description: Recently, Lechner, Hauke and Zoller [Science Advances, 1(9)e1500838, (2015)] have proposed a quantum annealing architecture, in which a classical spin glass with all-to-all connectivity is simulated by a spin glass with geometrically local interactions. We interpret this architecture as a classical error-correcting code, which is highly robust against weakly correlated bit-flip noise, and we analyze the code's performance using a belief-propagation decoding algorithm. Our observations may also apply to more general encoding schemes and noise models.

Microbial Communities and the Bioremediation of Polycyclic Aromatic Nitrogen Heterocycle-Contaminated Soil
Creators: name: Jewell, Emily
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Azaarenes are nitrogen heterocyclic compounds comparable to the more commonly known polycyclic aromatic hydrocarbons. These nitrogen heterocycles tend to co-exist with polycyclic aromatic hydrocarbons in contaminated soils. Despite their known toxicity and relatively high bioavailability, little research exists on the bioremediation of these chemicals in soil. This study used high-performance liquid chromatography to detect a decline in azaarene concentration in microcosms of soil samples from a former wood treatment facility in Andalucía, Spain, to which a specific azaarene was spiked. Seven azaarenes were studied: quinoline, isoquinoline, phenanthridine, acridine, benzohquinoline, benzoaacridine, and benzocacridine. Differences in the microbial communities among the microcosms were first analyzed by denaturing gradient gel electrophoresis (DGGE) of 16S rRNA genes. High-throughput sequencing of community 16S rRNA genes was then conducted to determine the organisms that responded to the addition of a given azaarene. The results suggest that the microbial communities among triplicate incubations were similar to one another, and that both the molecular weight and the position of the nitrogen in the ring structure of the azaarene can influence the microbial community responsible for degradation.
Backreaction of particle production on false vacuum decay

description: As originally described by Rubakov, particles are produced during the tunneling of a metastable quantum field. We propose to extend his formalism to compute the backreaction of these particles on the semiclassical decay probability of the field. The idea is to integrate out the external bath of particles by computing the reduced density matrix of the system. Following this approach, we derive an explicit correction factor in the specific case of scalar particle production in flat spacetime. In this given framework, we conclude that the backreaction is ultraviolet finite and enhances the decay rate. Moreover, in the weak production limit, the backreaction factor is directly given by one half of the total number of created particles. In order to estimate the importance of this correction, we apply our formalism to a toy model potential which allows us to consider both the decay of a homogeneous bounce and the nucleation of a thin-wall bubble. In the former case, the impact of the created particles is parameter dependent and we exhibit a reasonable choice of variables for which ones the backreaction is significant. In the latter case, we conclude that the backreaction is always negligible.

Optimization of EPA Method 1601 for Rapid Detection of Male-specific (F+) Coliphages in Seawater
Creators: name: Knee, Jacqueline S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Male-specific or F+ coliphages are candidate microbial indicators of fecal contamination and enteric viruses in water. As indicators, their utility depends on the ability to efficiently and reproducibly detect them in various water matrices. EPA Method 1601 is an overnight two step-enrichment spot-plate procedure used to detect low concentrations of coliphages in water. To date, the method has only been validated for use in groundwater. The objective of this study was to optimize EPA Method 1601 as rapid detection method for coliphages in seawater. This study examined potential modifications to the initial sample enrichment and to the spot-plate protocol for the variables of sample salinity (0 ppt, 8 ppt, 16 ppt, 32 ppt), nutrient medium (tryptic soy broth, TSB vs. Luria broth, LB) and incubation time (3, 5, 7, 24 hrs) on the growth of F+ coliphage prototype strains (GA, QB, SP, FD) representing different families and sub-groups. In general, coliphage concentrations increased with longer incubation time and decreasing sample salinity. The effect of media was less consistent, depending on both coliphage strain and sample salinity. After 24 hours of enrichment all four coliphages trains reached their highest observable concentrations and were readily detectable in enrichments of every salinity and media combination. This observation indicates that EPA Method 1601 is a valid method for the overnight detection of F+ coliphages in seawater. After incubation times of five hours and seven hours, the variations in salinity and media were observed to differentially affect the growth and detection of the four representative coliphage strains. Therefore, the growth of each coliphage was assessed across all salinity and media combinations for five and seven hours of incubation to determine which combinations of time, salinity, and media produced their maximum concentrations. Proposed optimum conditions for rapid enrichment of F+ coliphages by EPA Method 1601 were found to be: (1) sea water sample dilution to a final salinity of 8 or 16 ppt, (2) use of LB instead of TSB enrichment medium, and (3) enrichment incubation a minimum of seven hours. The slow growth kinetics of coliphage SP was the limiting one for optimization of conditions. Additionally, strain GA of F+ RNA coliphage group II and unidentified F+ coliphage strains in seawater samples were found to require added Mg^2+ ions in culture media for effective detection.

