description: Superconductivity and magnetism are usually the conflicting (competing) phenomena. We show, however, that in nanoscopic objects the electron pairing may promote the magnetic ordering. Such situation is possible at low temperatures in the quantum dots placed between the conducting and superconducting reservoirs, where the proximity induced electron pairing cooperates with the correlations enhancing the spin-exchange interactions. The emerging Kondo resonance, which is observable in the Andreev conductance, can be significantly enhanced by the coupling to superconducting lead. We explain this intriguing tendency within the Anderson impurity model using: the generalized Schrieffer-Wolff canonical transformation, the second order perturbative treatment of the Coulomb repulsion, and the nonperturbative numerical renormalization group calculations. We also provide hints for experimental observability of this phenomenon.

description: Event detection (ED), a sub-task of event extraction, involves identifying triggers and categorizing event mentions. Existing methods primarily rely upon supervised learning and require large-scale labeled event datasets which are unfortunately not readily available in many real-life applications. In this paper, we consider and reformulate the ED task with limited labeled data as a Few-Shot Learning problem. We propose a Dynamic-Memory-Based Prototypical Network (DMB-PN), which exploits Dynamic Memory Network (DMN) to not only learn better prototypes for event types, but also produce more robust sentence encodings for event mentions. Differing from vanilla prototypical networks simply computing event prototypes by averaging, which only consume event mentions once, our model is more robust and is capable of distilling contextual information from event mentions for multiple times due to the multi-hop mechanism of DMNs. The experiments show that DMB-PN not only deals with sample scarcity better than a series of baseline models but also performs more robustly when the variety of event types is relatively large and the instance quantity is extremely small.

description: Transverse thermoelectric effects in response to an out-of-plane heat current have been studied in an external magnetic field for ferromagnetic superlattices consisting of La0.67Sr0.33MnO3 and SrRuO3 layers. The superlattices were fabricated on SrTiO3 substrates by pulsed laser deposition. We found that the sign of the transverse thermoelectric voltage for the superlattices is opposite to that for La0.67Sr0.33MnO3 and SrRuO3 single layers at 200 K, implying an important role of spin Seebeck effects inside the superlattices. At 10 K, the magnetothermoelectric curves shift from the zero field due to an antiferromagnetic coupling between layers in the superlattices.

The impact of iodinated contrast media in hospital wastewater on drinking water quality in North Carolina
Creators: name: Sprouse, Lauren
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Iodinated trihalomethanes (iodo-THMs) are an unregulated class of disinfection byproduct (DBP) of increasing public health concern due to their elevated toxicity in comparison to regulated THMs, even at their lower occurrence concentrations. Iodinated contrast media (ICM), specifically iohexol because of its prevalence in North Carolina, are a major source of iodine in surface waters that receive wastewater effluent due to their biological inactivity and persistence through wastewater treatment. Many of these waters feed downstream drinking water treatment plants (DWTPs). This study investigated whether the presence of iohexol in drinking water sources can lead to the formation of iodo-THMs in disinfected drinking water impacted by upstream medical waste discharges by determining the conditions under which iohexol releases iodine to form iodo-THMs and applying equivalent conditions to natural waters and DWTP samples. Using tryptophan as a surrogate for natural organic matter (NOM) in surface waters, reactions with chlorine in the presence and absence of up to 5 mg/L iohexol formed only chloroform, while similar reactions involving monochloramine yielded no detectable THMs. Samples collected from four points in a DWTP were characterized and confirmed the presence of tryptophan-like NOM, associated with wastewater effluent, in each sample. Subsequent reactions of source water, post-powdered activated carbon (PAC), and post-ozonation samples with chlorine and monochloramine (target disinfectant residual of 3 mg/L as Cl2) in the presence and absence of 5 mg/L iohexol were evaluated to determine iodo-THM formation. Chlorination of samples showed formation of chloroform, bromodichloromethane, and dibromochloromethane, as well as two iodo-THMs, dichloroiodomethane and bromodiiodomethane, regardless of iohexol addition, while chlorodiiodomethane formed only after chlorination of source water in the presence of the iohexol. Chlorination of post-ozonation samples produced less iodo-THM formation compared to chlorination of source water and post-PAC samples. Though iodine was already present in sampled waters, chloramination yielded no quantifiable iodo-THMs even after iohexol addition, but yielded chloroform in reactions with source water, though at much lower concentrations than with equivalent disinfectant residuals after chlorination. These findings suggest that the combination of ozonation and monochloramine disinfection can decrease formation of iodo-THMs in drinking water; however, significant reduction of iodine-containing precursors in surface drinking water sources may only be possible with regulations on medical waste discharge into sewage systems, or with substitution of ICM alternatives that do not contain DBP precursors.

