description: We study the effect of anisotropy of the Rashba coupling on the extrinsic spin Hall effect due to spin-orbit active adatoms on graphene. In addition to the intrinsic spin-orbit coupling, a generalized anisotropic Rashba coupling arising from the breakdown of both mirror and hexagonal symmetries of pristine graphene is considered. We find that Rashba anisotropy can strongly modify the dependence of the spin Hall angle on carrier concentration. Our model provides a simple and general description of the skew scattering mechanism due to the spin-orbit coupling that is induced by proximity to large adatom clusters.

Creating Personalized Synthetic Voices from Post-Glossectomy Speech with Guided Diffusion Models

description: This paper is about developing personalized speech synthesis systems with recordings of mildly impaired speech. In particular, we consider consonant and vowel alterations resulted from partial glossectomy, the surgical removal of part of the tongue. The aim is to restore articulation in the synthesized speech and maximally preserve the target speaker's individuality. We propose to tackle the problem with guided diffusion models. Specifically, a diffusion-based speech synthesis model is trained on original recordings, to capture and preserve the target speaker's original articulation style. When using the model for inference, a separately trained phone classifier will guide the synthesis process towards proper articulation. Objective and subjective evaluation results show that the proposed method substantially improves articulation in the synthesized speech over original recordings, and preserves more of the target speaker's individuality than a voice conversion baseline.

description: Data from social media are providing unprecedented opportunities to investigate the processes that rule the dynamics of collective social phenomena. Here, we consider an information theoretical approach to define and measure the temporal and structural signatures typical of collective social events as they arise and gain prominence. We use the symbolic transfer entropy analysis of micro-blogging time series to extract directed networks of influence among geolocalized sub-units in social systems. This methodology captures the emergence of system-level dynamics close to the onset of socially relevant collective phenomena. The framework is validated against a detailed empirical analysis of five case studies. In particular, we identify a change in the characteristic time-scale of the information transfer that flags the onset of information-driven collective phenomena. Furthermore, our approach identifies an order-disorder transition in the directed network of influence between social sub-units. In the absence of a clear exogenous driving, social collective phenomena can be represented as endogenously-driven structural transitions of the information transfer network. This study provides results that can help define models and predictive algorithms for the analysis of societal events based on open source data.

description: We address the problem of noise and interference corrupted channel estimation in massive MIMO systems. Interference, which originates from pilot reuse (or contamination), can in principle be discriminated on the basis of the distributions of path angles and amplitudes. In this paper we propose novel robust channel estimation algorithms exploiting path diversity in both angle and power domains, relying on a suitable combination of the spatial filtering and amplitude based projection. The proposed approaches are able to cope with a wide range of system and topology scenarios, including those where, unlike in previous works, interference channel may overlap with desired channels in terms of multipath angles of arrival or exceed them in terms of received power. In particular we establish analytically the conditions under which the proposed channel estimator is fully decontaminated. Simulation results confirm the overall system gains when using the new methods.

description: We develop an invariant local theory of Lorentz surfaces in pseudo-Euclidean 4-space by use of a linear map of Weingarten type. We find a geometrically determined moving frame field at each point of the surface and obtain a system of geometric functions. We prove a fundamental existence and uniqueness theorem in terms of these functions. On any Lorentz surface with parallel normalized mean curvature vector field we introduce special geometric (canonical) parameters and prove that any such surface is determined up to a rigid motion by three invariant functions satisfying three natural partial differential equations. In this way we minimize the number of functions and the number of partial differential equations determining the surface, which solves the Lund-Regge problem for this class of surfaces.