Distance Traveled by Municipal Solid Waste: An Analysis of Demographic and Socioeconomic Effects
Creators: name: Rosenbaum, Daniel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: North Carolina counties increasingly ship municipal solid waste (MSW) long distances for disposal, which disproportionately burdens a small number of communities with the risks associated with living near municipal solid waste landfills. Communities that are able to ship their MSW further may benefit due to decreased exposure to the negative health and economic impacts of living near landfills. Nonetheless, potential inequities stemming from shipping distances of MSW have not been previously analyzed. A mixed-effects regression model was used to test whether the distance that North Carolina counties shipped MSW for disposal was explained by the racial composition, population density, and wealth level of the counties where MSW originated in fiscal year 2012-2013. The results show that higher county wealth levels, as assessed by median house value, were associated with significantly greater shipping distances for MSW disposal (type III F(1,378)=5.9, p=0.015). The counties with highest home values shipped their waste 3 miles further away, on average, than those with the lowest house values. The effects of racial composition were significant but complex: racial composition interacted with both population density and mass of waste shipped in affecting MSW disposal distances. In low- population-density counties, a higher minority population fraction was associated with large volumes of MSW being disposed of closer to the county of origin (shipping shorter distances), whereas the opposite was true in high-population-density counties. By focusing on MSW origin, these results add to the ongoing discussion about environmental injustices and MSW disposal.

description: Sound waves from the primordial fluctuations of the Universe imprinted in the large-scale structure, called baryon acoustic oscillations (BAOs), can be used as standard rulers to measure the scale of the Universe. These oscillations have already been detected in the distribution of galaxies. Here we propose to measure BAOs from the troughs (minima) of the density field. Based on two sets of accurate mock halo catalogues with and without BAOs in the seed initial conditions, we demonstrate that the BAO signal cannot be obtained from the clustering of classical disjoint voids, but is clearly detected from overlapping voids. The latter represent an estimate of all troughs of the density field. We compute them from the empty circumsphere centers constrained by tetrahedra of galaxies using Delaunay triangulation. Our theoretical models based on an unprecedented large set of detailed simulated void catalogues are remarkably well confirmed by observational data. We use the largest recently publicly available sample of luminous red galaxies from SDSS-III BOSS DR11 to unveil for the first time a >3$σ$ BAO detection from voids in observations. Since voids are nearly isotropically expanding regions, their centers represent the most quiet places in the Universe, keeping in mind the cosmos origin and providing a new promising window in the analysis of the cosmological large-scale structure from galaxy surveys.

The Use of Thermal Inactivation of Male-Specific Coliphages as Potential Indicators of Pathogen Reductions in Thermophilic Anaerobic Digestion
Creators: name: Nappier, Sharon P.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004