Foucault with Sade
Creators: name: Lopez, Matthew
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: This essay attempts to assess the writings of the Marquis de Sade in terms of the theory of power elaborated by Michel Foucault. Through a careful analysis of the 600 “passions” in Sade’s 120 Days of Sodom, it defines what he calls “libertinage” as a production of erotic knowledge that brings the body within a general grid of administration. Sade’s writing of the body’s dissolution demonstrates a “power over life” that Foucault describes in the closing section of his History of Sexuality, which does not rule through the subtractive dimension of death, but through the apprehension and creation of life at the level of its unformed substance. In this context, Sade appears as the first writer of a distinctly modern power, which his texts making visible a real transformation that Foucault described in the context of history.
Mutations in Drosophila tRNA processing enzymes cause neurological phenotypes

description: Pontocerebellar Hypoplasia (PCH) is a term used to describe a set of human neurological disorders characterized by microcephaly, developmental delays, and intellectual disability. PCH is associated with mutations in several different tRNA processing factors. Mature tRNAs are generated by multiple RNA processing events, which can include removal of intervening sequences (introns). In humans, the tRNA splicing endonuclease (TSEN) complex removes introns located in the anticodon loop of certain pre-tRNAs. This complex also contains the RNA kinase, CLP1. We wanted to determine if the neuronal phenotypes associated with mutations in human TSEN or CLP1 are conserved in other organisms. To this end, we identified the gene crowded by cid (cbc) as a CLP1 ortholog in the fruit fly Drosophila melanogaster. We characterized mutations in cbc and the fly ortholog of human TSEN54 using assays for viability, locomotion, and larval brain morphology. We observed that mutations in cbc and tsen54 resulted in reduced viability, developmental delays, impaired locomotion, and reduced brain lobe volume. These mutations also resulted in increased cell death in larval brains. Our findings indicate that we can model a human neurological disease in a genetically tractable invertebrate. We plan to use these models to test linkages between tRNA processing and disease phenotypes in order to further understand the molecular basis of neurological diseases like PCH.

Magnetic Sense of Juvenile Gulf Flounder (Paralichthys albigutta)

Year: 2019

description: 	Diverse marine taxa use Earth's magnetic field for navigation. This ability, known as magnetic navigation, has classically been grouped into two main types – the magnetic “compass” and “map” sense. Organisms possessing a magnetic compass sense are able to use the Earth’s magnetic field to gain directional information, similar to a human compass. In contrast, an organism possessing a magnetic map sense uses the Earth’s magnetic field to determine their position relative to a goal, similar to a human GPS. We assessed for the presence of both a magnetic compass and map sense in juvenile Gulf Flounder (Paralichthys albigutta), a species of migratory flatfish found in coastal waters spanning from North Carolina to the Gulf of Mexico. In both experiments, a magnetic coil system was used to produce different magnetic field treatments. To test for a magnetic compass sense, flounder were tested in one of two magnetic treatments: (1) the ambient magnetic field of the test site; (2) the same magnetic field but with reversed polarity, where the direction of magnetic north was reversed. To search for the presence of a magnetic map sense, we tested flounder in one of two magnetic fields that exist at two locations: (1) north of the test site (near New Jersey); and (2) south of the test site (near Jamaica). Flounder consistently oriented towards a magnetic direction in our compass experiments, which suggests the presence of a compass sense. In the magnetic map experiments, flounder exhibited orientations that were significantly different between northern and southern treatments, providing evidence for a magnetic map sense. Considering past magnetic navigation research has mainly focused on long-distance migrants, the discovery of a both a magnetic compass and map sense in flatfish brings to light how these senses could be useful for organisms undergoing relatively shorter migrations between nearshore and offshore environments.

