly, there exists a negative temperature jump between the interfacial particles in particular parameter regimes. A nonlinear response of the boundary temperature jump to the externally applied temperature difference in the $ϕ^{4}$ lattice is observed. To understand the anomalous result, we then extend our studies to a model in which the interface is represented by a relatively small segment with gradually changing spring constants, and find that the negative temperature jump still exist. Finally, we show that the local velocity distribution at the interface is so close to the Gaussian distribution that the existence/absence of local equilibrium state seems unable to determine by numerics in this way.

Standing in the Gulf: Politics, Covert Operations, and the Failures of Clinton's Iraq Policy
Creators: name: Kirschke-Schwartz, Marigny
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The United States has had a hostile relationship with Iraq since the conclusion of the First Gulf War, largely because of the policies of Iraq’s longtime dictator, Saddam Hussein. The American invasion of 2003 removed Saddam from power. But in the present, Iraq is a country in shambles. The eight years the United States occupied Iraq did little to mitigate the sectarian tensions that gave birth to a violent insurgency and sectarian violence. While the war to liberate the Iraqi people proved disastrous and had far-reaching consequences, one of the war’s fundamental goals was achieved early on: the ousting of Saddam Hussein. Much of the literature surrounding the 2003 invasion of Iraq focuses on the faulty intelligence on Weapons of Mass Destruction (WMDs) that was used to help justify the war.  Not enough attention is given to the twelve years the United States proclaimed its intention to remove Saddam from power. The primary goal of this thesis is to evaluate the origins, implementation, and overall shortcomings of the policy of “regime change” that became an official goal of the Clinton administration during 1998, but was pursued through a little known covert action program in the years prior. I will not be focusing on Iraq’s relationship with UNSCOM or the many arguments of the WMD debate, as they would make my scope too broad for the time allotted. Through personal interviews with CIA field officers, aides to President Clinton, and other specialists on the region, along with evaluation of congressional records and news articles, this thesis analyzes the policies of a time period in which most of the government records and documents are still classified. I will analyze how a policy of regime change became a policy of liberation, and how neither policy was made a top priority in either of President Clinton’s terms. A central question in my project is: Could better attention to Iraq policy under President Clinton have made a difference to the decision in 2003 to wage war in Iraq?
"Angels affect us oft": Angelic Imagery in the Poetic Works of John Donne
Creators: name: Richie, Claire Alexandra
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The father of metaphysical poetry and a well-known theologian, Donne’s two personas “Jack Donne” and “Doctor Donne” mark two different aspects of Donne’s distinctive poetic style: love and religion. The lighthearted love poems and the deeply troubled religious poems could almost be written by two different authors. Despite the stark contrast in subject matter, his poetry contains many recurring themes and images. Donne uses some of the same imagery to describe women and God. Issues of fidelity arise in both secular and religious poems. Images of the sun, hills that must be climbed, spheres and microcosms all feature in dual roles in Donne’s secular poetry and his religious works. One image appears constantly in his poems, often in some startling places: angels. Angels appear in over thirty of Donne’s poems and even more often in his prose writings and his sermons. Angelic imagery is used for a variety of purposes and makes Donne’s writing among the most unique of his time. While this paper will focus mainly on Donne’s poetry, it is important to consider Donne’s sermons and other religious writings to contextualize his views of angels and other heavenly beings.

description: Motivated by recent advances in the spectral theory of auto-covariance matrices, we are led to revisit a reformulation of Markowitz' mean-variance portfolio optimization approach in the time domain. In its simplest incarnation it applies to a single traded asset and allows to find an optimal trading strategy which - for a given return - is minimally exposed to market price fluctuations. The model is initially investigated for a range of synthetic price processes, taken to be either second order stationary, or to exhibit second order stationary increments. Attention is paid to consequences of estimating auto-covariance matrices from small finite samples, and auto-covariance matrix cleaning strategies to mitigate against these are investigated. Finally we apply our framework to real world data.

