description: The ability to live in coherent superpositions is a signature trait of quantum systems and constitutes an irreplaceable resource for quantum-enhanced technologies. However, decoherence effects usually destroy quantum superpositions. It has been recently predicted that, in a composite quantum system exposed to dephasing noise, quantum coherence in a transversal reference basis can stay protected for indefinite time. This can occur for a class of quantum states independently of the measure used to quantify coherence, and requires no control on the system during the dynamics. Here, such an invariant coherence phenomenon is observed experimentally in two different setups based on nuclear magnetic resonance at room temperature, realising an effective quantum simulator of two- and four-qubit spin systems. Our study further reveals a novel interplay between coherence and various forms of correlations, and highlights the natural resilience of quantum effects in complex systems.

description: We consider the sine-Gordon equation on metric graphs with simple topologies and derive vertex boundary conditions from the fundamental conservation laws, such as energy and current conservation. Traveling wave solutions for star and tree graphs are obtained analytically in the form of kink, antikink and breather solitons for a special case. It is shown that these solutions provide reflectionless soliton transmission at the graph vertex. We find the sum rule for bond-dependent coefficients making the sine-Gordon equation embedded on the graph completely integrable. For the general case the problem is solved numerically and the vertex scattering is quantified. Applications of the obtained results to Josephson junction networks, DNA double helix and elastic fibre networks are discussed.

Health and household access to water and sanitation: a global analysis and systematic literature review
Creators: name: Overbo, Alycia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Millennium Development Goal target 7c sought to improve global access to safe water and sanitation, but different benchmarks were used to monitor "improved" access; the water benchmark is community-level access, and for sanitation it is household-level. Household-level sanitation is considered safer than shared sanitation, yet the relative health impacts of access to shared water sources and water supplies on premises have not been established. An analysis evaluated global progress towards water and sanitation targets under alternative benchmarks, and a systematic literature review was conducted to compare the relative health impacts of using shared water sources and at-house water supplies. Results indicate that water and sanitation have similar coverage deficits for household-level access and that individuals with at-house water supplies may experience lower odds of water-washed diseases and improved height outcomes. Promoting at-house water supplies through policy and development goals may realize potential health gains, particularly in underserved rural areas.

description: The Wide Field Camera 3 (WFC3) on Hubble Space Telescope (HST) is currently one of the most widely used instruments for observing exoplanetary atmospheres, especially with the use of the spatial scanning technique. An increasing number of exoplanets have been studied using this technique as it enables the observation of bright targets without saturating the sensitive detectors. In this work we present a new pipeline for analyzing the data obtained with the spatial scanning technique, starting from the raw data provided by the instrument. In addition to commonly used correction techniques, we take into account the geometric distortions of the instrument, whose impact may become important when combined to the scanning process. Our approach can improve the photometric precision for existing data and also push further the limits of the spatial scanning technique, as it allows the analysis of even longer spatial scans. As an application of our method and pipeline, we present the results from a reanalysis of the spatially scanned transit spectrum of HD 209458 b. We calculate the transit depth per wavelength channel with an average relative uncertainty of 40 ppm. We interpret the final spectrum with T-Rex, our fully Bayesian spectral retrieval code, which confirms the presence of water vapor and clouds in the atmosphere of HD 209458 b. The narrow wavelength range limits our ability to disentangle the degeneracies between the fitted atmospheric parameters. Additional data over a broader spectral range are needed to address this issue.

Aldehydes Formed during Ozone Treatment of Real and Model Drinking Waters
Creators: name: Schechter, Daniel S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: Ozone is gaining in popularity as an oxidant and disinfectant for drinking water supplies in the United States. It is already widely used in Europe, where it is also frequently used to destroy micropollutants in water. This rise in popularity can be associated with concerns over the health effects of chlorination by-products. These concerns have been codified into the Disinfectants and Disinfection By-products (D/DBP) Rule which regulate two classes of chlorination by-products, trihalomethanes (THMs) and haloacetic acids (HAAs). While these regulations will encourage utilities to examine alternativedisinfectants such as ozone, there is a significant gap in our knowledge of the ozonation by-products. Without research on ozonation by-products, many feel that we may simply trade a "known" risk (chlorination DBFs) for an "unknown" risk (ozonation DBFs). This study was designed to explore the formation of aldehydes, a primary class of by-products formed when treating drinking waters with ozone. This study examines the formation of aldehydes in four ozonated waters under different conditions. To perform most of the experiments, model waters were used in which organic extracts from four drinking water sources were reconstituted at uniform water quality conditions. It is intended that the data and conclusions in this report will help to provide information on the ozonation conditions that create aldehydes. Additional work was also conducted to address the role of ozone in creating biodegradable organic matter (BOM) in drinking waters. This study is part of a larger project sponsored by the American Water Works Association Research Foundation (AWWARF). Future related work will investigate aldehydes as precursors to halogenated by-products upon subsequent chlorination or chloramination. Additionally, characterization of the organic material in the source waters used will help to explain why different types of natural organic material react to form different levels of disinfection by-products. This study attempts to furnish information to further shrink the knowledge gap on ozonation by-products. This should lead to a better understanding of the implications that new treatment technologies and regulations have for the quality of our drinking water.