description: A CNOT circuit is the key gadget for entangling qubits in quantum computing systems. However, the qubit connectivity of noisy intermediate-scale quantum (NISQ) devices is constrained by their {limited connectivity architecture}. To improve the performance of CNOT circuits on NISQ devices, we investigate the optimization of the size/depth of CNOT circuits under the limited connectivity architecture. We present a method that can optimize the size of any $n$-qubit CNOT circuit $O\left(\frac{n^2}{\log δ}\right)$ on any connected graph with minimum degree $δ$, and prove this bound is optimal for the regular graph. For the near-term sparsely connected structure, we additionally present a method that can optimize the size of any $n$-qubit CNOT circuit to below $2n^2$. The numerical experiment shows that our method performs better than state-of-the-art results. Specifically, we present an example to illustrate the applicability of our algorithm. For the grid structure, which is commonly used in current quantum devices, we demonstrate that the depth of any $n$-qubit CNOT circuit can be optimized to be linear in $n$ with certain ancillary qubits (ancillas). Experimental results indicate that this method has significant improvements compared with all of the existing methods. We additionally test our algorithms on the five-qubit IBMQ devices, and the experiments show that the measurement results of the optimized circuit with our algorithm are more robust to noise compared with the IBM mapping method.

description: We establish the notion of a ``projective analytic vector'', whose defining requirements are weaker than the usual ones of an analytic vector, and use it to prove generation theorems for one-parameter groups on locally convex spaces. More specifically, we give a characterization of the generators of strongly continuous one-parameter groups which arise as the result of a projective limit procedure, in which the existence of a dense set of projective analytic vectors plays a central role. An application to strongly continuous Lie group representations on Banach spaces is given, with a focused analysis on concrete algebras of functions and of pseudodifferential operators.

description: We introduce a new density for the representation of quantum states on phase space. It is constructed as a weighted difference of two smooth probability densities using the Husimi function and first-order Hermite spectrograms. In contrast to the Wigner function, it is accessible by sampling strategies for positive densities. In the semiclassical regime, the new density allows to approximate expectation values to second order with respect to the high frequency parameter and is thus more accurate than the uncorrected Husimi function. As an application, we combine the new phase space density with Egorov's theorem for the numerical simulation of time-evolved quantum expectations by an ensemble of classical trajectories. We present supporting numerical experiments in different settings and dimensions.

description: Harmful algal bloom (HAB) events have become increasingly frequent in coastal and estuarine regions worldwide. In addition to deterring coastal economies, HABs produce toxins that adversely affect humans and aquatic organisms, and the decomposition of these blooms results in hypoxic “dead zones” which degrade habitats. HAB formation is controlled by factors such as anthropogenic eutrophication, global temperature rise, and increasingly frequent hydrologically-extreme events which disrupt and alter estuary baseline properties such as salinity regimes. The composition and distribution of phytoplankton communities may become more difficult to predict as estuary baselines continue to shift. It is therefore necessary to understand the relationship between nutrient limitation and phytoplankton growth under varying hydrologic and salinity conditions. Bioassay experiments were conducted in two consecutive bloom years and different seasons on the Chowan River Estuary, an area impacted by eutrophication and annual summer cyanobacterial HABs. The phytoplankton were exposed to varying salinity and nutrient concentrations and analyzed for biomass accumulation, interactive effects of nutrient availability and salinity tolerance, and effects on class-level community composition. Salinities above 2 psu were found to be generally unfavorable for phytoplankton growth; however, increased nutrient availability offset this salinity sensitivity, allowing more growth to occur. Phytoplankton classes with higher salinity tolerance, particularly green algae and cyanobacteria, also exhibited a competitive advantage in nutrient uptake and thus showed more growth at higher salinities. Seasonally consistent trends were identified: under nutrient- replete conditions, salinity-controlled growth was more prominent, while under nutrient stress, nutrient limitation determined growth. Nitrogen availability was a dominant factor in stimulating algal growth across seasons; thus, reducing anthropogenic N-loading is recommended to control bloom formation.

