Simulating Random Packing of Porous Media
Creators: name: Yang, Aiwei
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1995

description: The microstructure of porous media strongly influences the motion and distribution of fluids in the pore space. Although considerable effort has been made to incorporate pore-level phenomena and pore structure data into network micromodels of pore space for prediction of macroscopic flow behavior, quantitative information on pore geometric configuration is required to test the validity of the theoretical models. Given our lack of knowledge of pore-scale characteristics (e.g., pore body, pore throat size distributions, and coordination number distributions) to capture the complexity of microstructure in porous media, random packing research can provide the necessary conceptual and quantitative basis for the network model development. This work contributes to these efforts by developing a computer algorithm that generates random or correlated packing realizations of porous media systems quickly and rigorously. Porous media are modeled as random packings of spheres with specified porosities, log-normal particle sized distributions and spatial correlations. The packings are gravitationally stable and range from random loose packing to random close packing. The packing porosity for both close and loose packed lattices decreases when the standard deviation of the sphere radius size distribution increases. The mean coordination number for both types of packings remains stable when the standard deviation is less than 0.4, but steadily decreases when the standard deviation is greater than 0.4. Tests of simulation size effects show that both the packing porosity and mean coordination number reach plateaus when the number of packed spheres is greater than 3x10[4] in the purely random packing. When packing with spatial correlation, however, the size at which these two properties attain constant states is highly dependent upon correlation length, standard deviation and domain size. Results of spatially correlated random packings demonstrate that great statistical fluctuation exists as the ratio of correlation length to domain length is greater than 0.1.

description: We study nilpotency in the context of exact Mal'tsev categories taking central extensions as the primitive notion. This yields a nilpotency tower which is analysed from the perspective of Goodwillie's functor calculus. We show in particular that the reflection into the subcategory of $n$-nilpotent objects is the universal endofunctor of degree $n$ if and only if every $n$-nilpotent object is $n$-folded. In the special context of a semi-abelian category, an object is $n$-folded precisely when its Higgins commutator of length $n+1$ vanishes.

description: We present an efficient proposal for error-rejecting quantum computing with quantum dots (QD) embedded in single-sided optical microcavities based on the interface between the circularly polarized photon and QDs. An almost unity fidelity of the quantum entangling gate (EG) can be implemented with a detectable error that leads to a recycling EG procedure, which improves further the efficiency of our proposal along with the robustness to the errors involved in imperfect input-output processes. Meanwhile, we discuss the performance of our proposal for the EG on two solid-state spins with currently achieved experiment parameters, showing that it is feasible with current experimental technology. It provides a promising building block for solid-state quantum computing and quantum networks.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: Enzymatic treatment has been shown to be effective for removal of a variety of chemicals in aqueous solution, however little research has been completed on enzymatic oxidation of 'real' industrial wastewaters. The purpose of this research project was to evaluate the application of Coprinus macrorhizus peroxidase in reducing the phenol concentration in an actual high-strength industrial wastewater. The wastewater was raw distillate from a phenol-formaldehyde manufacturing process. The specific objectives of this study were: to characterize the waste stream sample; to evaluate enzyme kinetics, including the kinetics of inactivation; to evaluate factors that affect enzyme-catalyzed oxidation, such as pH, enzyme concentration, substrate concentration, interfering compounds, and reactor configuration; and, to optimize phenol removal while minimizing treatment cost. For comparison purposes, Fenton's reaction (ferrous iron and hydrogen peroxide) was also studied as a treatment option for the wastewater. Reagent consumption and potential cost of each treatment process were compared.

