description: We study dc conductivity of a Weyl semimetal with uniaxial anisotropy (Fermi velocity ratio $ξ= v_\bot/v_\parallel\neq1$) considering the scattering of charge carriers by a wide class of impurity potentials, both short- and long-range. We obtain the ratio of transverse and longitudinal (with respect to the anisotropy axis) conductivities as a function of both $ξ$ and temperature. We find that the transverse and longitudinal conductivities exhibit different temperature dependence in the case of short-range disorder. For general long-range disorder, the temperature dependence ($\sim T^4$) of the conductivity turns out to be insensitive of the anisotropy in the limits of strong ($ξ\gg$ and $\ll1$) and weak ($ξ\approx1$) anisotropy.

description: [abridged] We investigate the coevolution of galaxies and hosted supermassive black holes throughout the history of the Universe by a statistical approach based on the continuity equation and the abundance matching technique. Specifically, we present analytical solutions of the continuity equation without source term to reconstruct the supermassive black hole (BH) mass function from the AGN luminosity functions. Such an approach includes physically-motivated AGN lightcurves tested on independent datasets, which describe the evolution of the Eddington ratio and radiative efficiency from slim- to thin-disc conditions. We nicely reproduce the local estimates of the BH mass function, the AGN duty cycle as a function of mass and redshift, along with the Eddington ratio function and the fraction of galaxies with given stellar mass hosting an AGN with given Eddington ratio. We exploit the same approach to reconstruct the observed stellar mass function at different redshift from the UV and far-IR luminosity functions associated to star formation in galaxies. These results imply that the buildup of stars and BHs in galaxies occurs via in-situ processes, with dry mergers playing a marginal role at least for stellar masses < 3 10^11 M_sun and BH masses < 10^9 M_sun, where the statistical data are more secure and less biased by systematic errors. In addition, we develop an improved abundance matching technique to link the stellar and BH content of galaxies to the gravitationally dominant dark matter component. The resulting relationships constitute a testbed for galaxy evolution models, highlighting the complementary role of stellar and AGN feedback in the star formation process. Finally, the clustering properties of BHs and galaxies are found to be in full agreement with current observations, so further validating our results from the continuity equation.

description: In this paper we develop a numerical method for efficiently approximating solutions of certain Zakai equations in high dimensions. The key idea is to transform a given Zakai SPDE into a PDE with random coefficients. We show that under suitable regularity assumptions on the coefficients of the Zakai equation, the corresponding random PDE admits a solution random field which, for almost all realizations of the random coefficients, can be written as a classical solution of a linear parabolic PDE. This makes it possible to apply the Feynman--Kac formula to obtain an efficient Monte Carlo scheme for computing approximate solutions of Zakai equations. The approach achieves good results in up to 25 dimensions with fast run times.
title: An unstructured Finite-Volume Level Set / Front Tracking method for capillary flows
Creators: name: Tolle, Tobias
Publisher: name: UNSPECIFIED
Year: 2023

