Incorporating Consideration of Location, Compliance, and Reliability into Estimates of Brackish Resource Development Costs
Creators: name: Traviglia, Andrea M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004

description: An analysis is undertaken to evaluate the total costs of augmenting water supply through desalination of brackish water sources as compared to freshwater sources. Although membrane desalination is generally more expensive than conventional treatment, consideration should also be given to costs related to source location, regulatory compliance and supply reliability. Consideration of these additional factors has been largely unexplored in previous cost comparisons. This project involves the development of an approach which will enable communities to integrate such additional factors into their decision-making. Fresh water and brackish water sources are compared in terms of the "total cost of supply and treatment", which includes costs of acquisition, treatment to maintain regulatory compliance, and storage. The costs considered begin with the withdrawal of raw water at the source and end when the treated water enters the distribution system. Results show that the economic viability of utilizing brackish resources increases when the total costs of supply and development are compared, especially for smaller capacity plants. Conveyance costs associated with more distant sources can quickly reduce the cost gap between membrane desalination and conventional treatment when comparing a local brackish source with a more distant freshwater source. Additionally, many conventional systems will require upgrades and/or process additions to achieve compliance with new standards (e.g. disinfection byproducts, arsenic), whereas membrane desalination processes are often able to meet new and existing standards with little modification. Therefore, the consideration of regulatory compliance can further reduce the cost gap between brackish and freshwater sources. Finally, in many water scarce areas, brackish sources may be underdeveloped relative to freshwater supplies and thus are likely to provide more reliable yields, resulting in lower capital costs through a reduction in the capacity of required storage infrastructure. A sensitivity analysis is also conducted to determine which factors have the greatest impact on the total supply and treatment costs. Through use of this approach, communities facing difficult decisions will be able to more comprehensively compare the costs of augmenting water supply through desalination with those of alternative supplies.

description: The aim of this paper is to illustrate how vulnerable bit preservation is, regardless of how well prepared you think you are, and hopefully to inspire other institutions that may face similar challenges at some point. At the same time, this paper illustrates the importance of research in digital preservation and the need for conferences like iPRES to enable communication about relevant practical experiences and research results. The paper includes an illustrative story about how parts of the Danish digital cultural heritage was rescued after being endangered by accumulating political, environmental and organizational events, and where the final solution involves outsourcing parts of the bit preservation solution. The story includes a description of how the bits were rescued by different means. Firstly, by using research results to convince political management that bit preservation is much more than a storage solution that can be outsourced. Secondly, by initiating various actions to re-establish the wanted level of bit safety. And thirdly, by establishing a contractual and procedural basis for outsourcing parts of the bit preservation. Award Winner: This paper won the iPres 2018 Best Long Paper Award

description: Big datasets are becoming increasingly important in astrophysics due to new surveys continuously observing our night sky. A prominent example of an observatory that will produce a large data stream is Vera C. Rubin LSST, designed to simultaneously monitor the southern night sky in six colors. Unsupervised machine learning (ML), a method of learning from patterns within the data, is key for gaining insight into this expansive photometric data. We present our prototype classifier dedicated to classifying RR Lyrae variable stars into their relevant subclasses (RRab, RRc, and RRd). Using the RR Lyrae catalog of the ESA Gaia mission, we constructed training sets containing ~30,000 light curves using data from the Zwicky Transient Facility Catalog of Periodic Variable Stars (ZTF CPVS) and light curves extracted from full-frame images of the NASA TESS space telescope. Using a Variational Autoencoder (VAE), we project the processed light curves into a low-dimensional representation, which quantitatively describes the characteristic shape elements of the light curves. In preparation for Rubin LSST, we applied our pipeline to ZTF, a precursor facility for Rubin LSST. We show how the ML results are improved by including physical features such as period and variation amplitude. Through unsupervised clustering of this data representation, we identified the RR Lyrae subclasses in the ZTF data, which we anticipate to be easily adaptable to Rubin LSST.