Generation and complete nondestructive analysis of hyperentanglement assisted by nitrogen-vacancy centers in resonators

description: We present two efficient schemes for the deterministic generation and the complete nondestructive analysis of hyperentangled Bell states in both the polarization and spatial-mode degrees of freedom (DOFs) of two-photon systems, assisted by the nitrogen-vacancy (NV) centers in diamonds coupled to microtoroidal resonators as a result of cavity quantum electrodynamics (QED). With the input-output process of photons, two-photon polarization-spatial hyperentangled Bell states can be generated in a deterministic way and their complete nondestructive analysis can be achieved. These schemes can be generalized to generate and analyze hyperentangled Greenberger-Horne-Zeilinger states of multi-photon systems as well. Compared with previous works, these two schemes relax the difficulty of their implementation in experiment as it is not difficult to obtain the $π$ phase shift in single-sided NV-cavity systems. Moreover, our schemes do not require that the transmission for the uncoupled cavity is balanceable with the reflectance for the coupled cavity. Our calculations show that these schemes can reach a high fidelity and efficiency with current technology, which may be a benefit to long-distance high-capacity quantum communication with two DOFs of photon systems.

description: Time-dependent equation-of-motion coupled cluster (TD-EOM-CC) is used to simulate impulsive stimulated x-ray Raman scattering (ISXRS) of ultrashort laser pulses by neon, carbon monoxide, pyrrole, and p-aminophenol. The TD-EOM-CC equations are expressed in the basis of field-free EOM-CC states, where the calculation of the core-excited states is simplified through the use of the core-valence separation (CVS) approximation. The transfer of electronic population from the ground state to the core- and valence-excited states is calculated for different numbers of included core- and valence-excited states, as well as for electric field pulses with different polarizations and carrier frequencies. The results indicate that Gaussian pulses can transfer significant electronic populations to the valence states through the Raman process. The sensitivity of this population transfer to the model parameters is analyzed. The time-dependent electronic density for p-aminophenol is also showcased, supporting the interpretation that ISXRS involves localized core excitations and can be used to rapidly generate valence wavepackets.

description: We prove that the hierarchy of higher antibrackets (aka higher Koszul brackets, aka Koszul braces) of a linear operator $Δ$ on a commutative superalgebra can be defined by some universal formulas involving iterated Nijenhuis-Richardson brackets having as arguments $Δ$ and the multiplication operators. As a byproduct, we can immediately extend higher antibrackets to noncommutative algebras in a way preserving the validity of generalized Jacobi identities.

description: The Illinois Data Bank was established in 2016 as an institutional file-based repository for research data (Hetrick et al. 2018). The service commits to a minimum retention period of five years, after which deposits are to be appraised and potentially reformatted, enhanced, or withdrawn. Preservation review guidelines were established and a “review indicator” was proposed (Anderson et al., 2016) to help curators identify datasets for which an in-depth, human-mediated review may be warranted. Our poster will characterize the datasets deposited during Illinois Data Bank’s first two years in order to evaluate the following: the feasibility and utility of our proposed Review Indicator as currently formulated, and possible actions during initial curation that would minimize or eliminate the need for a five-year review of some datasets. As we continue to explore strategies to assist with the on-going stewardship of complex data collections, we hope that our efforts will spark conversations with, and insights from, others who are responsible for preserving similarly challenging collections

description: Strong sustainability, according to the common definition, requires that different natural and economic capital stocks have to be maintained as physical quantities separately. Yet, in a world of uncertainty this cannot be guaranteed. To therefore define strong sustainability under uncertainty in an operational manner, we propose to use the concept of viability. Viability means that the different components and functions of a dynamic, stochastic system at any time remain in a domain where the future existence of these components and functions is guaranteed with sufficiently high probability. We develop a unifying and general ecological-economic concept of viability that encompasses the traditional ecological and economic notions of viability as special cases. It provides an operational criterion of strong sustainability under conditions of uncertainty. We illustrate this concept and demonstrate its usefulness by applying it to livestock grazing management in semi-arid rangelands.