description: In this thesis the unstructured Finite-Volume hybrid Level Set / Front Tracking method (LENT) for immiscible two-phase flows is extended to enable the simulation of capillary flows. The major contributions are a more accurate interface curvature approximation, an accuracy driven pressure velocity coupling algorithm, an approximation technique for consistent mass fluxes for momentum convection and two novel approaches for the computation of volume fractions from triangulated surfaces. All proposed techniques and algorithms are devised for unstructured Finite-Volume meshes. The improved curvature approximation uses a signed distance field as input and utilizes surface-mesh/volume-mesh mappings to reduce curvature variation in interface normal direction. A novel, local correction approach is introduced to further reduce the curvature error in cells intersected by the interface. To ensure a prescribed solution accuracy, an iterative, accuracy driven pressure velocity coupling algorithm is presented that builds on the established segregated solution algorithms. The necessity of consistent mass fluxes for momentum convection in the presence of differing fluid densities is analyzed. For interface advection methods that do not utilize phase-specific volumetric fluxes, a method to obtain approximate, consistent mass fluxes is proposed. The resulting improvements for capillary flows are demonstrated using canonical verification and validation test cases. Two novel algorithms to compute volume fractions on unstructured volume meshes from oriented triangle surfaces meshes are introduced, one based on geometric intersections and one based on approximation and adaptive refinement. Intended for the phase indicator calculation in the context of Level Set / Front Tracking methods, both algorithms are shown to be sufficiently accurate to initialize volume fractions also for the Volume-of-Fluid method. In fact, test cases demonstrate that both approaches’ accuracy is only limited by the resolution of the surface mesh.
HOW MAINSTREAMING AND MULTILEVEL GOVERNANCE STRUCTURES EMPOWER PLACE-BASED APPROACHES TO REFUGEE INTEGRATION: THE CASE OF ALTENA, GERMANY
Creators: name: Strang, Alexis V.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: This thesis explores the importance of strong place-based techniques for refugee integration. The integration of refugees, when understood as a two-way process between the host community and refugees, is vital in moving away from dehumanized, national level representations, towards a more realistic view of refugees as individuals who are attempting to live and belong in their new communities. The German system mainstreams integration efforts at the national level by formulating policies of education, health care, and employment for the population as a whole (rather than specifically for refugees as a group). This system empowers towns and municipalities to apply more targeted, effective approaches to integration that fit the specific needs of their communities. Multilevel governance structures also aid in the ability of local level governments to apply targeted integration approaches, as they prevent potentially ill-fitting top-down initiatives from disrupting place-based measures. This thesis examines Altena, a German town known for its progressive integration techniques, through secondary sources and interviews with the mayor and integration team. Their efforts include valuing practicality over formality; emphasizing communication between civil society, the local government, and refugees; creating open, accessible social spaces; and conducting integration initiatives with the spirit of moral responsibility. Ultimately, this thesis examines how processes of multilevel governance and mainstreaming empower the local level to create policies and programs that promote more targeted forms of integration. From Altena, we learn just how valuable this relative autonomy is for the local level.

description: PDDLStream solvers have recently emerged as viable solutions for Task and Motion Planning (TAMP) problems, extending PDDL to problems with continuous action spaces. Prior work has shown how PDDLStream problems can be reduced to a sequence of PDDL planning problems, which can then be solved using off-the-shelf planners. However, this approach can suffer from long runtimes. In this paper we propose LAZY, a solver for PDDLStream problems that maintains a single integrated search over action skeletons, which gets progressively more geometrically informed, as samples of possible motions are lazily drawn during motion planning. We explore how learned models of goal-directed policies and current motion sampling data can be incorporated in LAZY to adaptively guide the task planner. We show that this leads to significant speed-ups in the search for a feasible solution evaluated over unseen test environments of varying numbers of objects, goals, and initial conditions. We evaluate our TAMP approach by comparing to existing solvers for PDDLStream problems on a range of simulated 7DoF rearrangement/manipulation problems.

description: We combine rational homotopy theory and higher Lie theory to describe the WZW term in the M5-brane sigma model. We observe that this term admits a natural interpretation as a twisted 7-cocycle on super-Minkowski spacetime with coefficients in the rational 4-sphere. This exhibits the WZW term as an element in twisted cohomology, with the twist given by the cocycle of the M2-brane. We consider integration of this rational situation to differential cohomology and differential cohomotopy.

We give evidence for these conjectures, and discuss their relationship to previous work. We generalise one of these conjectures to the case of connected reductive groups which are unramified over Q_p, and we also generalise the second author's previous conjecture for GL(n)/Q to this setting, and show that the two conjectures are generically in agreement.

description: We present the analysis of the entire HARPS observations of three stars that host planetary systems: HD1461, HD40307, and HD204313. The data set spans eight years and contains more than 200 nightly averaged velocity measurements for each star. This means that it is sensitive to both long-period and low-mass planets and also to the effects induced by stellar activity cycles. We modelled the data using Keplerian functions that correspond to planetary candidates and included the short- and long-term effects of magnetic activity. A Bayesian approach was taken both for the data modelling, which allowed us to include information from activity proxies such as $\log{(R'_{\rm HK})}$ in the velocity modelling, and for the model selection, which permitted determining the number of significant signals in the system. The Bayesian model comparison overcomes the limitations inherent to the traditional periodogram analysis. We report an additional super-Earth planet in the HD1461 system. Four out of the six planets previously reported for HD40307 are confirmed and characterised. We discuss the remaining two proposed signals. In particular, we show that when the systematic uncertainty associated with the techniques for estimating model probabilities are taken into account, the current data are not conclusive concerning the existence of the habitable-zone candidate HD40307 g. We also fully characterise the Neptune-mass planet that orbits HD204313 in 34.9 days.