description: Die vorliegende Arbeit stellt für die Bildwissenschaften eine methodische Grundlage dar, Kleidung im Bild als Konstruktion zu begreifen und zu interpretieren. Anhand der eindrucksvollen Patronageprojekte der Familie Tornabuoni – einer gerade emporgestiegenen Kaufmannsfamilie im Umkreis der Medici – werden die Möglichkeiten und Grenzen von symbolischer Kommunikation in der Florentiner Frühneuzeit untersucht. Unter anderem über Symbole wurde die Position im Gesellschaftsgefüge des unsicheren frühneuzeitlichen Regierungsklimas immer wieder neu hergestellt und von Neuem ausgehandelt. Die gewählte Bildgarderobe ist dafür ein hervorstechendes Beispiel.
description: The thesis presents an art historical methodology that assesses clothing and its pictorial representations in order to interpret how material culture relates to social construction. Using as an example an impressive patronage project of the Tornabuoni family – a newly rich family of merchants in the circle of the Medici – reveals the possibilities as well as the limitations of symbolic communication through dress in early modern Florence. In addition to outward style, these subtle symbols helped to establish and renegotiate their bearer’s position in the shifting hierarchy of an uncertain political climate. By closely examining Tornabuoni commissions, the thesis demonstrates how clothing is a critical means of understanding social motivations and aspirations.

Femtosecond Laser Mass Spectroscopy of Cyclic Aromatic Hydrocarbons

description: Cyclic Aromatic molecules are the subject of continued research due to their highly advantageous characteristics which can be exploited in the areas of pharmaceuticals, material science and nano-electronics. While the defining properties and criteria for a molecule to be considered aromatic are very specific and well established, the degree of aromaticity of these molecules and their corresponding ordering remains a source of continued debate. Given that the macroscopic aromatic properties are fundamentally rooted in the underlying electronic structure and molecular dynamics, these properties can be probed in numerous ways. One such method is to exploit the strong laser field as it pertains to non-linear light-matter interaction. More specifically, the study of photoionization, as a direct resultant effect of strong field light-matter interaction, gives us direct insight into electronic and spatial properties as captured via mass spectroscopy. As a strong-field process, photoionization is effective because the variables that influence its results are also the ones that define aromaticity thus a correlation can be postulated. Other strong field advanced techniques to probe aromacity such as High Harmonic Generation (HHG) have already been successful shown by our group to be effective spectroscopic tools. In this way, photoionization provides supporting evidence to enhance the understanding of these novel spectroscopic tools. This thesis demonstrates that photoionization mass spectroscopy can be used as a probe into the aromaticity order of 5-membered cyclic aromatic molecules. Furthermore, the thesis will show that photoionization results correlate with the previously conducted HHG studies in this area thus further supporting these techniques as sensitive spectroscopic tools into aromaticity. The first part of this thesis describes the characterization of aromatic molecules and the corresponding process to obtain photoionization results that can be correlated to aromaticity. In the second part, these results are compared to the theoretical model and HHG demonstrating consistent results. The third and final component of this thesis describes future work, namely two-colour control of photoionization which is intended to provide greater resolution and variation of photoionization spectra thereby providing a more comprehensive and conclusive understanding of the proposed correlation with aromaticity.

description: We study the confinement-deconfinement phase transition of pure Yang-Mills theories at finite temperature using a simple massive extension of standard background field methods. We generalize our recent next-to-leading-order perturbative calculation of the Polyakov loop and of the related background field effective potential for the SU(2) theory to any compact and connex Lie group with a simple Lie algebra. We discuss in detail the SU(3) theory, where the two-loop corrections yield improved values for the first-order transition temperature as compared to the one-loop result. We also show that certain one-loop artifacts of thermodynamical observables disappear at two-loop order, as was already the case for the SU(2) theory. In particular, the entropy and the pressure are positive for all temperatures. Finally, we discuss the groups SU(4) and Sp(2) which shed interesting light, respectively, on the relation between the (de)confinement of static matter sources in the various representations of the gauge group and on the use of the background field itself as an order parameter for confinement. In both cases, we obtain first-order transitions, in agreement with lattice simulations and other continuum approaches.