description: We study the loop corrections to the scalar propagator and the fermionic self-energy for the mass dimension one fermionic dark matter with the Yukawa interaction. We find, in the former case, there is a non-vanishing Lorentz-violating term while the later is Lorentz-invariant. Our study of the fermionic loop correction shows that unitarity demands the fermionic mass must be at least half of the bosonic mass and that the Lorentz-violating term makes a non-trivial correction to the bosonic propagator. We discuss what these results mean in the context of the Standard Model and the possibility of bypassing the unitarity constraint. In the simplest scenario, within the framework of standard quantum field theory, by identifying the scalar boson to be the Higgs boson with a mass of 125 GeV, the mass of the fermion must be at least 62.5 GeV.

description: Blue-Cloud aims to become the reference point for the "Blue community" in the need of data, analytics tools and computing resources in EOSC and in the future Blue Economy & marine research landscape. Blue-Cloud aims to pilot a cyber platform bringing together and providing access to: 1) multidisciplinary data from observations and models, 2) analytical tools, & 3) computing facilities essential to support research to better understand and manage the many aspects of ocean sustainability. These objectives will be pursued throughout the project's 36-month implementation by a consortium composed by twenty beneficiaries. The formulation, implementation and adoption by project partners of common project procedures, conventions, and well defined processes are therefore essential for the project management approach, to ensure the results are produced conform to defined standards and, ultimately, to ensure that the series of established Key Performance Indicators (KPIs) are met. The Blue-Cloud Project, Quality and Risk Management Plan is the "Project Handbook" that defines the organisation and the methodology that all partners and nodes shall apply throughout the project when delivering project results, documents and internal work progress reports. It forms a common standard to guarantee quality for the entire project lifecycle. First and foremost, this document provides: Management structure and procedures; Quality assurance framework including collaboration tools, quality control of the project, of its deliverables and milestones, organisation of regular meetings, reporting procedures, preparation of review meetings, procedures for dissemination, communication and publications and KPIs; IPR & Innovation Management; Risk management and contingency plan monitoring. Its implementation will ensure regular appraisal of KPIs defined to measure progress and gauge impact; and will provide the needed methodology to ensure a smooth communication process among the different actors, and the diversity of tasks foreseen. The main goal is to meet the expectations and commitment made by the European Commission as a funding body of the project as well as expectations and needs of different stakeholders collaborating with Blue-Cloud.

Analysis of Respirator Cartridges and Filters as a Determination of Occupation Exposure
Creators: name: Ramstack, Brian E.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1990

description: This research attempted to determine occupational exposure from the amount of contaminant deposited on respirator cartridges. The flowrate through the respirator was estimated by existing ergonomic and respiratory ventilation models. The respirator concentrations were compared with simultaneous breathing zone air samples. A respiration flow model was modified into 18 different variations depending on 1) the increase in oxygen required per increase in workload; 2) estimate of total ergonomic workload; and 3) the basal oxygen exceeded the calculated maximum possible flowrate. Of the 18 models only 5 were acceptable. Dust/mist respirator results were 1.5 to 2.2 times less than the breathing zone samples. Respirator cartridge organic vapor constituents were 1.0 to 2.5 times less than the charcoal tube values. The models appear to overestimate the actual flow, although factors such as mask leakage, faceshield blocking, sensitivity of filter pads to relative humidity, and differences in analytical sensitivities made quantitative conclusions unreliable. The results of organic vapor respirator cartridges did show countenance for this procedure in screening workplace exposures or estimating a respirator workplace protection factor.