description: Male-specific (F+) coliphages were investigated as indicators of virus inactivation during thermophilic digestion and other thermal processes. Because pathogen monitoring in sludge is difficult, costly, and impractical, microbial indicators are needed to predict pathogen reductions in Class A biosolids. F+ coliphages are a promising candidate indicator of fecal contamination and a surrogate for virus reduction in waste treatment processes. F+ RNA group I, F+ RNA group III, and F+ DNA phages were isolated from municipal sludge. In laboratory studies the kinetics and extent of inactivation of groups I and III F+ RNA, and F+ DNA coliphages were quantified and compared at 53°C, a temperature used in thermophilic anaerobic digestion. Isolates of groups I and III F+ RNA and F+ DNA coliphages were exposed to 53°C in an automated, thermoregulated heat block and titered after 0, 5 and 60 minutes. After 60 minutes at 53°C, F+ RNA group III coliphages were inactivated significantly greater (P < .0001) than the F+ RNA group I and F+ DNA coliphages. The inactivation kinetics of group III F+ RNA coliphages resemble those of some enteric viruses and some other pathogens. The results of this study elucidate the thermal properties of the male-specific coliphage subgroups and facilitate the development of time and temperature relationships that predict enteric virus and other pathogen reductions in thermal and thermophilic processes used to meet Class A biosolids requirements.

description: In a quantum Hall ferromagnet, the spin polarization of the two-dimensional electron system can be dynamically transferred to nuclear spins in its vicinity through the hyperfine interaction. The resulting nuclear field typically acts back locally, modifying the local electronic Zeeman energy. Here we report a non-local effect arising from the interplay between nuclear polarization and the spatial structure of electronic domains in a $ν=2/3$ fractional quantum Hall state. In our experiments, we use a quantum point contact to locally control and probe the domain structure of different spin configurations emerging at the spin phase transition. Feedback between nuclear and electronic degrees of freedom gives rise to memristive behavior, where electronic transport through the quantum point contact depends on the history of current flow. We propose a model for this effect which suggests a novel route to studying edge states in fractional quantum Hall systems and may account for so-far unexplained oscillatory electronic-transport features observed in previous studies.

description: The modelling of neutrino nucleus interactions is one of the limiting systematic errors in long base line neutrino oscillation experiments. The accurate modelling of the neutrino interactions requires more experimental observables to determine its accuracy. Adler Angles are observables carrying information about the polarization of the ?Δ resonance and the interference with the non-resonant single pion production. These observables were measured with limited statistics in bubble chamber experiments. We discuss the possibility of measuring the angles in neutrino interactions with nucleus.

Vapor Phase Mass Transfer in Partially-Saturated Porous Media
Creators: name: Corn, Fredrick E.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1989

description: Sampling of the partially-saturated zone at the site of regular, long-term dumping and burning of jet fuels revealed vapor-phase concentrations of volatile organic compounds up-gradient from the point of dumping. This suggests that significant amounts of volatile compounds may be transported through the partially-saturated zone by vapor-phase diffusion. The laboratory component of this research examined both the steady-state and transient diffusion behavior of toluene, a volatile organic compound, in 6-cm long columns packed with glass beads and soil. One end of a column was exposed to toluene vapor and the other was sampled periodically using an activated carbon trap. The results of these diffusion experiments, when compared to column diffusion simulated with a one-dimensional finite difference model, revealed a retardation effect during the approach to steady state. The retardation effect was attributed to vapor-aqueous and aqueous-solid phase partitioning. Linear sorption constants were determined for the experimental data using the finite difference model. Although there was some variability in the data from one set of column runs to another, one set of experiments run with soil at 50-70% of saturation, was closely approximated using a linear sorption coefficient consistent with the linear coefficient found for a saturated system in an independent batch experiment. Sorption parameters for the saturated system were determined with a bottle-point equilibrium study and a non-linear Freundlich sorption model was found to describe the saturated system more accurately than a linear model. For several of the diffusion columns however, the model, run with linear sorption parameters, predicted transient diffusion behavior that fit the experimental data well.

We illustrate our results by considering the dynamical behavior of the trace-distance correlations in multi-qubit systems under local dephasing and generalized amplitude damping.

