description: In this study we explore the LHC's Run II potential to the discovery of heavy Majorana neutrinos, with luminosities between $30$ and $3000$ fb$^{-1}$ in the $l^{\pm}l^{\pm}j~j$ final state. Given that there exist many models for neutrino mass generation, even within the Type I seesaw framework, we use a simplified model approach and study two simple extensions to the Standard Model, one with a single heavy Majorana neutrino, singlet under the Standard Model gauge group, and a limiting case of the left-right symmetric model. We then extend the analysis to a future hadron collider running at $100$ TeV center of mass energies. This extrapolation in energy allows us to study the relative importance of the resonant production versus gauge boson fusion processes in the study of Majorana neutrinos at hadron colliders. We analyze and propose different search strategies designed to maximize the discovery potential in either the resonant production or the gauge boson fusion modes.

description: The possibility of earthquake prediction is one of the key open questions in modern geophysics. We propose an approach based on the analysis of common short-term candidate precursors (2 weeks to 3 months prior to strong earthquake) with the subsequent processing of brain activity signals generated in specific types of rats (kept in laboratory settings) who reportedly sense an impending earthquake few days prior to the event. We illustrate the identification of short-term precursors using the groundwater sodium-ion concentration data in the time frame from 2010 to 2014 (a major earthquake occurred on February 28, 2013), recorded at two different sites in the south-eastern part of the Kamchatka peninsula, Russia. The candidate precursors are observed as synchronized peaks in the nonstationarity factors, introduced within the flicker-noise spectroscopy framework for signal processing, for the high-frequency component of both time series. These peaks correspond to the local reorganizations of the underlying geophysical system that are believed to precede strong earthquakes. The rodent brain activity signals are selected as potential "immediate" (up to 2 weeks) deterministic precursors due to the recent scientific reports confirming that rodents sense imminent earthquakes and the population-genetic model of Kirshvink (2000) showing how a reliable genetic seismic escape response system may have developed over the period of several hundred million years in certain animals. The use of brain activity signals, such as electroencephalograms, in contrast to conventional abnormal animal behavior observations, enables one to apply the standard "input-sensor-response" approach to determine what input signals trigger specific seismic escape brain activity responses

Patient Perspectives on the Development of a Novel Mobile Health (mHealth) Application for Dietary Supplement Tracking and Reconciliation
Creators: name: Post, Elana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: 
Background: More than 170 million adults use dietary supplements (DSs) in the United States, which can have both benefit and harm to patient health. DS use is often poorly documented in the medical record and can pose health risks if not properly communicated with providers. Reasons for poor DS documentation include low disclosure rates, time constraints of clinical encounters, and providers’ failure to inquire about DS use. This study was conducted to assess patients’ views on the facilitators and barriers to using a mobile health (mHealth) application (app) to collect and share DS information with their healthcare providers.
Methods: Utilizing a theory-based conceptual model, we conducted seven patient focus groups (FGs) to assess opinions on DS safety, provider communication, comfort with technology use, and our proposed mHealth app. Patient views will inform the creation of an mHealth app to improve DS patient-provider communication and tracking and reconciliation in the electronic medical record (EMR).
Results: Overall, participants believe their DS information is inaccurately represented in the EMR leading to safety concerns and negatively impacting overall quality-of-care. Participants desired an app designed with: 1) Health Insurance Portability and Accountability Act (HIPAA)-compliance; 2) ease of use for a variety of technical efficacy levels; 3) access to reliable DS information, including a DS-drug interaction checker; 4) integration with the EMR.
Conclusion: An app to simplify and improve DS entry and reconciliation was of interest to patients, as long as it maintained health autonomy and privacy and possessed key valuable features.

description: This paper studies short-range order (SRO) in the semiconductor alloy (GaN)$_{1-x}$(ZnO)$_x$. Monte Carlo simulations performed on a density functional theory (DFT)-based cluster expansion model show that the heterovalent alloys exhibit strong SRO because of the energetic preference for the valence-matched nearest-neighbor Ga-N and Zn-O pairs. To represent the SRO-related structural correlations, we introduce the concept of Special Quasi-ordered Structure (SQoS). Subsequent DFT calculations reveal dramatic influence of SRO on the atomic, electronic and vibrational properties of the (GaN)$_{1-x}$(ZnO)$_x$ alloy. Due to the enhanced statistical presence of the energetically unfavored Zn-N bonds with the strong Zn3$d$-N2$p$ repulsion, the disordered alloys exhibit much larger lattice bowing and band-gap reduction than those of the short-range ordered alloys. Inclusion of lattice vibrations stabilizes the disordered alloy.