description: The geologic and hydrologic characteristics of low-level radioactive waste (LLRW) disposal sites in the eastern United States are reviewed in this technical report. Since North Carolina has been designated as the next host for a LLRW faciltiy by the Southeast Compact Commission, this information coupled with the geology/hydrology of North Carolina can be used in the identification of potential siting constraints. In North Carolina, engineered barriers will be incorporated into the selected LLRW technology. In this report concrete degradation mechanisms are reviewed. Based on this information, possible geologic/hydrologic constraints of siting a LLRW disposal facility in North Carolina are discussed.

Drug resistance

description: Multidrug resistance has become a major issue in the treatment of both microbial infections and cancers. While genetically encoded drug resistance is fairly well understood, it cannot explain all observed cases of resistance, namely the ability of a subset of disease cells to persist in an otherwise susceptible population. This non-genetic resistance requires the heterogeneous expression of a drug resistance phenotype, which can be produced by certain gene regulatory network architectures. Two particular network motifs, the coherent feedforward loop (CFFL) and the positive feedback loop (PFL), have functional properties that implicate them in the development of non-genetic heterogeneity and response to changing conditions. Motivated by the observation that CFFL and PFL motifs are involved in the transcriptional regulation of multiple pleiotropic drug resistance (PDR) genes in yeast, it has been hypothesized that CFFLs and PFLs could contribute to the development of drug resistance. This hypothesis was based on model simulations and has not been tested experimentally. In this thesis, it is demonstrated experimentally that the PDR5 gene is indeed expressed heterogeneously within an isogenic population of yeast cells, and that this cell-to-cell variability enables a subset of cells to persist drug treatment. While these observations agree with model predictions, it is also observed that the resistant phenotype occurs within a subset of cells that are morphologically distinct. This subpopulation has previously been linked to abnormal mitochondrial function, which cannot be ruled out as a likely cause of the observed drug resistance. To validate the hypothesis that CFFLs and PFLs contribute to drug resistance, the expression of the PDR5 gene was placed under the control of synthetic gene regulatory networks constructed to contain different combinations of direct activation, indirect activation, and positive feedback. These networks are used to show that direct activation can provide a selective advantage enabling rapid responses, while indirect activation and positive feedback can provide a selective advantage by maintaining favourable gene expression states. These results demonstrate that a gene regulatory network combining CFFLs and PFLs can contribute to the development of drug resistance, and highlight plausible means by which cells can exploit certain network features to gain a fitness advantage.

description: We present ab initio predictions for ground and excited states of doubly open-shell fluorine and neon isotopes based on chiral two- and three-nucleon interactions. We use the in-medium similarity renormalization group, in both flow-equation and Magnus formulations, to derive mass-dependent sd valence-space Hamiltonians. The experimental ground-state energies are reproduced through neutron number N=14, beyond which a new targeted normal-ordering procedure improves agreement with data and large-scale multi-reference calculations. For spectroscopy, we focus on neutron-rich 23-26F and 24-26Ne isotopes near N=14,16 magic numbers. In all cases we find an agreement with experiment competitive with established phenomenology. Moreover, yrast states are well described in 20Ne and 24Mg, providing an ab initio description of deformation in the medium-mass region.

Smoothing parameter and model selection for general smooth models

description: This paper discusses a general framework for smoothing parameter estimation for models with regular likelihoods constructed in terms of unknown smooth functions of covariates. Gaussian random effects and parametric terms may also be present. By construction the method is numerically stable and convergent, and enables smoothing parameter uncertainty to be quantified. The latter enables us to fix a well known problem with AIC for such models. The smooth functions are represented by reduced rank spline like smoothers, with associated quadratic penalties measuring function smoothness. Model estimation is by penalized likelihood maximization, where the smoothing parameters controlling the extent of penalization are estimated by Laplace approximate marginal likelihood. The methods cover, for example, generalized additive models for non-exponential family responses (for example beta, ordered categorical, scaled t distribution, negative binomial and Tweedie distributions), generalized additive models for location scale and shape (for example two stage zero inflation models, and Gaussian location-scale models), Cox proportional hazards models and multivariate additive models. The framework reduces the implementation of new model classes to the coding of some standard derivatives of the log likelihood.

