Universalism Calling: French Distortion and Invention of the Image of China, From Jesuits to Enlightenment Philosophes, circa 1560-1800
Creators: name: Ji, Ruoyu
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Therefore, there were mainly three kinds of people who wrote about China in early modern
France. There were Jesuits, who were the conservative intellectuals aiming to spread
Christianity in China and to preserve Catholic power in France. There were political writers
who were in favor of China, represented by Voltaire. And, of course, there were people like
Montesquieu, who were intellectuals showing contempt for China. The identities of all three
kinds of writers mingled with their distinctive judgments of China, complicating the second
question I posed: What made them diverge on the idea of China? In order to solve this question,
I studied the writings of the Jesuits, Voltaire, and Montesquieu, and consulted with secondary
sources on the topics. I will argue in three following chapters that the French writers who wrote
about China in the early modern period, no matter if they were Jesuits or Enlightenment
philosophes, or if they were praising or criticizing China, all fell into a recurring pattern: The
conceptions of China in their writings were dynamically shaped by the universalistic beliefs
they individually held and they all needed to process, to some extent, the image of China by
distortion, invention, or selection, to match their original intellectual purpose in using China
for a larger cultural purpose.
Daoism and Posthuman Subjectivity in Ursula K. Le Guin’s “The Lathe of Heaven”
Creators: name: Harry, Owen
Publisher: name: RSAJournal
Year: 2023

description: Posthumanists consistently challenge traditional notions of the human subject as bounded and autonomous. For these theorists, American environmental literature has proven to be a valuable source of more relational models of subjectivity in which humans are recognized as interconnected with nonhumans. However, the significant influence of the religious imagination on this literary tradition has largely been disregarded by posthuman ecocritics, and so too has its potential contribution to combating anthropocentrism. Building on recent arguments for parallels between posthumanism and Daoist thought, this article analyzes the work of Ursula K. Le Guin, whose speculative fiction has been acclaimed by posthumanists for its experiments in post-anthropocentric subjectivity, but whose strong Daoist influence has not been recognized by these same critics for its role in such experiments. I argue that Le Guin’s central character in her most explicitly Daoist novel The Lathe of Heaven (1971) embodies Daoist concepts in ways that align closely to Rosi Braidotti’s model of posthuman subjectivity. Beyond this recognition of compatibility between the two perspectives, I argue that reading the novel in light of recent re-evaluations of the concept of wuwei (non-action) also suggests an alternative conception of human agency that may inform the posthumanist project.

description: This paper considers the problem of temperature regulation in multicore processors by dynamic voltage-frequency scaling. We propose a feedback law that is based on an integral controller with adjustable gain, designed for fast tracking convergence in the face of model uncertainties, time-varying plants, and tight computing-timing constraints. Moreover, unlike prior works we consider a nonlinear, time-varying plant model that trades off precision for simple and efficient on-line computations. Cycle-level, full system simulator implementation and evaluation illustrates fast and accurate tracking of given temperature reference values, and compares favorably with fixed-gain controllers.

Poetry, Animals and the Imaginative Ethnographies of Creaturely Lives
Creators: name: Desmond, Jane
Publisher: name: RSAJournal
Year: 2023

description: In conversation with recent work on post-humanism and theorizations of the “more-than-human” world, I explore the capacities of literature, and especially contemporary poetry, to function as a sort of imaginative ethnography. Considering selected poems by US authors as a mode of “multispecies ethnography,” I draw on anthropological debates about ways of knowing more-than-human worlds, and the challenges of articulating that (necessarily anthropocentric) speculative knowledge. I argue that poetry, with its emphasis on condensation and multi-layered semiotics, along with its affective dimensions built through craft tools of sound, image, rhythm and line breaks, can function as a form of transpecies imaginative translation. It may even cultivate empathy, ultimately building toward change in human-animal relations in the world, through acts of writing and interpretation that imaginatively translate across the species divides, articulating shared human and more-than-human worlds.