description: The normal state in the hole underdoped copper oxide superconductors has proven to be a source of mystery for decades. The measurement of a small Fermi surface by quantum oscillations on suppression of superconductivity by high applied magnetic fields, together with complementary spectroscopic measurements in the hole underdoped copper oxide superconductors, point to a nodal electron pocket from charge order in YBa2Cu3O6+x. Here we report quantum oscillation measurements in the closely related stoichiometric material YBa2Cu4O8, which reveal similar Fermi surface properties to YBa2Cu3O6+x, despite an absence of charge order signatures in the same spectroscopic techniques such as x-ray diffraction that revealed signatures of charge order in YBa2Cu3O6+x. Fermi surface reconstruction in YBa2Cu4O8 is suggested to occur from magnetic field enhancement of charge order that is rendered fragile in zero magnetic fields because of its potential unconventional symmetry, and/or its occurrence as a subsidiary to more robust underlying electronic correlations.

"A couple of pretty tough cowboys": John Grady Cole and the Violence of the Border in All the Pretty Horses
Creators: name: Davis, Esther
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: With the 1992 release of his novel All the Pretty Horses, Cormac
McCarthy launched into fame, especially after the novel won him both the
National Book Award for Fiction and the National Book Critics Circle Award for
Fiction (“All the Pretty Horses”). The month before the novel’s release in May,
Richard B. Woodward noted in The New York Times that none of McCarthy’s
novels had “sold more than 5,000 copies in hardcover – which changed with All
the Pretty Horses, a national bestseller in the United States. The book was, 8
years after its initial publication, turned into a popular movie, directed by Billy
Bob Thornton and starring Matt Damon and Penelope Cruz (“All the Pretty
Horses”). All the Pretty Horses garnered McCarthy international attention and
recognition as a great American author.
Lafcadio Hearn and his Evolutionary Eco-Ethics in the 21st Century: Travelling through the Uncanny Valley of Exoticism in Robotic and Ghostly Japan
Creators: name: Galanos, Vassilis
Publisher: name: Culture - Journal of Culture in Tourism, Art & Education
Year: 2023

description: The present paper has a twofold aim. It firstly, excavates and extends previous literature on the uniqueness of Lafcadio Hearn’s philosophy and in particular his part-Spencerian and part-Buddhist evolutionary ethics. Based on this framework, it argues for such a framework to be relevant for the examination of contemporary interdisciplinary challenges across psychological, environmental, and technological registers. This argument is assisted by the close examination of a case study in the ethical challenges posed in the fields of artificial intelligence, robotics, and digital privacy. Recent scholarship in these fields of increasing importance has observed a Western trend in importing Japanese/Shintoist values in their ethical scrutiny. The paper traces the history of this trend through the examples of three Western scholars whose frameworks pertain a Japanese-oriented approach. It further suggests the existence of a certain continuity in Japanese/Shintoist culture in highlighting the role of the eerie and the uncanny traced across the works of Hearn and those of roboticist Masahiro Mori, developer of the uncanny valley model. Synthesised, these observations lead the discussion towards recommendations for the establishment of a field for Hearn studies, which should aim, theoretically, at the better historical and philosophical understanding of Hearn’s work, and, practically, at the application of Hearn’s contributions to knowledge in contemporary universal challenges.

description: The digital preservation community has been without a code of ethics until this point. The National Library of New Zealand, in conjunction with the National and State Libraries of Australasia (NSLA), has developed a draft Code of Ethics for Digital Preservation. This code sets standards for the ethical behaviour of professionals in the community. It does so through highlighting and codifying our responsibilities to digital objects that have long-term value. It allows the community to have a degree of accountability through setting expectations. It acts as a statement of expectation for new members of the community, offering an introduction to who we are as a group and our responsibilities. The code is also an instrument of justification that can be referenced to support arguments for particular courses of action that are specific to the challenge addressed by digital preservation. Finally, the code offers a statement that the community is taking a step towards becoming a profession. The poster will introduce the draft code of ethics, giving context to the rationale behind its development and describing in detail the purpose and intent behind each of the principles. The poster will present the most recent draft of the code, taking account of feedback from the first stages of consultation.