The Effect of Relative Humidity on Toluene Adsorption by Activated Carbon
Creators: name: Owen, M. Kathleen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1996

description: Performance characteristics of activated carbon as a gas-phase air cleaner media under various levels of relative humidity and a range of toluene concentrations were examined. Toluene breakthrough curves at levels of humidity from below 5 to 80% were obtained. The concentration of the toluene challenge varied from 0.4 to 72.8 ppm. The experiments were performed in a small-scale test rig with temperature, flowrate, and humidity controls. The carbon beds tested were 1 in. (2.5 cm) deep. Both bubblers and cylinder gases were used to produce the challenge gas. These experiments provided data to explore the relationship of relative humidity (RH) to useful lifetime. RH has negligible influence on the adsorption of toluene below 50% RH. However by 75% RH, the toluene adsorption is decreased. For toluene challenges with RH above the inflection point in the relationship between the carbon bed water content and the RH of the challenge air, the water interferes with the adsorption of toluene. Thus the water adsorption curve correlates well with the toluene adsorption data. The linearity of the relationship between the concentration and the 10% breakthrough time indicates that high concentration breakthrough data can be used to predict the breakthrough time for lower concentration challenges. The linear relationship is shown for 50% or lower RH and for the 80% RH data.
Characterization of an Aerosol Chamber for Human Exposures to Endotoxin
Creators: name: Taylor, Lauralynn
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1997

description: The objective of this study was to develop and characterize an exposure chamber in which human subjects could be exposed to low concentrations of an endotoxin aerosol. In order to achieve this objective, an exposure chamber was designed, constructed, and characterized. The aerosol chamber was constructed by partitioning off an existing dust room in the Aerosol Laboratory. The chamber consisted of sealed cinder block, glass windows and Plexiglas with a volume of approximately 6.27 cubic meters. Dr. Robert Jacobs at the University of Alabama, used an acetone adhesion process to adsorb Enterobacter Agglomerans onto size specifc cellulose particles to create the endotoxin aerosol. After a significant evaluation period, an endotoxin-coated aerosol was consistently collected with a resulting concentration range of 1200-1500 ng endotoxin/mg dust. A consistent aerosol dispersal mechanism was developed to continually aerosolize the endotoxin material in the chamber. The dry powder dust generator, the Aeroreist, was refined to continually disperse small quantities of the aerosol in to the exposure chamber to maintain the dust concentrations at 250 μg/m[3]. Dust concentrations in the chamber were monitored with the Portable Continuous Aerosol Monitor (PCAM) Model 151 (ppm Inc, KnoxviUe, TN). Total dust and cascade impactor samples were also collected throughout exposure periods using a modified NIOSH 0500 method. The total dust concentrations obtained from these samples correlated with calibrated dust concentrations from the PCAM. Together the consistency of the total dust results, endotoxin concentrations, and monitoring instruments gave investigators significant confidence in the chamber characterization.

Non-Toxic Particulate Masks: A Quantitative Evaluation of Their Effectiveness During Paint Spraying Operations
Creators: name: Davis, David Sedgwick
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: It is commonly known that disposable dust masks offer a worker no protection from solvent vapors. However, they are frequently utilized during paint spraying operations. In one instance a workman wearing a disposable mask died from xylene poisoning while spray painting a boat outdoors. This study examined the possibility that the constant wetting of a dust mask during paint spraying may create an elevated solvent concentration in the breathing zone of a worker. Tests were conducted in a controlled laboratory system that determined simultaneous xylene concentrations in a mask and in the surrounding ambient air immediately following a paint spray of varying duration. Results consistently indicated a remarkably higher concentration inside the mask for the initial two minutes following the spray of paint. The theoretical dose was as much as 86% greater inside the mask as compared to outside the mask during those two minutes.

description: Freezing colloidal suspensions widely exists in nature and industry. Interface instability has attracted much attention for the understandings of the pattern formation in freezing colloidal suspensions. However, the interface instability modes, the origin of the ice banding or ice lamellae, are still unclear. In-situ experimental observation of the onset of interface instability is still absent up to now. Here, by directly imaging the initial transient stage of planar interface instability in directional freezing colloidal suspensions, we proposed three interface instability modes, Mullins-Sekerka instability, global split instability and local split instability. All the three instability modes come from the competition of the solute boundary layer and the particle boundary layer, which only can be revealed from the initial transient stage of planar instability in directional freezing.