description: Automata learning is a popular technique used to automatically construct an automaton model from queries. Much research went into devising ad hoc adaptations of algorithms for different types of automata. The CALF project seeks to unify these using category theory in order to ease correctness proofs and guide the design of new algorithms. In this paper, we extend CALF to cover learning of algebraic structures that may not have a coalgebraic presentation. Furthermore, we provide a detailed algorithmic account of an abstract version of the popular L* algorithm, which was missing from CALF. We instantiate the abstract theory to a large class of Set functors, by which we recover for the first time practical tree automata learning algorithms from an abstract framework and at the same time obtain new algorithms to learn algebras of quotiented polynomial functors.

description: Based on a combination of X-ray diffraction, electrical transports, magnetic susceptibility, specific heat and pressure effect measurements, we report a series of BiS$_{2}$-based Sr$_{1-x}$Pr$_{x}$FBiS$_{2}$ superconductors with the maximum $T_c$ of 2.7 K for $x =$ 0.5 at ambient pressure. Superconductivity can be only observed at 0.4 $\leq$ x $\leq$ 0.7 while the normal state resistivity shows the semiconducting-like behaviors. $χ(T)$ displays the low superconducting shielding volume fractions and $C(T)$ does not exhibit distinguishable anomaly around $T_c$, suggesting a filamentary superconductivity in the Pr-doped polycrystalline samples. By varying doping concentrations, an electrnoic phase diagram can thus be established. Upon applying pressure on the optimal doping Sr$_{0.5}$Pr$_{0.5}$FBiS$_{2}$ system, $T_c$ is abruptly enhanced, reaches 8.5 K at a critical pressure of $P_c =$ 1.5 GPa and remains a slight increase up to 9.7 K up to 2.5 GPa. Accompanied with the enhancement of superconductivity from the low-$T_c$ phase to the high-$T_c$ phase, the normal state undergoes a semiconductor-to-metal transition under pressure. The scenario can be linked to the enhancement of orbital overlap of Bi-6p and S-p, contributing to the bulk superconductivity above $P_c$. Phase diagram for Sr$_{0.5}$Pr$_{0.5}$FBiS$_{2}$ is also obtained.

description: The basic stationary buoyant flow in a vertical annular porous passage induced by a boundary temperature difference is investigated. The vertical cylindrical boundaries are considered both isothermal and permeable to external fluid reservoirs. There exists a stationary parallel velocity field with a zero flow rate and pure conduction heat transfer. Its linear stability is analysed with normal mode perturbations of the pressure and temperature fields. The transition to convective instability is caused by the basic horizontal temperature gradient. Hence, its nature differs from that of the usual Rayleigh-Bénard instability. The linear dynamics of the perturbed flow is formulated as an eigenvalue problem, solved numerically. Its solution provides the neutral stability curve at each fixed aspect ratio between the external radius and the internal radius. The critical Rayleigh number triggering the instability is evaluated for different aspect ratios. It is shown that the system becomes more an more unstable as the aspect ratio increases, with the critical Rayleigh number dropping to zero when the aspect ratio tends to infinity.

description: Intervention for students with Autism Spectrum Disorder (ASD) in public schools is a key to unlocking the potential of young students. Evidence-based practice is used in a variety of differing ways to provide the best intervention. The purpose of this paper is to conduct a literature review on the current literature of communication interventions for early education students with autism spectrum disorder and determine what makes these treatments effective. Six intervention methods were chosen to be focused on in this literature review: (a) TEACCH, (b) Visual Schedules, (c) ABA, (d) Augmentative and Alternative Communication, (e) Verbal Behavior Therapy, and (f) Social Skills. A literature review of 19 studies was conducted to answer the research questions in the current review. All 19 of the studies included the analysis of one of the listed intervention methods. The literature review revealed that there are two key factors in ensuring success in ASD intervention in public schools: consistency and opportunity. Providing consistency across the environments of the student and opportunity for appropriate intervention sets up a prospect for success. While there were a number of limitations in the current literature review, the gathered data should still be interpreted. Moving into future research, more research needs to take place directly in the public school setting as this is such an important place for school-age children with ASD.