Effects of Ambient Particulate Matter on Cytokine Production in Mouse Macrophages and Epithelial Cells
Creators: name: Boyles, Rebecca Rosenblatt

Year: 2008

description: The objective of the Multi-Site Ambient Particle Study (MAPS) was to collect ambient particles from different geographical regions, examine their health effects using various in vitro and in vivo experimental approaches, and ultimately relate the health effects to particle components and pollution sources. Size fractionated airborne particles were collected in six different locations in the United States and made available to investigators in several different laboratories. The objective of this study is to compare the effects of these ambient particles on cytokine production in different lung cell types using in vitro models of mouse macrophages and lung epithelial cells. Briefly, MH-S cells, a mouse lung macrophage cell line, and LA-4 cells, a mouse lung epithelial cell line, were exposed to 10 or lOO μg/ml of either the coarse or fine particle fraction and examined for IL-6 expression 24 hours post-exposure. Both coarse and fine particle fractions dose-dependently up regulated IL-6 production in MH-S cells and these responses varied moderately with geographical location. Interestingly, the coarse fraction induced significantly greater IL-6 production in MH-S cells than the fine fraction, independently of geographical location. In contrast, both fine and coarse particle fractions up regulated IL-6 production in LA-4 cells and the magnitude of these responses varied with collection site. Taken together, these results indicate that regardless of geographic location, coarse and fine particle fractions exert different effects in lung macrophages and epithelial cells, with epithelial cells being more susceptible to health effects induced by fine particle fractions. In addition, our analysis suggests that geographical collection site may affect the health effects in different lung cell types, but the sources for this and their interactions are complex. Data obtained from this study will help distinguish the role of different lung cell types in particle-induced health effects seen in vivo.

description: This thesis considers a common healthcare challenge of planning capacity for a system of care where patients receive multiple treatments sessions from multiple resources. As a case study of this more general problem, we considered the particular context of a capacity planning model for the Mood and Anxiety Program at The Ottawa Royal Health Centre (referenced as The Royal for simplicity) where a new service system known as CAPA (www.capa.co.uk) is being implemented to enhance the mental care provided to its patients. In order to develop the capacity planning model, we have created a simulation model using the Arena simulation software. We have also used the ABCMod Framework as the modeling methodology. The ABCMod is an activity based conceptual modelling framework that provides a set of guidelines as to how to build a conceptual model including its structural and behavioural aspects as well as a collection of constructs which include inputs, outputs and parameters among others. The ABCMod framework tools are expected to facilitate the model validation with project stakeholders. A series of scenarios relevant to The Royal were modeled and analyzed in order to determine how best to manage capacity so certain performance goals within the CAPA system implementation are met. These scenarios determine the service level The Royal can provide with its current capacity and also the amount and distribution of resources that is required to achieve its goals under the CAPA system. As a result of our simulation runs, we defined the policy implications for The Royal in order to achieve its targets and successfully implement CAPA. Additionally, through the application of the ABCMod framework and standard process mapping tools, we were able to reach a consensus and validate our modeling approach with the project stakeholders at The Royal. Our model could be adapted to other settings in which multiple resources provide a series of sequential interventions to clients.