Developing Regulations to Limit Emissions of Hazardous Air Pollutants under the Clean Air Act Amendments
Creators: name: Rimer, Kelly Anne
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: In 1970, Congress passed Amendments to the Clean Air Act which included a provision requiring the EPA to reduce emissions of hazardous air pollutants (HAPs). The Amendments required the agency to promulgate emission standards that would provide an ample margin of safety to protect public health. The EPA was largely unsuccessful in promulgating rules under this framework. In 1990, Congress passed new Amendments to the Clean Air Act. These Amendments significantly changed the way the EPA was to develop emission standards for HAPs. The new Amendments require the agency to first set standards based on existing methods to emissions reduction, then evaluate remaining public health risks, within eight years, and set risk-based standards if necessary. The 1990 Amendments attempted to remove major impediments to standard setting under the former program: listing chemicals as HAPs was largely eliminated; setting health-based standards was postponed and may not be necessary in all cases; and deadlines were extended. The EPA has made some internal progress as a result of these changes but it still far behind its mandated regulatory schedule. How the agency succeeds as implementation proceeds will depend on how it manages the intractable regulatory process, and how it prepares for the second, risk-based phase of the program.

The range in which the studied cluster is paramagnetic is considered. The results are obtained by means of exact numerical diagonalization. Such thermodynamic quantities as entropy, specific heat, magnetic susceptibility, spin-spin correlations and double occupancy are discussed. Particular emphasis is put on the behaviour of local maxima of specific heat and susceptibility, which are analysed in terms of Schottky anomalies.
Survey of Tritium in Soil in An Assessment of A University Low-level Radioactive Waste Facility
Creators: name: Maples, Charles E.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1990

description: Soil samples from two low-level radioactive waste facilities belonging to the University of North Carolina at Chapel Hill were evaluated for their tritium content. The interstitial soil water and associated tritium activity was separated from the soil by distillation at high temperatures. Condensed water from the soil samples was then counted in a liquid scintillation counter. At the Horace Williams Airport site, no detectable tritium activity was found. At the Mason Farm site, no tritium activity was found off site but trace amounts (less than 30 pCi/g of soil) were found in soil between individual burial pits inside the site boundaries. Soil sampled from the pits at the Mason Farm site had tritium values that ranged from non-detectable to 735 pCi/g of soil.

Ecological Risk Assessment in Hazardous Waste Management: Development of Ecological Screening Criteria for the Protection of Wildlife
Creators: name: Beaulieu, Stephen M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1995

description: The U.S. Environmental Protection Agency has developed a framework for ecological risk assessment and proposed ecological assessment methods for certain chemicals (e.g., 2,3,7,8-TCDD) and applications(e.g., Great Lakes Wildlife Criteria). However, criteria for screening ecological risks in regulatory decision-making have not been proposed for RCRA or CERCLA. This analysis presents a methodology for developing ecological screening criteria for wildlife (i.e., medium-specific exposure concentrations designed to be protective of wildlife). Multiple levels of biological organization are considered by selecting physiological endpoints that may be used to infer impacts to populations, communities, and ecosystems. A suite of ecological receptors is identified in two generic ecosystems (freshwater and terrestrial) likely to receive significant exposures to chemical stressors based on dietary habits and/or ecological niche. For nine pilot chemicals, ecotoxicological benchmarks are established for ecological receptors, including representative species of birds, mammals, soil fauna, fish, benthos, and plants, based on a review of toxicological data on wildlife and laboratory species.
Master equation for high-precision spectroscopy

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The progress in high-precision spectroscopy requires one to verify the accuracy of theoretical models such as the master equation describing spontaneous emission of atoms. For this purpose, we apply the coarse-graining method to derive a master equation of an atom interacting with the modes of the electromagnetic field. This master equation naturally includes terms due to quantum interference in the decay channels and fulfills the requirements of the Lindblad theorem without the need of phenomenological assumptions. We then consider the spectroscopy of the 2S-4P line of atomic Hydrogen and show that these interference terms, typically neglected, significantly contribute to the photon count signal. These results can be important in understanding spectroscopic measurements performed in recent experiments for testing the validity of quantum electrodynamics.