Wanderers on the Way Into the Neighborhood of Being
Creators: name: Iuli, Cristina
Publisher: name: RSAJournal
Year: 2023

description: The article discusses Katherine Larson’s first collection of poems, Radial Symmetry (2013), as a work that interrogates the relation between poetics and knowledge of life-forms. First, it provides the background for reading Larson’s poetry in the context of aesthetics as a domain in which literary and philosophical discourse overlap, and then it situates Larson’s work more specifically within philosophical the discourse of “nature” framed, on the one hand, by Ralph Waldo Emerson’s pluralistic, non-representational view of language in Nature and, on the other, by Martin Heidegger’s reflections on Being, language and beings in “The Question Concerning Technology”. Finally, the essay delivers a close reading of some of Larson’s poems in order to exemplify the difference they make in engaging “nature,” “life,” and “Being” by means of language: whether by taking care of those entities, or by reducing them to “standing reserve.” Larson’s poems provide an apt focus for a wider discussion about the viability of poetry as a means to approach the morphological diversity of life right at the time of its human-driven sixth mass extinction.

“All Nature Teems with Life”
Creators: name: Martínez Serrano, Leonor María
Publisher: name: RSAJournal
Year: 2023

description: Drawing on Rosi Braidotti’s thinking on the need for “a downsizing of human arrogance” and solidarity with other (non)humans,” as well as on Rob Nixon’s and Saskia Sassen’s insights into the perverse logic of capitalism and the slow violence brought about by environmental degradation, this article examines the representation of anthropogenic wastelands in American poet Robert Hass’s acclaimed Time and Materials: Poems 1997-2005. The concept of wasteland as an image of decadence, crisis and a mindset marked by exhaustion is present in a significant set of poems in Hass’s collection, where two kinds of wastelands can be discerned. The first kind concerns the devastation of spaces, terraforming, overexploitation, species extinction and the depletion of natural resources in the Anthropocene, which is particularly palpable in the ten-part “State of the Planet,” an ambitious piece that condenses the story of the Earth from the Big Bang to the present. The second kind of wasteland concerns the massive corporeal waste brought about by the devastating wars punctuating the twentieth century. As a poet, Hass is called on to bear witness to his time, one that seems to be intent on destroying the biosphere as the oikos life has built for itself at the expense of relentless economic growth. Yet he is prompt to write other poems, not of denunciation but of exultation, that sing of the beauty and vulnerability of the physical world homo sapiens is a part of, not apart from.

description: We investigate the properties of the galaxies selected from the deepest 850-micron survey undertaken to date with SCUBA-2 on the JCMT. This deep 850-micron imaging was taken in parallel with deep 450-micron imaging in the very best observing conditions as part of the SCUBA-2 Cosmology Legacy Survey. A total of 106 sources were uncovered at 850 microns from ~150, sq. arcmin in the centre of the COSMOS/UltraVISTA/CANDELS field, imaged to a typical rms depth of ~0.25 mJy. We utilise the wealth of available deep multi-frequency data to establish the complete redshift distribution for this sample, yielding = 2.38 +- 0.09, a mean redshift comparable with that derived for all but the brightest previous sub-mm samples. We have also been able to establish the stellar masses of the majority of the galaxy identifications, enabling us to explore their location on the star-formation-rate:stellar-mass (SFR:M*) plane. Crucially, our new deep sample reaches flux densities equivalent to SFR ~ 100 Msun/yr, enabling us to confirm that sub-mm galaxies form the high-mass end of the `main sequence' (MS) of star-forming galaxies at z > 1.5 (with a mean specific SFR of sSFR = 2.25 +- 0.19 /Gyr at z ~ 2.5). Our results are consistent with no significant flattening of the MS towards high masses at these redshifts, suggesting that reports of such flattening possibly arise from under-estimates of dust-enshrouded star-formation activity in massive star-forming galaxies. However, our findings add to the growing evidence that average sSFR rises only slowly at high redshift, resulting in log(sSFR) being an apparently simple linear function of the age of the Universe.