description: As techniques for fault-tolerant quantum computation keep improving, it is natural to ask: what is the fundamental lower bound on redundancy? In this paper, we obtain a lower bound on the redundancy required for $ε$-accurate implementation of a large class of operations that includes unitary operators. For the practically relevant case of sub-exponential depth and sub-linear gate size, our bound on redundancy is tighter than the known lower bounds. We obtain this bound by connecting fault-tolerant computation with a set of finite blocklength quantum communication problems whose accuracy requirements satisfy a joint constraint. The lower bound on redundancy obtained here leads to a strictly smaller upper bound on the noise threshold for non-degradable noise. Our bound directly extends to the case where noise at the outputs of a gate are non-i.i.d. but noise across gates are i.i.d.

Search for $t\bar tH/A \rightarrow t\bar tt\bar t$ production in the multilepton final state in proton-proton collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector

description: A search for a new heavy scalar or pseudo-scalar Higgs boson ($H/A$) produced in association with a pair of top quarks, with the Higgs boson decaying into a pair of top quarks ($H/A\rightarrow t\bar{t}$) is reported. The search targets a final state with exactly two leptons with same-sign electric charges or at least three leptons. The analysed dataset corresponds to an integrated luminosity of 139 fb$^{-1}$ of proton-proton collisions collected at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC. Two multivariate classifiers are used to separate the signal from the background. No significant excess of events over the Standard Model expectation is observed. The results are interpreted in the context of a type-II two-Higgs-doublet model. The observed (expected) upper limits at 95% confidence level on the $t\bar{t}H/A$ production cross-section times the branching ratio of $H/A\rightarrow t\bar{t}$ range between 14 (10) fb and 6 (5) fb for a heavy Higgs boson with mass between 400 GeV and 1000 GeV, respectively. Assuming that only one particle, either the scalar $H$ or the pseudo-scalar $A$, contributes to the $t\bar{t}t\bar{t}$ final state, values of $\tanβ$ below 1.2 or 0.5 are excluded for a mass of 400 GeV or 1000 GeV, respectively. These exclusion ranges increase to $\tanβ$ below 1.6 or 0.6 when both particles are considered.

description: We introduce an algorithm that constructs disordered mass-spring networks whose elastic properties mimic that of glasses by tuning the fluctuations of the local elastic properties, keeping fixed connectivity and controlling the prestress. In two dimensions, the algorithm reproduces the dependence of gasses' vibrational properties, such as quasi-localised vibrational modes and Boson peak, on the degree of stability. The sound attenuation displays Rayleigh scattering and disorder-broadening regimes at different frequencies, and the attenuation rate increases with increased stability. Our results establish a strong connection between the vibrational features of disordered solids and the fluctuations of the local elastic properties and provide a new approach to investigating glasses' vibrational anomalies.

description: Ultracold gases promise many applications in quantum metrology, simulation and computation. In this context, optimal control theory (OCT) provides a versatile framework for the efficient preparation of complex quantum states. However, due to the high computational cost, OCT of ultracold gases has so far mostly been applied to one-dimensional (1D) problems. Here, we realize computationally efficient OCT of the Gross-Pitaevskii equation (GPE) to manipulate Bose-Einstein condensates in all three spatial dimensions. We study various realistic experimental applications where 1D simulations can only be applied approximately or not at all. Moreover, we provide a stringent mathematical footing for our scheme and carefully study the creation of elementary excitations and their minimization using multiple control parameters. The results are directly applicable to recent experiments and might thus be of immediate use in the ongoing effort to employ the properties of the quantum world for technological applications.