description: Based on the competition between $γ$-stable and $γ$-rigid collective motions mediated by a rigidity parameter, a two-parameter exactly separable version of the Bohr Hamiltonian is proposed. The $γ$-stable part of the Hamiltonian is restricted to stiff oscillations around the $γ$ value of the rigid motion. The separated potential for $β$ and $γ$ shape variables is chosen such that in the lower limit of this parameter, the model recovers exactly the ES-$X(5)$ model, while in the upper limit it tends to the prolate $γ$-rigid solution $X(3)$. The combined effect of the rigidity and stiffness parameters on the energy spectrum and wave function is duly investigated. Numerical results are given for few nuclei showing such ambiguous behaviour.

The Effect of Estrogen on Cardiac-Skeletal Muscle Biomarkers Following Prolonged Aerobic Exercise in Eumenorrheic Women
Creators: name: Williams, Timmons
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Purpose: This study assessed the influence of estrogen (E2) on skeletal muscle creatine kinase (CK) and cardiac muscle CK (CK-MB) responses to prolonged aerobic exercise. Elevations in these biomarkers are indicative of muscle trauma-damage. Methods: Eumenorrheic women (n=10) who were physically active completed two 60-minute treadmill running sessions at ~60-65% maximal intensity during low E2 (midfollicular menstrual phase) and high E2 (midluteal menstrual phase) hormonal conditions. Blood samples were collected prior to exercise (following supine rest), immediately post-, 30 min post-, and 24 hr post-exercise to determine changes in muscle biomarkers. Resting blood samples confirmed appropriate E2 hormonal levels Results: CK concentrations increased following exercise and at 24 hr post-exercise were higher in the midfollicular phase (p<0.001). However, CK-MB concentrations were unaffected by E2 level or exercise (p=0.442). Conclusions: E2 levels influence the CK biomarkers response for skeletal but not cardiac muscle following prolonged aerobic exercise. These findings imply elevated E2 is protective of skeletal muscle from exercise-induced damage.

description: Combining strong magnetic anisotropy with strong exchange interaction is a long standing goal in the design of quantum magnets. The lanthanide complexes, while exhibiting a very strong ionic anisotropy, usually display a weak exchange coupling, amounting to only a few wavenumbers. Recently, an isostructural series of mixed Ln$^{3+}$-N$_2^{3-}$-Ln$^{3+}$ (Ln $=$ Gd, Tb, Dy, Ho, Er) have been reported, in which the exchange splitting is estimated to reach hundreds wavenumbers. The microscopic mechanism governing the unusual exchange interaction in these compounds is revealed here by combining detailed modeling with density-functional theory and {\it ab initio} calculations. We find it to be basically kinetic and highly complex, involving non-negligible contributions up to seventh power of total angular momentum of each lanthanide site. The performed analysis also elucidates the origin of magnetization blocking in these compounds. Contrary to general expectations the latter is not always favored by strong exchange interaction.

description: We present a systematic assessment of the structural properties, the electronic density of states, the charge densities, and the phase stabilities of AgInSe$_2$ and AuInSe$_2$ using screened exchange hybrid density functional theory, and compare their properties to those of CuInSe$_2$. For AgInSe$_2$, hybrid density functional theory properly captures several experimentally measured properties, including the increase in the band gap and the change in the direction of the lattice distortion parameter $u$ in comparison to CuInSe$_2$. While the electronic properties of AuInSe$_2$ have not yet been experimentally characterized, we predict it to be a small gap ($\approx 0.15$ eV) semiconductor. We also present the phase stability of AgInSe$_2$ and AuInSe$_2$ according to screened-exchange density functional theory, and compare the results to predictions from conventional density functional theory, results tabulated from several online materials data repositories, and experiment (when available). In comparison to conventional density functional theory, the hybrid functional predicts phase stabilities of AgInSe$_2$ in better agreement with experiment: discrepancies in the calculated formation enthalpies are reduced by approximately a factor of three, from $\approx$ 0.20 eV/atom to $\approx$ 0.07 eV/atom, similar to the improvement observed for CuInSe$_2$. We further predict that AuInSe$_2$ is not a stable phase, and can only be present under non-equilibrium conditions.