title: Efficiency of positive event dependence models for self-controlled case series designs
Creators: name: Shin, Gwangseop
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: The self-controlled case series (SCCS) design is an outcome-dependent sampling design developed to investigate potential associations between time-varying exposures and adverse recurrent events in clinical settings. It is a case-only design, in which only cases, who are individuals experienced the event-of-interest at least one time, are included. The cases serve as their own controls. As a result, the SCCS design implicitly controls for all time-fixed confounders. The standard SCCS method is based on a conditional Poisson process model, which cannot be used to model the effects of past event occurrences. A new method, called positive event dependence self-controlled case series (PD-SCCS), has been proposed to deal with this issue. This method adjusts the baseline intensity function of an event process with the number of previous events, and maintains all features of the SCCS method. In this study, we consider rare recurrent events settings, where the events are generated from mixed nonhomogeneous pure birth models with immigration. We investigate the relative efficiency of the PD-SCCS design compared to other SCCS and cohort designs in the estimation of the relative incidence parameter, as well as impacts of some model misspecifications and violations of model assumptions required for the PD-SCCS design through extensive Monte Carlo simulation studies. We illustrate the methods by analyzing a dataset from a clinical vaccine study, as well as two synthetic datasets based on a postmarketing drug safety surveillance study.

description: Linear mixed-effects models have increasingly replaced mixed-model analyses of variance for statistical inference in factorial psycholinguistic experiments. Although LMMs have many advantages over ANOVA, like ANOVAs, setting them up for data analysis also requires some care. One simple option, when numerically possible, is to fit the full variance-covariance structure of random effects (the maximal model; Barr et al. 2013), presumably to keep Type I error down to the nominal alpha in the presence of random effects. Although it is true that fitting a model with only random intercepts may lead to higher Type I error, fitting a maximal model also has a cost: it can lead to a significant loss of power. We demonstrate this with simulations and suggest that for typical psychological and psycholinguistic data, higher power is achieved without inflating Type I error rate if a model selection criterion is used to select a random effect structure that is supported by the data.

description: Several studies have combined heat and gravitational energy exchanges to create novel heat engines. A common theoretical framework is developed here to describe thermogravitational cycles which have the same efficiencies as the Carnot, Rankine or Brayton cycles. Considering a working fluid, enclosed in a balloon, inside a column filled with a transporting fluid, the cycle is composed of four steps. Starting from the top of the column, the balloon goes down by gravity, receives heat from a hot source at the bottom, rises and delivers heat to a cold source at the top. Unlike classic power cycles which need external work to operate the compressor, thermogravitational cycles can operate as "pure power cycle" where no external work is provided to drive the cycle. To illustrate this concept, the prototype of a thermogravitational electrical generator is presented. It uses a hot source of low temperature (average temperature near 57°C) and relies on the gravitational energy exchanges of an organic fluorinated fluid inside a balloon attached to a magnetic marble producing an electromotive force of 50 mV peak to peak by the use of a linear alternator. This heat engine is well suited to be operated using renewable energy sources such as geothermal gradients or focused sunbeams.

Year: 1988

description: Chemical waste minimization techniques applicable to biomedical research facilities were identified and evaluated with respect to current chemical management practices at NIEHS. A chemical waste audit was carried out in two phases: total waste management and high volume solvent. Current practices that enhance waste minimization include protocol review, substitution, incineration and waste handling education. Audit values indicate a high potential to reduce hazardous waste generation by also employing solvent recycling. Further education of researchers on the issue of chemical waste management and chemical material use accountability are identified as means to increase the Institute's waste reduction potential.

Non-reproductive dispersal: An important driver of migratory range dynamics and connectivity