description: Quantum-enhanced data science, also known as quantum machine learning (QML), is of growing interest as an application of near-term quantum computers. Variational QML algorithms have the potential to solve practical problems on real hardware, particularly when involving quantum data. However, training these algorithms can be challenging and calls for tailored optimization procedures. Specifically, QML applications can require a large shot-count overhead due to the large datasets involved. In this work, we advocate for simultaneous random sampling over both the dataset as well as the measurement operators that define the loss function. We consider a highly general loss function that encompasses many QML applications, and we show how to construct an unbiased estimator of its gradient. This allows us to propose a shot-frugal gradient descent optimizer called Refoqus (REsource Frugal Optimizer for QUantum Stochastic gradient descent). Our numerics indicate that Refoqus can save several orders of magnitude in shot cost, even relative to optimizers that sample over measurement operators alone.

DETECTION OF CARIES ADJACENT TO TOOTH COLORED PROXIMAL RESTORATIONS USING STATIONARY INTRAORAL TOMOSYNTHESIS
Creators: name: Hilton, Robert
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Objectives: Caries adjacent to restorations (CAR) is the most common reason for replacing restorations.  This study compared the ability of stationary intraoral tomosynthesis (s-IOT) and conventional bitewing radiographs in detecting CAR.  Methods: Extracted teeth (N=77) with 113 proximal tooth-colored restorations were used.  Observers (N=7) utilized a 5-point scale to rate their confidence that CAR was present and stereomicroscopy was used to establish ground truth.  Results: S-IOT had a statistically higher (ANOVA p<0.05) ROC Az (0.72) than conventional radiographs (0.68).  S-IOT and conventional radiographs had a sensitivity of 0.48 and 0.44, respectively; the difference was statistically significant (ANOVA p<0.05). Specificity was 0.57 and 0.61, respectively, which difference was not statistically significant (ANOVA p>0.05). Conclusion: S-IOT showed higher diagnostic accuracy and sensitivity than conventional bitewing radiographs for detecting caries around proximal composite restorations.  While the clinical effect size is small, s-IOT is a promising imaging modality for advancing the detection of CAR.

description: The transition between distinct phases of matter is characterized by the nature of fluctuations near the critical point. We demonstrate that noise spectroscopy can not only diagnose the presence of a phase transition, but can also determine fundamental properties of its criticality. In particular, by analyzing a scaling collapse of the decoherence profile, one can directly extract the critical exponents of the transition and identify its universality class. Our approach naturally captures the presence of conservation laws and distinguishes between classical and quantum phase transitions. In the context of quantum magnetism, our proposal complements existing techniques and provides a novel toolset optimized for interrogating two-dimensional magnetic materials.

An Empirical Approach to the Extraction Versus Non-extraction Decision in Orthodontics
Creators: name: Zaytoun, Mary Lanier
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: The extraction versus non-extraction decision is one of the most heavily debated topics in orthodontics. We hypothesize that orthodontic treatment planning can be enhanced by creating an empirical, evidence-based tool to aid in making this decision. To this end, we identified thresholds of overjet, overbite, and crowding that empirically determine whether or not to extract. The thresholds were combined into two prediction models: a decision tree and a logistic regression equation. These pilot models demonstrated clinical viability when tested against four borderline cases. To further improve these models, four additional models were built utilizing machine learning algorithms and an increased number of variables that influence the extraction decision, including demographics, additional clinical values, and cephalometric analysis. The best preforming model, with 81% prediction accuracy, was the convolutional neural network, which included 113 input variables. With continued development these models have potential for valuable clinical utility in the orthodontic profession.

description: The exchange bias (EB) effect has been observed in magnetic Bi$_{0.9}$Gd$_{0.1}$Fe$_{0.9}$Ti$_{0.1}$O$_3$ nanoparticles. The influence of magnetic field cooling on the exchange bias effect has also been investigated. The magnitude of the exchange bias field ($H_{EB}$) increases with the cooling magnetic field, showing that the strength of the exchange bias effect is tunable by the field cooling. The $H_{EB}$ values are also found to be dependent on the temperature. This magnetically tunable exchange bias obtained at temperatures up to 250 K in Bi$_{0.9}$Gd$_{0.1}$Fe$_{0.9}$Ti$_{0.1}$O$_3$ nanoparticles may be worthwhile for potential applications.