No Ideal Victim: A Cross Racial and Cross Socioeconomic Analysis of Domestic Violence Arrest Policies
Creators: name: Roane, Alexus
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: This thesis examines how different domestic violence arrest policies influence the distribution of intimate partner violence (IPV)-related homicide cases when taking into account race and socioeconomic status. To answer my research questions, I conduct a mixed methods analysis using a 27-state sample from the Center for Disease Control (CDC)'s National Violent Death Reporting System between 2003-2015 alongside interview data that I collected from five relevant professionals in North Carolina. The results of the statistical analysis show a statistically significant relationship between race, socioeconomic status, and domestic violence arrest policies. Descriptive statistics show that black women and American Indian/Alaskan Native women are over represented amongst IPV-related homicide cases whereas white women and women are underrepresented within the sample. Additionally, women with less than or equal to a high school education are over represented within the sample whereas women with some college education or beyond are underrepresented. Findings of this study aim to create a more nuanced discussion around the effectiveness of domestic violence arrest policies with hopes of informing policy makers of ways in which they can create more effective interventionist policies for black women and poor women who experience domestic violence.

description: This poster outlines high-level findings of the international Digital Preservation Maturity, Resourcing, Policy and Strategy survey. The survey was created and run by the Digital Preservation at Oxford and Cambridge (DPOC) project, in collaboration with the Digital Preservation Coalition (DPC) in 2018. The purpose of the survey was to collect current information about the digital preservation maturity of organizations and their full-time equivalent (FTE) staffing resources dedicated to digital preservation activities, as well as how these FTEs are arranged. This is measured alongside organizations’ current digital preservation policy and strategy landscape. The intention is to provide up-to-date information (including the raw anonymized dataset) for organizations looking to build their own business cases and advocate for digital preservation programs.
Jet-dominated quiescent state in black hole X-ray binaries: the cases of A0620--00 and XTE J1118+480

description: The radiative mechanism of the black hole X-ray transients (BHXTs) in their quiescent states (defined as the 2-10 keV X-ray luminosity $\le 10^{34}{\rm \,erg\,s^{-1}}$) remains unclear. In this work, we investigate the quasi-simultaneous quiescent state spectrum (including radio, infrared, optical, ultraviolet and X-ray) of two BHXTs, A0620--00 and XTE J1118+480. We find that, these two sources can be well described by a coupled accretion -- jet model. More specifically, most of the emission (radio up-to infrared, and the X-ray waveband) comes from the collimated relativistic jet. Emission from hot accretion flow is totally insignificant, and it can only be observed in mid-infrared (the synchrotron peak). Emission from the outer cold disc is only evident in UV band. These results are consistent with our previous investigation on the quiescent state of V404 Cyg, and confirm that the quiescent state is jet-dominated.

description: This paper uses data from the German Socio-Economic Panel for the years 2000 to 2005 to study the earnings differential between self- and dependent employed German men. Constructing a counterfactual earnings distribution for the self-employed in dependent employment and using quantile regression decompositions we find that the earnings differential over the distribution cannot be explained by differences in endowments. Furthermore, low-earning self-employed could earn more in dependent employment. Finally, the observed earnings advantage for the self-employed at the top of the earnings distribution is not associated with higher returns to observable variables.

description: This poster describes our recent and ongoing efforts for fostering computational reproducibility for biomolecular nuclear magnetic resonance (bioNMR) data processing. We have designed and supported a custom workflow management system, called CONNJUR Workflow Builder (CWB), over the past decade. We have recently embedded data curation activities within the workflow construction and execution environment, using the PREMIS model for digital preservation as the basic template of a bioNMR processing workflow. In this poster, we describe extending this effort in a goal to produce reproducible provenance records from CWB. To achieve this goal, the bioNMR curation record is being abstracted to the task level in the hope that different software tools can be used for the same spectral reconstruction workflow. Results and limitations will be discussed.