description: We report two theoretical discoveries for $\mathbb{Z}_2$-topological metals and semimetals. It is shown first that any dimensional $\mathbb{Z}_2$ Fermi surface is topologically equivalent to a Fermi point. Then the famous conventional no-go theorem, which was merely proven before for $\mathbb{Z}$ Fermi points in a periodic system without any discrete symmetry, is generalized to that the total topological charge is zero for all cases. Most remarkably, we find and prove an unconventional strong no-go theorem: all $\mathbb{Z}_2$ Fermi points have the same topological charge $ν_{\mathbb{Z}_2} =1$ or $0$ for periodic systems. Moreover, we also establish all six topological types of $\mathbb{Z}_2$ models for realistic physical dimensions.

Cardiac Cell-type Targeting and Infection Patterning of Eight Adeno-associated Virus (AAV) Serotypes
Creators: name: Phookan, Ranan

Year: 2021

description: Adeno-associated virus (AAV) is non-pathogenic and its various serotypes demonstrate a range of tissue tropism, making it an ideal vector candidate for targeted gene therapy. Although cardiac-specific AAVs have previously been identified, their specificity in targeting individual cell types within the heart is unknown. We sought to identify an AAV serotype that preferentially targets cardiac fibroblasts for the pointed delivery of cardiac reprogramming factors. We analyzed eight AAVs, including four newly engineered serotypes, for their cardiac cell-type targeting. Four were intravenously injected via the tail vein and four were directly injected into the heart chamber of three-month-old C57BL/6 mice. Each serotype was equipped with a GFP tag to serve as a reporter of virally transduced cells. Immunofluorescence co-staining for GFP and cell-type specific markers revealed targeting of cardiomyocytes only. We then characterized the differences in targeting efficiency and infection distribution in the heart tissue for the eight serotypes. Analysis indicated that GFP distribution varied significantly between intravenously administered AAVs, while directly injected AAVs showed strong GFP localization at the injection site. Next, we performed RNAscope in-situ hybridization to assess the mean RNA transcript copy number per cell and found serotype differences in RNA-level expression and protein-level expression of transduced genes. The data obtained from this study experimentally confirms the cell-type targeting specificity of cardiac AAVs in the heart. Serotype differences in infection efficiency, distribution, and transcript copy number will be informative for selecting the proper serotype for future experimental and therapeutic efforts in cardiac biology.

description: Several scholars and researchers have examined the lack of representation for Black people in the film and television industry. My thesis adds to this conversation through interviews with Black creators who have firsthand experience with the industry. Their contribution, combined with research, addresses why the lack of representation in Hollywood is so difficult to overcome, and how Black creators’ fit into effecting some change. I have interviewed six Black creators who occupy different levels in the industry. In my interviews, Black cinematographers, producers, and film crew members have echoed a concern for the lack of diversity in front of and behind the camera. Black creators’ experiences are impacted by the extremely small, extremely competitive pool of talent that is competing for a chance to impress predominantly white executive producers. This pool shrinks even further because of film executive’s tendency to overlook Black talent. The perspective of these Black creators must be included in the conversation because they are involved in a project from the ground up, looking at how projects are pitched and which ones go to production. Now more than ever, understanding how Black creators can influence and change the film and television industry is important.

description: The existence of genuinely non-geometric backgrounds, i.e. ones without geometric dual, is an important question in string theory. In this paper we examine this question from a sigma model perspective. First we construct a particular class of Courant algebroids as protobialgebroids with all types of geometric and non-geometric fluxes. For such structures we apply the mathematical result that any Courant algebroid gives rise to a 3D topological sigma model of the AKSZ type and we discuss the corresponding 2D field theories. It is found that these models are always geometric, even when both 2-form and 2-vector fields are neither vanishing nor inverse of one another. Taking a further step, we suggest an extended class of 3D sigma models, whose world volume is embedded in phase space, which allow for genuinely non-geometric backgrounds. Adopting the doubled formalism such models can be related to double field theory, albeit from a world sheet perspective.

description: Bayesian properties of the signed root likelihood ratio statistic are analysed. Conditions for first-order probability matching are derived by the examination of the Bayesian posterior and frequentist means of this statistic. Second-order matching conditions are shown to arise from matching of the Bayesian posterior and frequentist variances of a mean-adjusted version of the signed root statistic. Conditions for conditional probability matching in ancillary statistic models are derived and discussed.