Blurring the Line between Civilian and Military: The Changing Nature of the Town-Base Relationship in Jacksonville, North Carolina
Creators: name: Johnson, Crystal M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: This thesis reflects the personal and intellectual interests that I bring to investigating how and why military towns form as they do. This thesis examines the extent to which America’s aggressive military preparedness affected local communities in which military installations were established and the nature of the relationships that developed between civilians and the military. How did locals accommodate the changes brought by the base? Did the locals resent the base and the service members or did they embrace the economic prosperity they brought to the area? Did a prolonged military presence improve social conditions such as race relations in these communities or did it hurt them? These are questions that I have explored by broadly researching military base construction and the development of military communities in the United States during the twentieth century. Drawing from the Jacksonville Daily News and the Camp Lejeune Globe, census data, oral histories, and government reports, this thesis analyzes the history of the interaction between Camp Lejeune and Jacksonville through the use of three case studies. Through these case studies, I examine specific events that have largely shaped the relationship and which exemplify the changing attitudes and mentalities documented in the area.
Topological Constraints and Rigidity of Network Glasses from Molecular Dynamics Simulations

description: Due to its non-crystalline nature, the glassy state has remained one the most exciting scientific challenges. To study such materials, Molecular Dynamics (MD) simulations have been extensively used because they provide a direct view into its microscopic structure. MD is therefore used not only to reproduce real system properties but also benefits from detailed atomic scale analysis. Unfortunately, MD shows inherent limitations because of the limited computational power. For instance, only the simulations of small systems are currently permitted, which prevents from studying small compositional changes, although it is well known that they can dramatically alter system properties. At this stage, it is tempting to follow topological constraint theory, which aims at describing macroscopic properties of the glass relying only on the connectivity of individual atoms, thus considering the complicated glass network as simple mechanical trusses. Thanks to only basic hand calculations, this theory has been successful in predicting complex composition and temperature behavior of glass properties, such as the glass forming ability, the viscosity of the corresponding liquid or the elasticity. The purpose of my PhD work is to connect these successful approaches based only on the topology of the underlying low-temperature network with properties that can be obtained from MD calculations. It should thus allow for an increased applicability of rigidity theory.

description: A pronounced local in-gap zero-energy bound state (ZBS) has been observed by recent scanning tunneling microscopy (STM) experiments on the interstitial Fe impurity (IFI) and its nearest-neighboring (nn) sites in $\mathrm{FeTe_{0.5}Se_{0.5}}$ superconducting (SC) compound. By introducing a new impurity mechanism, the so-called tunneling impurity, and based on the Bogoliubove-de Gennes (BDG) equations we investigated the low-lying energy states of the IFI and the underlying Fe-plane. We found the peak of ZBS does not shift or split in a magnetic field as long as the tunneling parameter between IFI and the Fe-plane is sufficiently small and the Fe-plane is deep in the SC state. Our results are in good agreement with the experiments. We also predicted that modulation of spin density wave (SDW), or charge density wave (CDW) will suppress the intensity of the ZBS.

Characterizing a novel signalling pathway in Pseudomonas entomophila: Elucidation of the signal cascade initiated by Pseudomonas virulence factor (PVF) through transposon mutagenesis
Creators: name: Knechel, Martina
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Pseudomonas virulence factor (PVF) is a signaling molecule synthesized by proteins encoded in the pvf biosynthetic gene cluster of the Drosophila melanogaster pathogen Pseudomonas entomophila. Previous research has shown that when these genes are mutated, the ability of this bacterium to persist in a eukaryotic host and have virulent effects is greatly reduced.1 Furthermore, the Li lab has identified homologues of the pvf gene cluster in over 300 strains of bacteria with a variety of different hosts that span the domain, Eukarya. While its ubiquity and importance to bacterial virulence has been established, little is actually known about the signaling pathway PVF initiates in neighboring P. entomophila cells. The goal of this project was to identify the genes involved in this novel signaling pathway, starting from the reception of the PVF signaling molecule at the cell membrane to the initiation of transcription. To this end, Tn5 mutagenesis was used to disrupt individual genes in a reporter strain of P. entomophila containing a PSEEN0973::lacZ insertion and a reporter strain of P. entomophila containing a PSEEN5493::lacZ insertion. Cells that took up the Tn5 plasmid were selected by antibiotic resistance and screened using a blue/white screen. Resultant white colonies exhibited disruptions in genes vital to the signaling pathway as they were not able to produce β-galactosidase, whereas blue colonies had fully functional pathways. These white colonies were further screened with quantitative assay that measured the conversion of ortho-nitrophenyl-β-galactosidase to orthonitrophenol, a reaction catalyzed by β-galactosidase. A total of 8,500 colonies were screened, and 86 white colonies were identified and quantitatively screened. Arbitrary PCR was used to investigate the locations of the Tn5 insertions in the genome. With the aid of bioinformatics, we have identified a putative histidine kinase and methylesterase that are likely involved in the PVFinitiated signaling pathway.