Selective Separation of Eu3+ Using Polymer-Enhanced Ultrafiltration

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: The U.S. Department of Energy is actively pursuing new and improved separation techniques to concentrate high-level liquid radioactive waste, particularly at the Hanford Site, in order to minimize the waste volume requiring vitrification. A process to selectively remove [241]Am from liquid radioactive waste was investigated as an actinide separation method that could be applicable to Hanford and other waste sites. The experimental procedures involved removal of Eu, a nonradioactive surrogate for [241]Am, from aqueous solutions at pH 5 using organic polymers in conjunction with ultrafiltration. Commercially available polyacrylic acid (60,000 MW) and Pacific Northwest Laboratory's (PNL) synthesized E3 copolymer (-10,000 MW) were tested. Test solutions containing 10 μg/mL of Eu were dosed with each polymer at various concentrations in order to bind Eu (i.e., by complexation and /or cation exchange) for subsequent rejection by an ultrafiltration coupon. Test solutions were filtered with and without polymer to determine if enhanced Eu separation could be achieved from polymer treatment. Both polymers significantly increased Eu removal. The optimum concentrations were 20 μg/mL of polyacrylic acid and 100 μg/mL of E3 for 100% Eu rejection by the Amicon PM1O membrane at 55 psi. In addition to enhancement of removal, the polymers selectively bound Eu over Na, suggesting that selective separation of Eu was possible. The results of this study suggest that polymer-enhanced ultrafiltration is a potential process for separation of [241]Am from Hanford tank waste. Thus, further investigation of binding agents and membranes effective under conditions similar to the tank waste (e.g., very alkaline and high ionic strength) is warranted. This process also has potential applications for selective separation of metals from industrial process streams and the use of the polymers evaluated in this study and other high molecular weight binding agents that exhibit an affinity for regulated toxic metals should be further examined.
An Investigation of Radon in North Carolina Groundwater and Its Relationship To Rock Type
Creators: name: Loomis, Dana P.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: Previous studies of radon-222 in North Carolina groundwater supplies have shown that the state has some of the highest radon concentrations in the United States. Reanalysis of existing environmental sampling data from 272 public water systems shows that the distribution of radon in North Carolina follows distinct geographical and geological patterns; a simple average concentration based on these samples would not provide a meaningful estimate of public exposure to radon. Variations in radon concentration are associated, in particular, with rock type. The highest radon concentrations in North Carolina groundwater supplies are found in waters from areas in the Piedmont and Blue Ridge regions underlain by granites, and the lowest concentrations (generally < 500 pCi/1) occur in aquifers of the coastal plain. Concentrations in most of the Piedmont region are intermediate (generally between 1000 and 5000 pCi/1). There appears to be no systematic relationship between radon concentration and water system size in North Carolina.

description: In this paper we investigate the loading and unloading behavior of soft solids in adhesive contact with randomly rough profiles. The roughness is assumed to be described by a self-affine fractal on a limited range of wave-vectors. A spectral method is exploited to generate such randomly rough surfaces. The results are statistically averaged, and the calculated contact area and applied load are shown as a function of the penetration, for loading and unloading conditions. We found that the combination of adhesion forces and roughness leads to a hysteresis loading-unloading loop. This shows that energy can be lost simply as a consequence of roughness and van der Waals forces, as in this case a large number of local energy minima exist and the system may be trapped in metastable states. We numerically quantify the hysteretic loss and assess the influence of the surface statistical properties and the energy of adhesion on the hysteresis process.