Effects of surface interaction on c-di-GMP regulation in Clostridioides difficile
Creators: name: Tunau-Spencer, Khalid
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Clostridioides difficile is a bacterial pathogen that causes antibiotic-associated intestinal disease. The signaling molecule cyclic diguanylate monophosphate (c-di-GMP) regulates various physiological changes such as biofilm formation, motility, and cell differentiation in many bacterial species. In C. difficile, c-di-GMP regulates motility, colonization, and virulence. In many bacteria, an increase in c-di-GMP levels is associated with the transition from a motile to a sessile lifestyle. In the presence of an abiotic surface, bacteria organize themselves in a protective manner through biofilm formation and become sessile. Prior work suggested that C. difficile in a biofilm (i.e., surface-associated) have higher intracellular c-di-GMP levels than free-living planktonic bacteria. We hypothesized that C. difficile responds to growth on a surface by increasing c-di-GMP levels. To test this hypothesis, we used a plasmid where transcription of a red fluorescent reporter, mCherry, is regulated by an upstream riboswitch that allows for transcription of mCherry under high c-di-GMP levels. With this plasmid, we quantified the percentage of the bacterial population that fluoresce red, indicative of an increase in c-di-GMP levels, at different time points. In this study, we found that the percentage of fluorescent cells on a solid surface closely resembles those in a liquid medium during a 24-hour period, suggesting that the levels of c-di-GMP remained similar in both conditions. Further, variation of fluorescence intensity of individual bacteria, indicative of variable intracellular c-di-GMP level, was also similar under the conditions tested. Additional work is needed to determine whether surface growth leads to changes in c-di-GMP at alternative time points or with different surface composition.

description: We present a comprehensive study of spectroscopic radius measurements of twelve neutron stars obtained during thermonuclear bursts or in quiescence. We incorporate, for the first time, a large number of systematic uncertainties in the measurement of the apparent angular sizes, Eddington fluxes, and distances, in the composition of the interstellar medium, and in the flux calibration of X-ray detectors. We also take into account the results of recent theoretical calculations of rotational effects on neutron star radii, of atmospheric effects on surface spectra, and of relativistic corrections to the Eddington critical flux. We employ Bayesian statistical frameworks to obtain neutron star radii from the spectroscopic measurements as well as to infer the equation of state from the radius measurements. Combining these with the results of experiments in the vicinity of nuclear saturation density and the observations of ~2 Msun neutron stars, we place strong and quantitative constraints on the properties of the equation of state between approximately 2-8 times the nuclear saturation density. We find that around M=1.5 Msun, the preferred equation of state predicts radii between 10.1 - 11.1 km. When interpreting the pressure constraints in the context of high density equations of state based on interacting nucleons, our results suggest a relatively weak contribution of the three-body interaction potential.

CD8 T cells that lack the DNA demethylases TET2 and TET3 exhibit an  innate-like gene expression program

description: Mice that lack the DNA demethylases TET2 and TET3 in their T cells show proliferation of innate-like (memory) CD8 cells. These activated innate-like cells have effector properties that are critical in fighting viral infections and suppressing the expansion of tumor cells. However, the gene expression program and subsequent molecular mechanisms underlying this lineage-skewing were unknown. Flow cytometry analysis of TET2/TET3 double-knockout (DKO) CD8 cells in mice established that upregulation of the transcription factor Eomes results in innate-like CD8 programming. By utilizing RNA-sequencing and differential expression analysis, we compared the gene expression programs of TET2/TET3 DKO CD8 cells with both wild-type CD8 cells and innate-like CD8 cells that overexpress Eomes. We observed noticeable overlap in the significantly differentially expressed genes and enriched pathways between the DKO and EomesTG mice in comparison to controls. In addition, we determined the key pathways and gene ontologies that were overrepresented in the DKO mice. Our results suggest that Eomes overexpression and TET2/TET3 deletion in CD8 cells share similar molecular mechanisms of innate-like expansion. We also discovered that genes unique to the TET2/3 DKO mice were highly enriched in cancer-related pathways. Further research into specific dysregulated genes we discovered is needed to understand how this lineage-skewing takes place.