description: Introduction: Precision medicine describes a future state where drug treatment is selected based on a patient’s disease and genetics. Precision dosing is a key component of precision medicine, in whichmedications are adjusted to each individual patient’s relevant characteristics. The electronic medical record (EMR) has enabled the development of precision dosing tools that can provide prescribers with instantaneous recommendations for dose adjustments based on patient characteristics recorded in the EMR. Although these dosing tools exist, data evaluating the prevalence of these tools in the United States (U.S.) are lacking. The purpose of this study was to assess the availability and capability of electronic dosing tools across U.S. hospitals.Methods: We conducted a cross-sectional, observational study using a self-report questionnaire among U.S. pharmacists to evaluate the prevalence of and attitudes toward dosing tools. The survey wasdeveloped using Qualtrics (Qualtrics, Provo, UT) and sent to the chairs of relevant ACCP PRN Networks for dissemination to their members. Data were analyzed based on frequency of response to each survey question.Results: One-hundred fourteen pharmacists completed the survey, of which 30% reported having dosing tools integrated into their EMR. Among those respondents who do not have dosing tools available, 59% reported that they have strong interest in obtaining these tools.

Image Parsing with a Wide Range of Classes and Scene-Level Context
Creators: name: George, Marian
Publisher: name: arXiv
Year: 2015
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: This paper presents a nonparametric scene parsing approach that improves the overall accuracy, as well as the coverage of foreground classes in scene images. We first improve the label likelihood estimates at superpixels by merging likelihood scores from different probabilistic classifiers. This boosts the classification performance and enriches the representation of less-represented classes. Our second contribution consists of incorporating semantic context in the parsing process through global label costs. Our method does not rely on image retrieval sets but rather assigns a global likelihood estimate to each label, which is plugged into the overall energy function. We evaluate our system on two large-scale datasets, SIFTflow and LMSun. We achieve state-of-the-art performance on the SIFTflow dataset and near-record results on LMSun.

description: We study the action of the BMS group in critical, bosonic string theory living on a target space of the form $\mathbb{M}^{d}\times C$. Here $M^{d}$ is $d$-dimensional (asymptotically) flat spacetime and $C$ is an arbitrary compactification. We provide a treatment of generalized Ward--Takahashi identities and derive consistent boundary conditions for any $d$ from string theory considerations. Finally, we derive BMS transformations in higher dimensional spacetimes and show that the generalized Ward--Takahashi identity of BMS produces Weinberg's soft theorem in string theory.

A 1-D position sensitive Parallel Grid Avalanche Counter detector (PGAC) was used at the exit of a spectrograph magnet, enabling us to measure the intensity of several charge states simultaneously. The number of charge states measured for each beam constituted more than 99% of the total equilibrium charge state distribution for that elements. Currently, little experimental data exists for equilibrium charge state distributions for heavy ions with 19

description: We use the Planck HFI channel maps to make an all sky map of $μ$-distortion fluctuations. Our $μ$-type distortion map is dominated by the $y$-type distortion contamination from the hot gas in the low redshift Universe and we can thus only place upper limits on the $μ$-type distortion fluctuations. For the amplitude of $μ$-type distortions on $10'$ scales we get the limit on root mean square (rms) value $μ_{rms}^{10'}< 6.4\times 10^{-6}$, a limit 14 times stronger than the COBE-FIRAS ($95\%$ confidence) limit on the mean of $< μ> <90\times 10^{-6}$. Using our maps we also place strong upper limits on the auto angular power spectrum of $μ$, $C_{\ell}^{μμ}$ and the cross angular power spectrum of $μ$ with the CMB temperature anisotropies, $C_{\ell}^{μT}$. The strongest observational limits are on the largest scales, $\ell(\ell+1)/(2π)C_{\ell}^{μμ}|_{\ell=2-26}