Application of Contaminant Fate and Transport Models in Saturated Soil
Creators: name: Gilbertsen, Robert H.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1987

description: Systems that remediate an aquifer by purging contaminated water often operate for prolonged periods because contamination stubbornly lingers. This is the tailing phenomenon. For nondegradable, nonionic organics in ground water, sorption is the prominent reaction. Sorption is crucial to the tailing phenomenon. Types of sorption rate expressions include (1) local equilibrium, (2) Langmuir second order, (3) equilibrium/first order, and (4) dual resistance sorption. Types of equilibrium isotherms include (1) linear, (2) Freundlich, or (3) Langmuir equilibrium. This work improves four existing contaminant transport simulator models; each model incorporates one sorption rate assumption. Based on modeling of the ground water contaminant nitrobenzene on Ann Arbor granular aquifer material in laboratory soil column reactors, the rate-controlled models predict contaminant breakthrough better than the local equilibrium models. In one field-scale simulation all nonlinear and nonequilibrium models display the tailing phenomenon. The linear local equilibrium model does not.

description: About 34 percent of U.S. farms in 1997 used hired labor, and 12 percent used contract labor. Hired labor costs averaged 12 percent of total farm production expenses in 1997, but amounted to as much as 44 percent of production expenses for horticultural specialty crop producers, 40 percent for fruit and tree nut producers, and 32 percent for vegetable and melon producers. Hired farmworkers have accounted for about 31 percent of the farm workforce in the 1990's. Hired labor's importance to U.S. farm production requires agricultural employers to understand Federal laws and regulations governing employment, taxes, wages, and working conditions. This single-source publication summarizes these laws and regulations. This updated version of a 1992 report contains expanded sections on agricultural employers' Federal safety requirements, migrant and seasonal farmworker provisions, and tax requirements for agricultural employers, as well as new sections on employer responsibilities under the Family and Medical Leave Act of 1993 and the Personal Responsibility and Work Opportunity Reconciliation Act of 1996.

description: Athletes are required to perform in variable, unpredictable and high stress environments that demand a high degree of domain-general and domain specific cognitive and physical abilities. To achieve this performance, athletes have trained to become high skills in solving sport-specific movement problems. Skill acquisition is the enduring changes in voluntary control over movements of joints and segments in an effort to solve a motor skill problem and achieve a task goal that accompany the learning of a motor task (Magill, 2010). Therefore, sport skill acquisition research aims to find interventions that are most effective for the improvement of skills in athletes.
Bundle formation in parallel aligned polymers with competing interactions

description: Aggregation of like-charged polymers is widely observed in biological and soft matter systems. In many systems, bundles are formed when a short-range attraction of diverse physical origin like charge-bridging, hydrogen-bonding or hydrophobic interaction, overcomes the longer- range charge repulsion. In this Letter, we present a general mechanism of bundle formation in these systems as the breaking of the translational invariance in parallel aligned polymers with competing interactions of this type. We derive a criterion for finite-sized bundle formation as well as for macroscopic phase separation (formation of infinite bundles).

description: There is an intimate relation between entanglement entropy and Riemann surfaces. This fact is explicitly noticed for the case of quadratic fermionic Hamiltonians with finite range couplings. After recollecting this fact, we make a comprehensive analysis of the action of the Möbius transformations on the Riemann surface. We are then able to uncover the origin of some symmetries and dualities of the entanglement entropy already noticed recently in the literature. These results give further support for the use of entanglement entropy to analyse phase transition.

Testing of a Model to Estimate Vapor Concentration of Various Organic Chemicals
Creators: name: Bakalyar, Stephen M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1990

description: A model developed by Dr. Parker C. Reist to predict the build-up and decay rates of vapor concentrations following a chemical spill and clean-up was tested. The chemicals tested were: acetone, butyl acetate, ethyl acetate, hexane, methylene chloride, methyl ethyl ketone, and toluene. The evaporation rates of these chemicals were determined both by prediction, using a model developed by I. Kawamura and D. Mackay, and empirically and these rates were used in the Reist model. Chamber experiments were done to measure actual build-up and decay of vapor concentrations for simulated spills and simulated clean-up. The chamber experimental results were compared to the model's predicted results. The Reist model, used with the Kawamura-Mackay predicted evaporation rate, can be useful in estimating equilibrium concentration and the time required to reach the equilibrium concentration.