description: atgn 13: The effect of practice on group information on the reliance on group information in the judgment of individuals. The goal of this project is to test whether practice in using group information to judge individuals increases the effect of group membership on the automatic and deliberate judgment of individuals from that group, even when there is individuating judgment-relevant information about these individuals.
“BLACK ATLANTA”: MUSICAL COUNTERNARRATIVES OF “AUTHENTIC” BLACKNESS IN DONALD GLOVER’S ATLANTA
Creators: name: Terry, Sierriana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: What does it mean to be black in the post-Obama era? Donald Glover’s television series      Atlanta can be seen as an attempt to answer this question, but for whom? Atlanta represents a      farcical approach to confronting the policed-hegemonic ideology behind the ideas and      conceptions of “authentic blackness” both sonically and visually. I argue that Atlanta’s visual      exploration of blackness and satirical critiques of U.S. black life, coupled with its extensive use      of U.S. black popular music (especially Atlanta-based hip-hop), produces a black soundscape      that counters and deconstructs policed ideologies of “authentic” black culture. Using the      proposed methodological frameworks of the post-soul aesthetic, black post-blackness, and      troubling vision, I will examine how Atlanta provides its audience with an understanding and      view of the world from a black perspective.
A Tale of Two Graphs: Freezing and Denoising Graph Structures for Multimodal Recommendation

description: Multimodal recommender systems utilizing multimodal features (e.g., images and textual descriptions) typically show better recommendation accuracy than general recommendation models based solely on user-item interactions. Generally, prior work fuses multimodal features into item ID embeddings to enrich item representations, thus failing to capture the latent semantic item-item structures. In this context, LATTICE proposes to learn the latent structure between items explicitly and achieves state-of-the-art performance for multimodal recommendations. However, we argue the latent graph structure learning of LATTICE is both inefficient and unnecessary. Experimentally, we demonstrate that freezing its item-item structure before training can also achieve competitive performance. Based on this finding, we propose a simple yet effective model, dubbed as FREEDOM, that FREEzes the item-item graph and DenOises the user-item interaction graph simultaneously for Multimodal recommendation. Theoretically, we examine the design of FREEDOM through a graph spectral perspective and demonstrate that it possesses a tighter upper bound on the graph spectrum. In denoising the user-item interaction graph, we devise a degree-sensitive edge pruning method, which rejects possibly noisy edges with a high probability when sampling the graph. We evaluate the proposed model on three real-world datasets and show that FREEDOM can significantly outperform current strongest baselines. Compared with LATTICE, FREEDOM achieves an average improvement of 19.07% in recommendation accuracy while reducing its memory cost up to 6$\times$ on large graphs.

description: Noncommutative geometric construction of gravity in the two sheeted spacetime can be viewed as a discretized version of a Kaluza-Klein theory. In this paper, we show that it is possible to incorporate the nonabelian gauge fields in the same framework. The generalized Hilbert-Einstein action is gauge invariant only in two cases. In the first case, the gauge group must be abelian on one sheet of spacetime and nonabelian on the other one. In the second case, the gauge group must be the same on two sheets of spacetime. Actually, the theories of electroweak and strong interactions are exactly these two cases.

description: You have some RNA-Seq samples and want to know what's in them? You urgently need to get these RNA-Seq results but your resident bioinformatician is on vacation — again? You have an extensive SRA query with hundreds of libraries to analyze and you don't know where to start? If any of those questions sound familiar, check out ZARP!

ZARP is a generic RNA-Seq analysis pipeline that allows you to analyze your Illumina short-read sequencing libraries without a lot of bioinformatics experience. ZARP preprocesses (Cutadapt), aligns (STAR), quantifies (kallisto, Salmon) and annotates (ALFA) your sequencing reads, runs quality control (FASTQC, TIN scores) and a principal component analysis on your samples, and produces a report with (mostly) interactive visualizations (MultiQC). ZARP is written in Snakemake, is reasonably fast and not very resource-hungry.