description: Let ${\mathcal D}_{n,d}$ be the set of all $d$-regular directed graphs on $n$ vertices. Let $G$ be a graph chosen uniformly at random from ${\mathcal D}_{n,d}$ and $M$ be its adjacency matrix. We show that $M$ is invertible with probability at least $1-C\ln^{3} d/\sqrt{d}$ for $C\leq d\leq cn/\ln^2 n$, where $c, C$ are positive absolute constants. To this end, we establish a few properties of $d$-regular directed graphs. One of them, a Littlewood-Offord type anti-concentration property, is of independent interest. Let $J$ be a subset of vertices of $G$ with $|J|\approx n/d$. Let $δ_i$ be the indicator of the event that the vertex $i$ is connected to $J$ and define $δ= (δ_1, δ_2, ..., δ_n)\in \{0, 1\}^n$. Then for every $v\in\{0,1\}^n$ the probability that $δ=v$ is exponentially small. This property holds even if a part of the graph is "frozen".

description: In electrical impedance tomography, algorithms based on minimizing a linearized residual functional have been widely used due to their flexibility and good performance in practice. However, no rigorous convergence results have been available in the literature yet, and reconstructions tend to contain ringing artifacts. In this work, we shall minimize the linearized residual functional under a linear constraint defined by a monotonicity test, which plays a role of a special regularizer. Global convergence is then established to guarantee that this method is stable under the effects of noise. Moreover, numerical results show that this method yields good shape reconstructions under high levels of noise without appearance of artifacts.

description: Ternary (Bi1-xSbx)2Te3 films with an Sb content between 0 and 100% were deposited on a Si(111) substrate by means of molecular beam epitaxy. X-ray diffraction measurements confirm single crystal growth in all cases. The Sb content is determined by X-ray photoelectron spectroscopy. Consistent values of the Sb content are obtained from Raman spectroscopy. Scanning Raman spectroscopy reveals that the (Bi1-xSbx)2Te3 layers with an intermediate Sb content show spatial composition inhomogeneities. The observed spectra broadening in angular-resolved photoemission spectroscopy (ARPES) is also attributed to this phenomena. Upon increasing the Sb content from x=0 to 1 the ARPES measurements show a shift of the Fermi level from the conduction band to the valence band. This shift is also confirmed by corresponding magnetotransport measurements where the conductance changes from n- to p-type. In this transition region, an increase of the resistivity is found, indicating a location of the Fermi level within the band gap region. More detailed measurements in the transition region reveals that the transport takes place in two independent channels. By means of a gate electrode the transport can be changed from n- to p-type, thus allowing a tuning of the Fermi level within the topologically protected surface states.

A conditionally exactly solvable generalization of the inverse square root potential
Creators: name: Ishkhanyan, A. M.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We present a conditionally exactly solvable singular potential for the one-dimensional Schrödinger equation which involves the exactly solvable inverse square root potential. Each of the two fundamental solutions that compose the general solution of the problem is given by a linear combination with non-constant coefficients of two confluent hypergeometric functions. Discussing the bound-state wave functions vanishing both at infinity and in the origin, we derive the exact equation for the energy spectrum which is written using two Hermite functions of non-integer order. In specific auxiliary variables this equation becomes a mathematical equation that does not refer to a specific physical context discussed. In the two-dimensional space of these auxiliary variables the roots of this equation draw a countable infinite set of open curves with hyperbolic asymptotes. We present an analytic description of these curves by a transcendental algebraic equation for the involved variables. The intersections of the curves thus constructed with a certain cubic curve provide a highly accurate description of the energy spectrum.
Water Project Benefits for Women in Rural Tanzania: Reality or Rhetoric?
Creators: name: Neitzel, Katherine S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: Though women bear the primary burden of water collection in Tanzania, both measuring the benefits of an improved water system and determining whether the women responsible for collection will realize the benefits remain unclear. This analysis pursues greater understanding of water project benefits in rural Tanzania through a literature study and econometric analyses of an existing data set. The literature suggests that power struggles may exist between men and women that may ultimately influence the allocation of benefits from an improved water system. The econometric analysis does not conclusively confirm this, but neither does it contradict it. The analysis revealed that most men and women expressed equal willingness to pay for an improved water system. It also showed that literate women were willing to pay significantly more for an improved water system than either literate men or illiterate men or women. In addition, the analysis revealed that women who believed that male luxury expenses could be reduced were willing to pay more for an improved water system than the men who were also willing to reduce luxury expenses.

description: For surface gravity waves propagating in shallow water, we propose a variant of the fully nonlinear Serre-Green-Naghdi equations involving a free parameter that can be chosen to improve the dispersion properties. The novelty here consists in the fact that the new model conserves the energy, contrary to other modified Serre's equations found in the literature. Numerical comparisons with the Euler equations show that the new model is substantially more accurate than the classical Serre equations, specially for long time simulations and for large amplitudes.