description: We propose a digital quantum simulator of non-Abelian pure-gauge models with a superconducting circuit setup. Within the framework of quantum link models, we build a minimal instance of a pure $SU(2)$ gauge theory, using triangular plaquettes involving geometric frustration. This realization is the least demanding, in terms of quantum simulation resources, of a non-Abelian gauge dynamics. We present two superconducting architectures that can host the quantum simulation, estimating the requirements needed to run possible experiments. The proposal establishes a path to the experimental simulation of non-Abelian physics with solid-state quantum platforms.

description: We briefly discuss some of the known and new properties of rotating geometries that are relevant to this work. We generalize the analytical method of superposition of fields, known for generating nonrotating solutions, and apply it to construct massless and massive rotating physical wormholes sourced by a source-free electromagnetic field and an exotic fluid both anisotropic. Their stress-energy tensors are presented in compact and general forms. For the massive rotating wormholes there exists a mass-charge constraint yielding almost no more dragging effects than ordinary stars. There are conical spirals through the throat along which no local negative energy densities are noticed for these rotating wormholes. This conclusion extends to nonrotating massive type I wormholes derived previously by the author that seem to be the first kind of nonrotating wormholes with this property. Based on the classification made in J. Cosmol. Astropart. Phys. 07 (2015) 037 [arXiv:1412.8282]: "Type I wormholes have their radial pressure dying out faster, as one moves away from the throat, than any other component of the stress-energy and thus violate the least the local energy conditions. In type II (resp. III) the radial and transverse pressures are asymptotically proportional and die out faster (resp. slower) than the energy density".

description: Minimum wages have long been the subject of extensive scholarly debate in the United States. Many economists have reached different conclusions on the effects of minimum wages, particularly with regard to unemployment and poverty. In this study, I explore the effects of local minimum wages in a sample of US cities and counties on three poverty-related variables: unemployment, food insecurity, and jail admissions. The analysis is split into two sections. The first, which is similar to prior minimum wage studies, measures the relationships between the minimum wage, in nominal dollars, and each of the dependent variables. The second section incorporates differences in local costs of living among the sampled cities and counties to see if the relative purchasing power of the minimum wages, or the “gap” between the minimum wage and cost of living, affects their associated outcomes. Many earlier studies have accounted for cost of living only by adjusting the minimum wages for inflation, but this method simply captures growth in the price level from a specified base year rather than differences in cost of living across locations in a given year. Using stepwise fixed effects regression analyses, I find that the nominal minimum wage is positively associated with unemployment and negatively associated with food insecurity and jail admissions in the most complete models. The “gap” between the minimum wage and cost of living has a positive relationship with unemployment and no significant relationship with food insecurity or jail admissions in the most complete models. I also find that an additional independent variable – welfare generosity – is another powerful determinant of well-being in several of the models.

description: Die vorliegende Arbeit befasst sich mit der Analyse, Auslegung und Optimierung, sowie deranschließenden Vermessung einer neuen Antriebstopologie, des „vollintegrierten Kleinspan-nungstreaktionsantriebs“. Der Antrieb besteht aus einem Drehfeldmotor, einem Wechselrichterund einer Batterie, die ohne Kabel miteinander verbunden sind. Dies wird erreicht, indem dieBatterie um den Motor angeordnet wird und die Platine des Wechselrichters den Motor mit derBatterie verbindet. In den Nuten des Stators befindet sich jeweils nur ein Leiter. Diese Leiterwerden auf der Seite der Antriebswelle des Motors elektrisch verbunden und weisen Ähnlich-keiten mit dem Kurzschlusskäfig eines Asynchronmotors auf. Auf der Wechselrichterplatineist für jeden Leiter eine Halbbrücke vorgesehen.Die Auslegung basiert sowohl auf analytischen als auch auf numerischen Ansätzen, die ineinem iterativen Prozess angeordnet sind. Ein Demonstrator wird an einem Prüfstand mit einerBelastungsmaschine getestet und validiert.
description: This work deals with the analysis, design, optimization, and subsequent measurement of a newdrive topology, the so-called “fully integrated low-voltage reaction drive”. The drive consistsof a field motor, an inverter, and a battery that are connected without cables. This is achievedby arranging the battery around the motor and connecting the inverter board to the motorand the battery. Each slot in the stator contains only one conductor. These conductors areelectrically connected on the side of the motor’s drive shaft and resemble the squirrel cage inan asynchronous motor. A half-bridge is provided for each conductor on the inverter board.The design is based on both analytical and numerical approaches, which are organized in aniterative process. A demonstrator is tested and validated on a test bench with a load machine.