description: Развитие государства неразрывно связано с разработкой и совершенствованием форм и способов использования бюджетных и иных финансовых средств, направляемых на удовлетворение потребностей общества. Теоретизация и юридизация подходов к выполнению функций государства привела к созданию бюджетного механизма, ставшего ядром государственного управления. Поэтому вопрос качества государственного управления в настоящее время рассматривается в контексте эффективности бюджета, прежде всего в его расходной части. Данный вопрос не теряет актуальности с течением времени, несмотря на активное стремление государства применять новые управленческие решения, такие как результативное, программное, проектное бюджетирование, мониторинг качества финансового менеджмента и другие. Все эти усилия пока не обеспечили достижение желаемого уровня распоряжения финансами, что нередко вызывает обоснованную критику. Одновременно цели и методы управления постоянно меняются в зависимости от условий жизнедеятельности общества, функционирования финансов, правотворчества и правореализации. В связи с этим на первый план выходят задачи поиска правовых средств, которые позволят обеспечить качество государственного управления при осуществлении бюджетных расходов и юридизации нововведений в управленческой деятельности.

description: Fiscal decentralization is seen as part of a reform agenda in developing countries to strengthen regional and local governments. It is believed that it improves the efficiency of public service delivery through preference matching and allocation efficiency. In light of this, this study was conducted to assess the practices of Woreda level fiscal decentralization in Addis Ababa City Government. In doing this study, explanatory mixed method research design was followed. Subjects of the study were government officials working in selected Woredas and sub-cities of Addis Ababa city. In the study, multi-stage sampling technique was used to select representative respondents. To this effect, one hundred ninety-two participants were selected using multi-stage sampling technique. Besides, sub-city and Woreda Finance and Economic Development Bureaus officials were purposely selected to conduct key informant interviews. The data gathering instruments were questionnaire, key informant interviews, and document analysis. The study followed statistical tests to test the research hypotheses. It applied Kruskal Wallis test of significance. The study involved strict respect for informed consent, voluntary participation, and confidentiality. The findings of the statistics tests indicates that respondents’ responses concerning autonomy of Woredas in planning and budgeting, revenue generation and retention, expenditure assignments were significantly different. This implies that there is absence of uniformity in the practices of these aspects of fiscal decentralization in the city. On the contrary, the respondents’ response concerning the functionalities of institutional and legal frameworks, inter-governmental fiscal relations, challenges, and constraints of fiscal decentralization, were not significantly different. In general, the practice of fiscal decentralization in the city was limited as existing institutional and legal frameworks were in short of clarity and uniformity. Respondents stated that Woreda administrations had weak revenue base, and need clear planning and budgeting, and expenditure assignment autonomy. Based on the findings of the study, the research hence recommended that existing institutional and legal frameworks should be structured in the way that it enables Woreda administrations to generate and utilize sufficient revenues, plan and budget their own activities, have clear autonomy of expenditure assignments. Inter-governmental fiscal relations should also be planned to reduce the vertical imbalances observed at Woreda Administration level.

description: A Weyl semimetallic state with pairs of nondegenerate Dirac cones in three dimensions was recently predicted to occur in the antiferromagnetic state of the pyrochlore iridates. Here, we show that the THz optical conductivity and temperature dependence of free carriers in the pyrochlore Eu2Ir2O7 match the predictions for a Weyl semimetal and suggest novel Dirac liquid behavior. The interband optical conductivity vanishes continuously at low frequencies signifying a semimetal. The metal-insulator transition at T_N = 110 K is manifested in the Drude spectral weight, which is independent of temperature in the metallic phase, and which decreases smoothly in the ordered phase. The temperature dependence of the free carrier weight below T_N is in good agreement with theoretical predictions for a Dirac material. The data yield a Fermi velocity v_F=4x10^7 cm/s, a logarithmic renormalization scale Lambda_L=600 K, and require a Fermi temperature of T_F=100 K associated with residual unintentional doping to account for the low temperature optical response and dc resistivity.