description: There is a scarcity of information on the role of Artificial Intelligence (AI) in enhancing sustainable forest management worldwide. Using a literature review, this study explores the case of Kenya, with the aim of contributing to a better understanding of the strategies needed to promote the role of AI in the development and sustainability of forests. Results reveal that AI deployment in forestry is still in the infancy stages. The country has some AI technologies in use to promote forest management. Moreover, both public and private, local, and international organizations are actively involved in developing AI applications for forestry to consider the social, economic, and environmental facets of sustainable forest management. Additionally, no studies have been conducted on the public perception and opinions regarding the use and role of AI in sustainable forest management in Kenya. These study findings pose the risk of limited progress, technological gaps, and uncertain impacts on key green infrastructure development priorities; for example, the achievement of 30% tree cover by 2032 and a host of international development obligations, as well as the continued misunderstanding regarding public perceptions of AI deployment in forestry. There is thus an urgent need for accelerating AI research and development in forestry, fostering collaboration between public and private sectors, conducting studies on public perceptions, and ensuring ethical and sustainable AI implementation.

description: This study explored Thai secondary school students’ English language learning with an aim to investigate the effects of integrating drama-based activities and Facebook on the students’ English speaking skills, attitudes towards and motivation in learning the English language. The study used a mixed methods approach to collect both quantitative and qualitative data. A total of 40 students from two Grade 12 classes and 2 teachers of English at Srinakarindra the Princes Mother School, Nongbualamphu, Thailand participated in this study. They were selected using purposive sampling and assigned to two groups of 20 students each: the experimental group (using drama-based activities and Facebook) and the control group (using traditional face-to-face learning activities). The data was collected through English speaking tests, Attitude and Motivation Test Battery (AMTB) questionnaires, classroom observations, classroom evaluations and interviews. Throughout the data collection process, reflective journals were used to help the students reflect on learning activities as the study progressed. The findings of the study indicate that the integration of drama-based activities and Facebook had positive effects on the students’ speaking skills. The integration technique encouraged the students to be more active in their learning and increased their motivation and positive attitudes towards learning the English language. The integration technique also provided the students with more interaction and a flexible learning environment to actively communicate and collaborate with their teachers of English and peers. The activities also led the students to develop not only their speaking skills but also other skills that are important for language learning in the classroom, such as discussion and writing skills. The findings of the study may be beneficial to researchers and teachers who aim to develop students’ EFL speaking skills and active learning, while enhancing positive motivation and attitudes towards learning and speaking English. The study offers alternative English teaching methods that integrate a social media platform such as Facebook with drama-based learning activities to produce an interactive and motivated learning approach. The findings of the study also provide insightful descriptions of how drama-based activities and Facebook can be effectively integrated into the curriculum to assist Thai EFL secondary school students to develop their English-speaking skills.

description: We discuss (2+1)-dimensional gapless surface theories of bulk (3+1)-dimensional topological phases, such as the BF theory at level $\mathrm{K}$, and its generalization. In particular, we put these theories on a flat (2+1) dimensional torus $T^3$ parameterized by its modular parameters, and compute the partition functions obeying various twisted boundary conditions. We show the partition functions are transformed into each other under $SL(3,\mathbb{Z})$ modular transformations, and furthermore establish the bulk-boundary correspondence in (3+1) dimensions by matching the modular $\mathcal{S}$ and $\mathcal{T}$ matrices computed from the boundary field theories with those computed in the bulk. We also propose the three-loop braiding statistics can be studied by constructing the modular $\mathcal{S}$ and $\mathcal{T}$ matrices from an appropriate boundary field theory.