Black mothers of blind/low vision children: perspectives and experiences of advocacy and navigating the education system
Creators: name: Coleman, Monique A.
Publisher: name: No Publisher Supplied
Year: 2023

description: Blind and low vision youth represent a diverse, low incidence disability student population in United States public schools. This qualitative study investigated the perspectives of four Black mothers and grandmothers, each primary caregivers of blind/low vision (BLV) children, related to their experiences with navigating the education system and advocating for their children. Methods: Individual interviews and a focus group were employed to elicit and explore the caregivers’ lived experiences of special education processes and parental advocacy at the intersections of race, class, and disability. The research was grounded in a critical race theory (CRT) analysis, via Yosso’s (2006) community cultural wealth framework. An intersectionality lens was also applied to explore the ways in which the caregivers’ perspectives and experiences were shaped by their identities as Black women. Findings: Each of the mothers and grandmothers faced several similar challenges and obstacles as they navigated the school system and advocated for what they perceived to be an appropriate and quality education for their children. By engaging strategic mothering decisions and drawing on their storehouse of community cultural wealth, the caregivers sustained high levels of parental involvement and experienced some key advocacy successes over the course of the school year. Discussion: The findings provide insights on a segment of the culturally and linguistically (CLD) diverse population of families of BLV children that has received little attention in the extant literature. There are several implications for theory and research focused on issues pertaining to Black families of BLV; culturally responsive family engagement practices; and personnel preparation and professional development.

Investigation into Alpha Particle Backgrounds in the MAJORANA DEMONSTRATOR
Creators: name: Nance, John
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Questions about the neutrino’s mass and nature have developed into an important area of
modern physics research. While neutrino oscillations have shown that neutrinos have non-zero mass,
their absolute mass has yet to be determined. Additionally, since they possess no charge, it is possible
that neutrinos are Majorana particles, meaning that they are indistinguishable from their antiparticle.
The MAJORANA DEMONSTRATOR (MJD) aims to probe the neutrino’s absolute mass, and its
Majorana nature by searching for neutrinoless double-beta decay (0υββ). Backgrounds from alpha
particles potentially pose a problem to this experiment. Alpha particles are produced from elements in
the 238-uranium (238U) and 232-thorium (232Th) decay chains, and although alpha particle energies are
typically higher than the 0υββ Q-value, they can lose energy before entering the active mass of the
detector, and deposit energy near the 0υββ Q-value. Initially, the dependence of alpha rates on detector
geometry is explored. Then, two studies conducted on data collected by MJD are presented, one
looking for correlations between observed alpha rates and detectors’ processing history and
manufacturing date, and the other looking for alpha-alpha and beta-alpha coincidence events in the 238U
and 232Th decay chains. No correlation is found between a detector’s processing history and its alpha
rate, but a detector’s age shows a weak negative correlation with alpha rate, suggesting the decay of
plated out radon progeny. Results of the coincidence study do not provide strong evidence of the
presence of 232Th or 238U signatures in MJD data.

description: Describes preliminary analysis using the data from the Open Science Collaboration's Reproducibility Project (2015). After coding the studies as to whether deception was a feature of their procedures, it is shown that replications that involved deception had an 89% probability of not being replicated, as opposed to the 63% failure rate of studies that did not involve deception. This result will be part of a larger project exploring the nature of experimental deception as a scientific technique.

description: Several celestial bodies in co-orbital configurations exist in the solar system. However, co-orbital exoplanets have not yet been discovered. This lack may result from a degeneracy between the signal induced by co-orbital planets and other orbital configurations. Here we determine a criterion for the detectability of quasi-circular co-orbital planets and develop a demodulation method to bring out their signature from the observational data. We show that the precision required to identify a pair of co-orbital planets depends only on the libration amplitude and on the planet's mass ratio. We apply our method to synthetic radial velocity data, and show that for tadpole orbits we are able to determine the inclination of the system to the line of sight. Our method is also valid for planets detected through the transit and astrometry techniques.