description: The ability of cells to manage consequences of exogenous proteotoxicity is key to cellular homeostasis. While a plethora of well-characterised machinery aids intracellular proteostasis, mechanisms involved in the response to denaturation of extracellular proteins remain elusive. Here we show that aggregation of protein ectodomains triggers their endocytosis via a macroendocytic route, and subsequent lysosomal degradation. Using ERBB2/HER2-specific antibodies we reveal that their cross-linking ability triggers specific and fast endocytosis of the receptor, independent of clathrin and dynamin. Upon aggregation, canonical clathrin-dependent cargoes are redirected into the aggregation-dependent endocytosis (ADE) pathway. ADE is an actin-driven process, which morphologically resembles macropinocytosis. Physical and chemical stress-induced aggregation of surface proteins also triggers ADE, facilitating their degradation in the lysosome. This study pinpoints aggregation of extracellular domains as a trigger for rapid uptake and lysosomal clearance which besides its proteostatic function has potential implications for the uptake of pathological protein aggregates and antibody-based therapies.

description: We investigate the implications of the long-rang self-interaction on both the self-capture and the annihilation of the self-interacting dark matter (SIDM) trapped in the Sun. Our discussion is based on a specific SIDM model in which DM particles self-interact via a light scalar mediator, or Yukawa potential, in the context of quantum mechanics. Within this framework, we calculate the self-capture rate across a broad region of parameter space. While the self-capture rate can be obtained separately in the Born regime with perturbative method, and the classical limits with the Rutherford formula, our calculation covers the gap between in a non-perturbative fashion. Besides, the phenomelogy of both the Sommerfeld-enhanced s- and p-wave annihilation of the solar SIDM is also involved in our discussion. Moreover, by combining the analysis of the Super-Kamiokande (SK) data and the observed DM relic density, we constrain the nuclear capture rate of the DM particles in the presence of the dark Yukawa potential. The consequence of the long-range dark force on probing the solar SIDM turns out to be significant if the force-carrier is much lighter than the DM particle, and a quantitative analysis is provided.

description: We consider $Λ$=0 three dimensional gravity with asymptotically flat boundary conditions. This system was studied by Ashtekar and Varadarajan within the second order formalism -with metric variables- who showed that the Regge-Teitelboim formalism yields a consistent Hamiltonian description where, surprisingly, the energy is bounded from below and from above. The energy of the spacetime is, however, determined up to an arbitrary constant. The natural choice was to fix that freedom such that Minkowski spacetime has zero energy. More recently, Marolf and Patiño started from the Einstein-Hilbert action supplemented with the Gibbons-Hawking term and showed that, in the 2+1 decomposition of the theory, the energy is shifted from the Ashtekar-Varadarajan analysis in such a way that Minkowski spacetime possesses a negative energy. In this contribution we consider the first order formalism, where the fundamental variables are a so(2,1) connection $ω_a{^I}_J$ and a triad $e_a^I$. We consider two actions. A natural extension to 3 dimensions of the consistent action in 4D Palatini gravity is shown to be finite and differentiable. For this action, the 2+1 decomposition (that we perform using two methods) yields a Hamiltonian boundary term that corresponds to energy. It assigns zero energy to Minkowski spacetime. We then put forward a totally gauge invariant action, and show that it is also well defined and differentiable. Interestingly, it turns out to be related, on shell, to the 3D Palatini action by an additive constant in such a way that its associated energy is given by the Marolf-Patiño expression. Thus, we conclude that, from the perspective of the first order formalism, Minkowski spacetime can consistently have either, zero, or a negative energy equal to -1/4G, depending on the choice of consistent action employed as starting point.