Misleading sensations? How body signal beliefs interact with sympathetic reactivity and interoceptive ability to amplify affective stress
Creators: name: Bonar, Adrienne
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Guided by the theory of constructed emotion, we developed a preliminary measure of interoceptive body signal beliefs and examined how such beliefs relate to trait interoceptive ability, sympathetic nervous system reactivity and affective stress during a stress induction task. During the first session of the study, we used a heartbeat detection task as a measure of interoceptive ability and collected self-reported data on participants’ bodily signal beliefs. In a follow-up session, we collected continuous measures of sympathetic response as participants completed the Trier Social Stress Test. Through hierarchical regression analyses, we found that sympathetic reactivity predicted both negative affect and somatic intensity during the stress induction task. Additionally, the interaction between negative beliefs about one’s bodily signals and interoceptive ability significantly predicted somatic intensity during stress. Moreover, we found a significant interaction between sympathetic reactivity and positive body signal beliefs in predicting negative affect, suggesting that positive body signal beliefs may buffer the relation between sympathetic reactivity and negative affect. These findings collectively suggest that the beliefs individuals have about the meaning of their bodily signals, in addition to sympathetic reactivity and interoceptive ability, can play a key role in amplifying affective stress.

description: The idea of synthesizing ultra-fine nanoparticles with a regular rhombohedral morphology was to achieve a significantly high tensile strength in marble (rock) which is known to be weaker in tension mode. Furthermore, the mechanical response data for nano-CaCO3 in context of tensile properties in thermosets is limited. 1. We propose impressively high tensile strength and modulus in thermosets (an enhancement of ~51% and ~28%) at just 1wt% by synthesizing uniform-sized nano-CaCO3 particles (stone) which is an arduous task. 2. Adding a brittle filler (nano-CaCO3) to a brittle matrix resulted in a novel behaviour of ~40% enhancement in ductility which is difficult to achieve. 3. To date, no HR-TEM characterization of a disordered, diffused dolomitic stone with atomic arrangement at 1 nm resolution has been reported. 4. An enhancement in tensile properties without any surface modification or concomitance with natural fibres at very low loadings (1wt%) would pave an innovative pathway for a sustainable nano-filler in reducing carbon footprints and enabling circular economy by transforming concrete technology for a greener construction industry.

description: We study how the color and polarization of ultrashort pulses of visible light can be used to control the demagnetization processes of the antiferromagnetic insulator Cr$_2$O$_3$. We utilize time-resolved second harmonic generation (SHG) to probe how changes in the magnetic and structural state evolve in time. We show that, varying the pump photon-energy to excite either localized transitions within the Cr or charge transfer states, leads to markedly different dynamics. Through a full polarization analysis of the SHG signal, symmetry considerations and density functional theory calculations, we show that, in the non-equilibrium state, SHG is sensitive to {\em both} lattice displacements and changes to the magnetic order, which allows us to conclude that different excited states couple to phonon modes of different symmetries. Furthermore, the spin-scattering rate depends on the induced distortion, enabling us to control the timescale for the demagnetization process. Our results suggest that selective photoexcitation of antiferromagnetic insulators allows fast and efficient manipulation of their magnetic state.

description: Geophysical inversions give non-uniqueness solutions and unless constrained by appropriate initial values and geological constraints can give unrealistic results. One of the critical constraints can be the physical property values of different lithologies. We have compiled a density and magnetic susceptibility database consisting of thousands of measurements collated from different organisations and/or projects across the Abitibi greenstone belt. Statistical tools (histograms, quantile-quantile probability plots and boxplots) are applied to characterise systematically major and minor lithologies. We observed that the magnetic susceptibility frequently has a bimodal distribution, while density is typically unimodal. Our results are summarized in a table that includes the representative mean (or median) and a range of acceptable values. These values can be used to better understand the regional geology, but in this paper, we used the tabulated properties in a geophysical/petrophysical inversion of gravity data from the Chicobi area in the Abitibi subprovince to show the level of improvements that the petrophysical constraints can add to an unconstrained model. When our density database is used to seed the initial guess in a gravity inversion, an anomalous zone becomes apparent that was less evident on an unconstrained inversion.
Nonspecific orofacial symptoms as risk factors for first-onset TMD and chronic TMD
Creators: name: Sun, Jenny
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Previous studies found the count of 6 nonspecific orofacial symptoms was one of
the most important predictors of first-onset TMD. We further examined the influence of
these symptoms (jaw siftness, cramping, fatigue, pressure, soreness, and ache) on first-onset
TMD and chronic TMD among U.S. adults aged 18 to 44 years in the OPPERA
study. We identified 259 first-onset TMD cases and 185 chronic TMD cases. Hazard
ratios were computed to estimate the association between each nonspecific orofacial
symptom and first-onset TMD. We calculated odds ratios to measure the association
between each symptom and chronic TMD. A principal component analysis was used to
determine if all six symptoms are measures of a single underlying construct or largely
independent of one another. Multivariable cox models quantified the combined effects of
non-specific orofacial symptoms, clinical orofacial measures, and first-onset TMD.
Multivariable logistic models examined these same associations on chronic TMD. Each
nonspecific orofacial symptom was significantly associated with increased incidence of
first-onset TMD and greater odds of chronic TMD. Results from the principal component
analysis suggest it is reasonable to summarize the six variables by simply counting the
number of symptoms reported. In the multivariable analysis, nonspecific orofacial
symptoms significantly predicted first-onset TMD (HR=1.33; 95% CI: 1.11-1.59) and
chronic TMD (OR=3.06; 95% CI: 2.03-4.97). The results indicate that the count of
nonspecific orofacial symptoms is an independent risk factor and not a surrogate variable
for pain.