description: Multicultural competence enables counselors to effectively serve clients from diverse backgrounds (Ratts & Greenleaf, 2018). It is particularly important for school counselors to be culturally aware because their work and interactions with students have long term effects (Priest, 
Trenerry, Truong, Karlsen, & Kelly, 2013). As racial demographics in the United States continues to shift toward increased racial diversity, it is particularly important for school counseling students to develop multicultural competence so they can be effective at meeting the 
needs of their culturally diverse student populations once entering the field (Blue, Mupinga, Clark, DeLuca, & Kelly, 2018). Therefore, the purpose of this study is two-fold: First, this study explores whether one multicultural training course has some bearing on school counseling 
students’ perceived multicultural competency. Second, this study examines the factor structure of the Multicultural Counseling Competence and Training Survey-Revised (MCCTS-R), which was normed on professional school counselors. Exploratory factor analyses reveal one dimension of multicultural counseling competency for school counseling students, as opposed to the three dimensions found on professional school counselors. Implications for school counselor training and research are discussed. 
Key words: multicultural competence, MCCTS-R, school counseling, counselor training

description: Knowledge transfer is shown to be a very successful technique for training neural classifiers: together with the ground truth data, it uses the "privileged information" (PI) obtained by a "teacher" network to train a "student" network. It has been observed that classifiers learn much faster and more reliably via knowledge transfer. However, there has been little or no theoretical analysis of this phenomenon. To bridge this gap, we propose to approach the problem of knowledge transfer by regularizing the fit between the teacher and the student with PI provided by the teacher. Using tools from dynamical systems theory, we show that when the student is an extremely wide two layer network, we can analyze it in the kernel regime and show that it is able to interpolate between PI and the given data. This characterization sheds new light on the relation between the training error and capacity of the student relative to the teacher. Another contribution of the paper is a quantitative statement on the convergence of student network. We prove that the teacher reduces the number of required iterations for a student to learn, and consequently improves the generalization power of the student. We give corresponding experimental analysis that validates the theoretical results and yield additional insights.

description: The recent discovery by Bachetti et al. (2014) of a pulsar in M82 that can reach luminosities of up to 10^40 ergs s^-1, a factor of ~100 the Eddington luminosity for a 1.4 Msol compact object, poses a challenge for accretion physics. In order to better understand the nature of this source and its duty cycle, and in the light of several physical models that have been subsequently published, we conduct a spectral and temporal analysis of the 0.5-8 keV X-ray emission from this source from 15 years of Chandra observations. We fit the Chandra spectra of the pulsar with a power-law model and a disk black body model, subjected to interstellar absorption in M82. We carefully assess for the effect of pile-up in our observations, where 4/19 observations have a pile-up fraction >10%, which we account for during spectral modeling with a convolution model. When fitted with a power-law model, the average photon index when the source is at high luminosity (L_X>10^39 ergs s^-1) is Gamma=1.33+/-0.15. For the disk black body model, the average temperature is T=3.24+/-0.65 keV, consistent with other luminous X-ray pulsars. We also investigated the inclusion of a soft excess component and spectral break, finding that the spectra are also consistent with these features common to luminous X-ray pulsars. In addition, we present spectral analysis from NuSTAR over the 3-50 keV range where we have isolated the pulsed component. We find that the pulsed emission in this band is best fit by a power-law with a high-energy cut-off, where Gamma=0.6+/-0.3 and E_C=14^{+5}_{-3} keV. While the pulsar has previously been identified as a transient, we find from our longer-baseline study that it has been remarkably active over the 15-year period, where for 9/19 (47%) observations that we analyzed, the pulsar appears to be emitting at a luminosity in excess of 10^39 ergs s^-1, greater than 10 times its Eddington limit.

description: Dietitians are uniquely positioned within the healthcare system to tackle many of the chronic diseases on the rise in the US. Obesity and diabetes continue to have high prevalence in US adults. However, these chronic diseases disproportionately affect communities of color. The disparity in health outcomes results from an intricate web of reasons, including social determinants of health and a lack of diversity in the healthcare workforce. Having a more diverse healthcare workforce can lead to a healthier population. Research has shown that increasing diversity in the healthcare workforce has the dual benefit of increasing access to care and bettering health outcomes to those who are most affected by chronic health conditions. Unfortunately, dietetics is overwhelmingly white and does not reflect the rapidly changing American demographics. One way of increasing the diversity among dietitians is to increase the diversity in dietitian education programs. This paper will look specifically at the impact of graduate admission practices on diversity across disciplines and in the UNC Chapel Hill MPH-RD program. In addition, this paper will seek to make a case for a more holistic review of applications as one method to increase the diversity in UNC Chapel Hill’s dietitian training program. Analysis of UNC-MPH RD applicant data from 2016-2019 indicates that the use of a GRE cut off in admissions adversely affect applicants from underrepresented minority groups.