Lastly, we provide a sufficient semantic condition describing when a similarly general soundness result is also available.

description: Out of the estimated few trillion galaxies, only around a million have been detected through radio frequencies, and only a tiny fraction, approximately a thousand, have been manually classified. We have addressed this disparity between labeled and unlabeled images of radio galaxies by employing a semi-supervised learning approach to classify them into the known Fanaroff-Riley Type I (FRI) and Type II (FRII) categories. A Group Equivariant Convolutional Neural Network (G-CNN) was used as an encoder of the state-of-the-art self-supervised methods SimCLR (A Simple Framework for Contrastive Learning of Visual Representations) and BYOL (Bootstrap Your Own Latent). The G-CNN preserves the equivariance for the Euclidean Group E(2), enabling it to effectively learn the representation of globally oriented feature maps. After representation learning, we trained a fully-connected classifier and fine-tuned the trained encoder with labeled data. Our findings demonstrate that our semi-supervised approach outperforms existing state-of-the-art methods across several metrics, including cluster quality, convergence rate, accuracy, precision, recall, and the F1-score. Moreover, statistical significance testing via a t-test revealed that our method surpasses the performance of a fully supervised G-CNN. This study emphasizes the importance of semi-supervised learning in radio galaxy classification, where labeled data are still scarce, but the prospects for discovery are immense.

description: This bachelor thesis deals with queer representation in the TEFL classroom. It focuses on queer representation in EFL materials and answers the question how representation of queer identities in EFL materials supports LGBTQIA+ inclusion in the EFL classroom. After discussing why queer inclusion is important and using queer theory as a theoretical framework, the findings are connected to the TEFL curriculum of Lower Saxony. Furthermore, the importance of queer inclusion specifically in the EFL context is explained and different ways of representation are discussed. Moreover, possibilities of implementation of queer inclusion are considered, an adequate queer representation is defined and 10 thematic anchors are developed to use as means of queer inclusion in the EFL classroom.
Does Experimentally Inducing Moods in Students Change Ratings of their Friends’ Behaviors?
Creators: name: Smith, Logan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Many factors, including affect, have been shown to have an effect on how an individual evaluates another person and subsequently rates them on a questionnaire. These discrepancies can impact diagnostic efforts because other raters, typically caregivers, are often the main source of information given about their children. I hypothesized that experimentally inducing happiness, sadness, and anger would cause a change in rating compared to a neutral control group such that the happy and sad groups would rate their friends more positively and the angry group would rate their friends more negatively. A random sample of emerging adults enrolled and completed a pretest about their best friend’s behaviors, which contained items from the Adult Behavior Checklist (ABCL), which measures various kinds of psychopathology. Participants were randomly assigned to different mood manipulations, which asked them to write about an interaction with their best friends that was happy, sad, angry, or neutral. Participants completed the entire ABCL as a posttest. I performed an analysis of covariance using the ABCL posttest as the dependent variable, the manipulation group as the independent variable, and the pretest as a covariate. I found a significant main effect of the manipulation and conducted multiple regression to investigate further. The results were nonsignificant for the happy and sad induction groups, but the anger group’s ratings differed significantly in the expected direction. Experimentally inducing different moods resulted in significantly different ratings by participants of their best friends. Clinicians should account for the outside rater’s mood when making decisions based on information given by that informant if their mood could alter results. Future research should investigate the effect of rater mood further and develop strategies to effectively integrate any discrepancies into the clinical decision-making process as useful information.