To make it easy to ZARP your samples, we provide ZARP-cli, a convenient command-line interface for starting ZARP runs. ZARP-cli downloads libraries straight from SRA and manages genome resources as well as your default settings, allowing you to trigger ZARP very quickly after initial setup. ZARP-cli also infers missing metadata required for the analysis (read orientation, adapter sequences or even the source organism) from the data itself, which is very useful for meta-analyses or those cases where the person who prepared the original library is now the CEO of a unicorn (good for them!) and doesn’t respond to your insignificant emails and all their notebooks burned to ashes in that fire last year.

Leave your (ex-) colleagues to their deserved holidays and/or new challenges and just ZARP your samples!
Identifying lens spaces in polynomial time

description: We show that if a closed, oriented 3-manifold M is promised to be homeomorphic to a lens space L(n,k) with n and k unknown, then we can compute both n and k in polynomial time in the size of the triangulation of M. The tricky part is the parameter k. The idea of the algorithm is to calculate Reidemeister torsion using numerical analysis over the complex numbers, rather than working directly in a cyclotomic field.

description: When an emitter ensemble interacts with the electromagnetic field, dipole-dipole interactions are induced between the emitters. The magnitude and shape of these interactions are fully determined by the specific form of the electromagnetic field modes. If the emitters are placed in the vicinity of a nanophotonic waveguide, such as a cylindrical nanofiber, the complex functional form of these modes makes the analytical evaluation of the dipole-dipole interaction cumbersome and numerically costly. In this work, we provide a full detailed description of how to successfully calculate these interactions, outlining a method that can be easily extended to other environments and boundary conditions. Such exact evaluation is of importance as, due to the collective character of the interactions and dissipation in this kind of systems, any small modification of the interactions may lead to dramatic changes in experimental observables, particularly as the number of emitters increases. We illustrate this by calculating the transmission signal of the light guided by a cylindrical nanofiber in the presence of a nearby chain of emitters.

description: Researchers looking for data across language archives often rely on harvesters such as OLAC or VLO. In this search, they are dependent on mappings of metadata categories across archives. While conducting a survey of metadata standards and landing pages of a number of DELAMAN archives, we came across problems with the notion that entering a search term in a unifying search box will reliably turn out all relevant available data, nothing less, nothing more. However, different types of vagueness in the metadata distort this picture. Taking “language”, the probably most relevant metadata category for linguists as an example, it becomes clear that it can refer to at least two categories: In some cases, it describes the content language, in others the languages of the actor(s) in the recording, in yet others it may be the language that is used to translate the resource. In our talk, we identify different types of vagueness: vagueness of the metadata category itself, values entered can be poorly defined, values can be overlapping, the relation of the metadata category to the resource can be unclear (e.g. does the date describe the publication date, the recording date, the date of metadata creation, the duration of a documentation project?). We show how vagueness impacts findability of resources and reliability of search results. We attempt to sketch possible solutions for some types of vagueness and discuss whether we just have to live with this vagueness in our metadata descriptions.

Effect of bracket type and wire dimension on orthodontic alignment: An analysis using 3D imaging
Creators: name: Piers, Christian
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Many different brackets and archwires exist to align the teeth in orthodontics.  We hypothesized that alignment efficiency is affected by wire dimension, bracket type and jaw.  Accordingly, two clinical trials were conducted to compare: 1) customized to non-customized brackets; and 2) conventional brackets to self-ligating brackets in a customized system.  Subjects were randomized to either .014” or .016” archwires.  Intraoral scans were obtained at 3 time points and 3-way ANOVA was performed.  In .016” wires, the mean reduction in malalignment in the customized group (mean=3.2mm, SD=1.9mm) was greater than that of the non-customized group (mean=2.2mm, SD=1.4mm) from 0-6 weeks (p=0.025).  Conventional brackets were more efficient than self-ligating brackets from 6-12 weeks (p=.014).  However, there were no significant differences in overall alleviation of malalignment based on bracket type, wire dimension, or jaw (p>.05).  This suggests the increased cost of customized and self-ligating brackets may not be justified by increased alignment efficiency.