description: The central question of this thesis focuses on voluntary school desegregation plans and their adoption. With more than 13,500 school districts in the country in the 2013-2014 school year, and less than 100 districts engaged in voluntary desegregation, these districts are extremely rare (National Center for Education Statistics, 2016). Why is it that some rare school districts choose to adopt voluntary school desegregation policies, while others within the same state do not? It is the goal of this study to better understand the dynamics of communities that have willfully decided to enter into a historically challenging collective bargaining process, and have successfully implemented these policies. It is important to study these school districts because the successful adoption of such strategies may be the nation’s most viable approach to counteracting segregation in the modern era.

description: The coherent generation of light, from masers to lasers, relies upon the specific structure of the individual emitters that lead to gain. Devices operating as lasers in the few-emitter limit provide opportunities for understanding quantum coherent phenomena, from THz sources to quantum communication. Here we demonstrate a maser that is driven by single electron tunneling events. Semiconductor double quantum dots (DQDs) serve as a gain medium and are placed inside of a high quality factor microwave cavity. We verify maser action by comparing the statistics of the emitted microwave field above and below the maser threshold.

description: We construct the solutions of slowly rotating gravastars with a thin shell. In the zero-rotation limit, we consider the gravastar composed of a de Sitter core, a thin shell, and Schwarzschild exterior spacetime. The rotational effects are treated as small axisymmetric and stationary perturbations. The perturbed internal and external spacetimes are matched with a uniformly rotating thin shell. We assume that the angular velocity of the thin shell, $Ω$, is much smaller than the Keplerian frequency of the nonrotating gravastar, $Ω_k$. The solutions within an accuracy up to the second order of $Ω/Ω_k$ are obtained. The thin shell matter is assumed to be described by a perfect fluid and to satisfy the dominant energy condition in the zero-rotation limit. In this study, we assume that the equation of state for perturbations is the same as that of the unperturbed solution. The spherically symmetric component of the energy density perturbations, $δσ_0$, is assumed to vanish independently of the rotation rate. Based on these assumptions, we obtain many numerical solutions and investigate properties of the rotational corrections to the structure of the thin shell gravastar.

Tunable liquid-liquid critical point in an ionic model of silica

description: Recently it was shown that the WAC model for liquid silica [L. V. Woodcock, C. A. Angell, and P. Cheeseman, J. Chem. Phys. 65, 1565 (1976)] is remarkably close to having a liquid-liquid critical point (LLCP). We demonstrate that increasing the ion charge separates the global maxima of the response functions, while reducing the charge smoothly merges them into a LLCP; a phenomenon that might be experimentally observable with charged colloids. An analysis of the Si and O coordination numbers suggests that a sufficiently low Si/O coordination number ratio is needed to attain a LLCP.