description: Cell encapsulation is a promising concept in regenerative medicine and stem cell treatment of diseases. Cells encapsulated in hydrogels have shown to yield better therapeutic outcome over cells in suspension. Microfluidic platforms have facilitated the process of cell encapsulation through the controlled mixing of aqueous cell solution and hydrogel with an immiscible liquid to yield a monodispersed population of microcapsules at a high throughput. However, given that the microfluidic process of placing cells in microcapsules is completely random, yielded samples are often riddled with empty microcapsules, raising the need for a post-encapsulation purification step to sort empty microcapsules from cell-laden ones. Sorting of microcapsules can be achieved through several techniques, most desirable of which are electrokinetic such as dielectrophoresis (DEP) and electrophoresis (EP). The advantages of DEP and EP techniques are that they support label-free sorting and yield a high throughput. However to achieve true effective DEP or EP sorting, there is a need to understand how empty microcapsules react to these electrokinetic forces versus occupied microcapsules. This study developed microfluidic devices for characterising the electrokinetic effects on microcapsules using DEP and EP. Results of both characterization techniques showed notable differences in the response of empty microcapsules versus cell-laden ones, reinforcing their potentials for sorting. Furthermore, this study proposed designs for microcapsules sorting devices that leverage EP and DEP.
Evaluation of an Alternate Sampling Device for Inside the Respirator Facepiece
Creators: name: Ebert, Julie A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1998

description: Historically, the predominant sampling device for quantitative respirator fit testing has been a "standard" mask probe inserted through the front of the respirator. This probe was first developed by Dr. Ben Liu at the University of Minnesota and is widely used in quantitative respirator fit testing.An alternate sampling device, a cannula probe, has been used in place of the mask probe in respirator studies conducted at the Lawrence Livermore National Laboratory. The purpose of this study was to validate the previous research performed and give researchers the option of using a cannula probe, by comparing the sampling capabilities of the cannula with those of the mask probe. The cannula probe is a hospital-like nasal cannula, positioned between the nose and the upper lip of the subject with the probes pointed outward. The mask and cannula probes sampled aerosol concentrations inside the same respirator face piece. The conditions of the experiment were varied to determine the affect of different protection factors, respiration rates, and leak locations. The measured mean protection factors using the mask and cannula probes were compared through the application of a regression model. The cannula probe measured a slightly higher concentration of aerosol, resulting in a slightly lower protection factor, than the mask probe. Overall, the two probes were found to be comparable sampling devices with a very strong linear relationship. A potential use of the cannula probe, in place of the mask probe, may be in respirator studies where the respirator is loose fitting.

We study these theories using anomalies and $c$-extremization. The gravitational duals to these fixed points are new AdS$_3$ solutions of IIB supergravity which we exhibit explicitly. Along the way we uncover a universal relation between the conformal anomaly coefficients of four-dimensional and two-dimensional SCFTs connected by an RG flow across dimensions. We also observe an interesting novel phenomenon in which the superconformal R-symmetry mixes with baryonic symmetries along the RG flow.

description: We consider a downlink cellular network where multi-antenna base stations (BSs) transmit data to single-antenna users by using one of two linear precoding methods with limited feedback: (i) maximum ratio transmission (MRT) for serving a single user or (ii) zero forcing (ZF) for serving multiple users. The BS and user locations are drawn from a Poisson point process, allowing expressions for the signal- to-interference coverage probability and the ergodic spectral efficiency to be derived as a function of system parameters such as the number of BS antennas and feedback bits, and the pathloss exponent. We find a tight lower bound on the optimum number of feedback bits to maximize the net spectral efficiency, which captures the overall system gain by considering both of downlink and uplink spectral efficiency using limited feedback. Our main finding is that, when using MRT, the optimum number of feedback bits scales linearly with the number of antennas, and logarithmically with the channel coherence time. When using ZF, the feedback scales in the same ways as MRT, but also linearly with the pathloss exponent. The derived results provide system-level insights into the preferred channel codebook size by averaging the effects of short-term fading and long-term pathloss.