Lafcadio Hearn's pursuit of African - American culture in Cincinnati
Creators: name: Kemme, Steve
Publisher: name: Culture - Journal of Culture in Tourism, Art & Education
Year: 2023

description: During Lafcadio Hearn’s eight years in Cincinnati, he delved deeply into the culture and everyday lives of the African-Americans living in the city in the decade after the Civil War. He frequented the bars and dance halls patronized by them and wrote vivid newspaper stories free of racism about their singing, dancing, and impoverished lives. Many of the blacks were former slaves who had been liberated by the Union’s victory or had escaped before the war and had been ushered to freedom by the Underground Railroad. Bordering the slave state of Kentucky, Cincinnati had been an important station in that network. Hearn collected the lyrics of dozens of songs he heard in African-American entertainment venues and from black dockworkers along the riverfront levee. These stories about African-Americans contained some of Hearn’s best writing during this early stage in his career. His Cincinnati period marked the beginning of his lifelong interest in exploring different ethnic cultures, foreshadowing some of his writing in New Orleans, Martinique and Japan.

description: We consider the problem of growing multiplex networks with intrinsic fitness and inter-layer coupling. The model comprises two layers; one that incorporates fitness and another in which attachments are preferential. In the first layer, attachment probabilities are proportional to fitness values, and in the second layer, proportional to the sum of degrees in both layers. We provide analytical closed-form solutions for the joint distributions of fitness and degrees. We also derive closed-form expressions for the expected value of the degree as a function of fitness. The model alleviates two shortcomings that are present in the current models of growing multiplex networks: homogeneity of connections, and homogeneity of fitness. In this paper, we posit and analyze a growth model that is heterogeneous in both senses.

description: In this work we explore the one-dimensional extended Hubbard model as a fluid system modelling liquid phases of different densities. This model naturally displays two length scales of interaction, which are connected with waterlike anomalies. We analyze the density anomaly as a function of the model parameters, namely the hopping, on-site and first neighbor interactions. We show that this anomaly is present for a wide range of model parameters and is connected to a ground-state liquid-liquid critical point.

Rollenverständnis

description: Was brauchen Lehrkräfte, um gesund und leistungsfähig zu bleiben? Zunächst nur das, was leitende Manager oder ihre Fahrer auch brauchen: Einen pfleglichen Umgang mit ihrer Gesundheit, Identifikation mit ihren Aufgaben und passende Kompetenzen, realistische Ziele, lebenslange effektive Weiterbildung, um wechselnden Problemlagen gewachsen zu sein, vernünftige Arbeitsbedingungen an ihrem unmittelbaren Arbeitsplatz sowie im Konzern und eine politische Großwetterlage, die ihren Aufgaben und Zielen günstig ist. In allen Fällen ist der Faktor Mensch für die Freude am "Funktionieren" ebenso bedeutsam wie die herrschenden Rahmenbedingungen. Trotz aller Statistiken über Burnout und Frühpensionierung kann und soll der Lehrerberuf Freude und Sinnerfahrungen vermitteln (vgl. Grimm, 1996 und Sieland, 2000). Aber: Wer gesunde und leistungsfähige Pädagogen haben möchte, muss sich selbst gezielt dafür einsetzen und nicht nur dafür plädieren, dass andere aktiv werden, oder dass sich die Großwetterlage verbessern muss. Auf der Suche nach Ansätzen zur Förderung der Gesundheit und Leistungsfähigkeit von Lehrkräften möchte der Autor strukturierende Fragen formulieren, spezielle Forschungsergebnisse über Ressourcen und Risikofaktoren in der Lehrperson skizzieren und einen Orientierungsrahmen vorschlagen, der wenigstens zu Einzelaktionen ermutigt, solange die eigentlich notwendigen konzertierten Aktionen ausbleiben.

description: The thermoelectric properties of distorted bismuth (110) layer are investigated using first-principles calculations combined with the Boltzmann transport equation for both electrons and phonons. To accurately predict the electronic and transport properties, the quasiparticle corrections with the GW approximation of many-body effects have been explicitly included. It is found that a maximum ZT value of 6.4 can be achieved for n-type system, which is essentially stemmed from the weak scattering of electrons. Moreover, we demonstrate that the distorted Bi layer remains high ZT values at relatively broad regions of both temperature and carrier concentration. Our theoretical work emphasizes that the deformation potential constant characterizing the electron-phonon scattering strength is an important paradigm for searching high thermoelectric performance materials.