description: Device applications involving topological insulators (TIs) will require the development of scalable methods for fabricating TI samples with sub-micron dimensions, high quality surfaces, and controlled compositions. Here we use Bi-, Se-, and Te-bearing metalorganic precursors to synthesize TIs in the form of nanowires. Single crystal nanowires can be grown with compositions ranging from Bi2Se3 to Bi2Te3, including the ternary compound Bi2Te2Se. These high quality nanostructured TI compounds are suitable platforms for on-going searches for Majorana Fermions.
Comparison of clopidogrel pharmacokinetics in infants vs. adults using in vitro metabolism

description: Clopidogrel is indicated for the prevention of thrombotic complications in infants (aged 0 to 12 months) undergoing catheterization and device implant procedures due to congenital heart defects. Clopidogrel requires cytochrome P450 (CYP) 2C19 for conversion to the active metabolite. However, CYP2C19 levels in infants do not reach adult levels until >6 months of age. It is therefore surprising that a 0.2 mg/kg/day clopidogrel dose in infants achieves platelet inhibition comparable to that observed in adults on 75 mg/day (~1 mg/kg/day). A safe and efficacious dose of clopidogrel in infants is still unknown. This study aims to compare clopidogrel in vivo clearance between infants and adults, and determine the mechanism that could explain the difference in potency of clopidogrel in these two populations.

description: The rapid urbanization in most Low- and Middel-Income Countries (LMICs) combined with an insufficient supply of low-cost housing is leading to the growth of deprived urban areas (commonly known as slums or informal settlements). The UN is estimating that around 90% of the urban growth will happen in LMICs, mostly in deprived areas. The improvement of living and environmental conditions in these areas are on the global development agendas (e.g., SDGs, NUA). However, there are commonly insufficient data to guide policies and local actions that would be required understanding specific local conditions and needs. The presentation shows examples of ongoing efforts to build open data on living and environmental conditions, combining Earth Observation and Geospatial data with local knowledge. The projects focus on the development of data ecosystems with local stakeholders. For example, within IDeAMapSudan, a Geonode was developed to share data with an between local stakeholders. Furthermore, within the recently launched 2nd phase of IDEAMAPS, a data ecosystem will be co-designed that supports the integration and exchange of data between local community groups, governments, and academia.
Deranged and Defamed: U.S. Courts and Defamation Suits Involving Mental Illness Imputations After the Americans with Disabilities Act

description: The purpose of this thesis is to explore and analyze the way U.S. courts have treated
defamation claims involving the imputation of mental illness. Specifically, this thesis looks at 11 cases, both state and federal, following the passage of the Americans with Disabilities Act of 1990, in which discrimination based on disability was prohibited.
In eight of the cases analyzed, the alleged defamatory statement was determined to be
non-actionable opinion or hyperbole. In two of the cases the statements were found to be
defamation per se and in one case the statement was determined to not impute mental illness and to be substantially true. This thesis looks specifically at how each court in the non-actionable opinion or hyperbole cases came to that determination. Both ambiguity and inconsistencies were found among the courts in defining what constitutes an opinion protected by the First Amendment. This thesis also approaches these cases from a Critical Legal Studies perspective and analyzes the specific rhetoric used by the courts when discussing mental illness and its wider implications. In no case examined does the court argue that imputing mental illness is no longer defamatory, even if the statement in the majority of the cases was ultimately deemed non-actionable. The cases in which the imputation of mental illness constituted defamation per se focused on the impact the imputation had or could have had on the plaintiffs’ careers or employment. This suggests that a plaintiff is more likely to be successful in a defamation claim
involving reputational harm to their abilities as an employee. A consistent standard for what constitutes non-actionable opinion is needed in order to understand the state of defamation law in relation to the imputation of mental illness. Courts also need to acknowledge their role in the country’s social context and the impact their characterization has.

description: The detection of the primordial B-mode polarization signal of the cosmic microwave background (CMB) would provide evidence for inflation. Yet as has become increasingly clear, the detection of a such a faint signal requires an instrument with both wide frequency coverage to reject foregrounds and excellent control over instrumental systematic effects. Using a polarizing Fourier transform spectrometer (FTS) for CMB observations meets both these requirements. In this work, we present an analysis of instrumental systematic effects in polarizing Fourier transform spectrometers, using the Primordial Inflation Explorer (PIXIE) as a worked example. We analytically solve for the most important systematic effects inherent to the FTS - emissive optical components, misaligned optical components, sampling and phase errors, and spin synchronous effects - and demonstrate that residual systematic error terms after corrections will all be at the sub-nK level, well below the predicted 100 nK B-mode signal.