A Case-Control Study of Diarrhea, Water and Sanitation in Rural Malawi
Creators: name: Young, Beverly A.

description: An epidemiologic case-control study was conducted to test 1) the hypothesis that improved water and sanitation would reduce diarrheal incidence in children under five years of age, and 2) the feasibility of using a case-control design to evaluate health impacts of environmental interventions. Both improved water sources and access to latrines were associated with increased rather than decreased diarrhea incidence except when the children were exclusively breastfed. This increased incidence may be the result of diminishing or delayed immunity to diarrheal diseases when sanitation and water facilities are improved. The results show the need for health interventions which couple improved environmental services and food hygiene. The significance of the findings are limited due to the poor precision of the estimates of the effect measures. Strong interactions between water, sanitation and breastfeeding would necessitate a sample size at least four times larger than what was used. Future case-control studies on diarrheal morbidity should anticipate such interactions and increase sample sizes to detect changes in diarrheal incidence which would be of public health significance.

description: Topological insulators are a novel class of quantum matter with a gapped insulating bulk yet gapless spin helical Dirac fermion conducting surface states. Here, we report local and non-local electrical and magneto transport measurements in dual-gated BiSbTeSe2 thin film topological insulator devices, with conduction dominated by the spatially separated top and bottom surfaces, each hosting a single species of Dirac fermions with independent gate control over the carrier type and density. We observe many intriguing quantum transport phenomena in such a fully-tunable two-species topological Dirac gas, including a zero-magnetic-field minimum conductivity close to twice the conducatance quantum at the double Dirac point, a series of ambipolar two-component half-integer Dirac quantum Hall states and an electron-hole total filling factor zero state (with a zero-Hall plateau), exhibiting dissipationless (chiral) and dissipative (non-chiral) edge conduction respectively. Such a system paves the way to explore rich physics ranging from topological magnetoelectric effects to exciton condensation.

Potential functional variants in AHR signaling pathways are associated with age at puberty in swine

description: Reproductive failure accounts for about a third of sow removals and most of these removals are animals in lower parities. Gilts that reach puberty earlier tend to stay in the herd longer and be more productive. Genetic improvement of reproductive traits in pigs has been challenging because these traits are sex-limited, have low heritabilities, are not expressed until later in the animal’s life and are not routinely measured in industry settings. Selecting on causal genetic variants that affect these traits would greatly accelerate genetic progress. This study tested for genetic associations of protein-coding variants in candidate genes identified in genome-wide association studies. Ten amino acid changes or variants in six candidate genes were found to be associated with age at puberty. These variants may be causative mutations that influence age at puberty in gilts and possibly sow lifetime productivity.
Removal of Ozone by the Extrathoracic and Intrathoracic Airways in Man
Creators: name: Weaver, Richard A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: Extrathoracic and intrathoracic ozone removal were studied in eighteen healthy, nonsmoking volunteers using a controlled environmental chamber. Ozone-containing air was drawn through a polyethylene sampling tube placed through one nostril into the posterior pharynx, and analyzed with a rapidly responding ozone analyzer. Measurements were made using a randomized split-split plot design for each subject at ozone concentrations of 0.1 ppm, 0.2 ppm and 0.4 ppm, using three breathing modes (nasal, oronasal and mouth), and at two different breathing frequencies (12 and 24 BPM). For extrathoracic ozone removal, significant effects were demonstrated for mode of breathing and breathing frequency (both with p< 0.001), but not for ambient ozone concentration. For intrathoracic ozone removal, significant effects were demonstrated for ambient ozone concentration (p=0.032) and for breathing frequency (p<0.001), but not for mode of breathing. Mechanisms are postulated to explain the results obtained.

description: Weather derivatives are contingent claims with payoff based on a pre-specified weather index. Firms exposed to weather risk can transfer it to financial markets via weather derivatives. We develop a utility-based model for pricing baskets of weather derivatives in over-the-counter markets under counterparty default risk. In our model, agents maximise the expected utility of their terminal wealth, while they dynamically rebalance their weather portfolios over a finite investment horizon. Via partial market clearing, we obtain semi-closed forms for the equilibrium prices of weather derivatives and for the optimal strategies of the agents. We give an example on how to price rainfall derivatives on selected stations in China in the universe of a financial investor and a weather exposed crop insurer.