description: Dispersal is the primary ecological process underpinning spatial dynamics in motile species by generating flux in reproductive locations over time. In migratory species, dispersal can also occur around non-breeding ranges, but this form currently lacks a unifying theoretical framework. We present a novel conceptual model for dispersal in migrants that builds upon existing literature, differentiating 'reproductive' dispersal (i.e. changes in breeding locations) from 'non-reproductive' dispersal, which we define as movements resulting in inter-annual or inter-generational changes in non-breeding locations. Crucially, unlike reproductive dispersal where movement outcomes are naturally propagated between generations, the outcomes of non-reproductive dispersal can be non-heritable even if dispersers survive to reproduce. We simulate a non-social migratory population with a genetically-determined migratory programme to model how heritability of this program influences both migratory connectivity and range shift propensity. When exposed to spatially-uncoupled shifts in habitable ranges (i.e. seasonal climate niches shifting at different rates), long-term persistence of simulated populations required changes in migratory programmes to arise through heritable forms of non-reproductive dispersal (e.g. mutations in migratory gene complexes). By contrast, non-heritable dispersal mechanisms (e.g. weather drift, navigation errors) did not drive long-term shifts in non-breeding ranges, despite being a major component of realised dispersal and migratory connectivity patterns. Migratory connectivity metrics conflate these heritable and non-heritable drivers of non-reproductive dispersal and therefore have limited power in predicting spatial population responses to environmental change. Our models provide a framework for improving our understanding of spatial dynamics in migratory populations and highlight the importance of teasing apart the genetic or cultural mechanisms that drive inter-generational migratory variability in order to evaluate and predict range plasticity in migrants.

description: We have applied the real space quantum renormalization group approach to study the topological quantum phase transition in the one-dimensional chain of a spinless p-wave superconductor. We investigate the behavior of local compressibility and ground-state fidelity of the Kitaev chain. We show that the topological phase transition is signaled by the maximum of local compressibility at the quantum critical point tuned by the chemical potential. Moreover, a sudden drop of the ground-state fidelity and the divergence of fidelity susceptibility at the topological quantum critical point have been used as a proper indicators for the topological quantum phase transition, which signals the appearance of Majorana fermions. We also present the scaling analysis of ground-state fidelity near the critical point that manifests the universal information about the topological phase transition.

When the right conditions are met, an explicit orthonormal basis can be constructed using a particular class of operators. It is natural then to consider how the orthonormal basis changes as we let the basin of attraction vary. We will consider this question for the basins of attraction containing $0$ of the family of polynomials $\mathcal{F} = \{az^{2^{n+2}}-2az^{2^{n+1}}:a\neq0\}$, where $n\in\mathbb{N}$.

Batch Recycle Membrane Test as Alternative to the Rapid, Bench-scale Membrane Test for Evaluation of Nanofiltration of Surface Drinking Waters
Creators: name: Riddick, J. Arthur
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1999

description: Nanofiltration is being widely investigated to remove natural organic matter (NOM), the precursor to disinfection by-products in drinking water. Bench-scale tests are common before more expensive pilot-scale tests of membranes. However, even at bench-scale, a large volume of water will be needed for a complete testing program if the rapid, bench-scale membrane test (RBSMT) is used. A direct comparison of the RBSMT and an alternative, batch recycle membrane test (BaReMT) showed that similar results could be obtained regarding flux decline and NOM rejection. The BaReMT is a more desirable test method because of its ease of operation and smaller sample volume requirement. While a batch volume as small as 4L is acceptable at a recovery of 90%, a larger volume of 15 L is required for recoveries of 80% and less to avoid a foulant limitation. The relationship of recovery and rejection showed that the mass transfer of NOM across the membrane surface was controlled by either diffusion or convection. Several equations were derived to predict the ability of the RBSMT to simulate the performance of a full-scale array configuration. It was shown that at high recoveries (>75%)the RBSMT underestimates the solute concentrations of a full-scale array configuration. Atomic force microscopy and scanning electron microscopy were used to examine the surfaces of several membranes. Microbiological and NOM foulants were found on the surface of the membrane. Finally, it was determined that under conventional pretreatment conditions, the use of nanofiltration (NF) for NOM removal is not feasible for Durham and Fayetteville, NC due to the frequency of cleaning required to maintain an acceptable flux.
Developing Computational Screening Methods for Accelerated Catalyst Discovery
Creators: name: Palizhati, Aini
Publisher: name: Carnegie Mellon University
Year: 2023
Subjects: Computational Chemistry

description: In the last 50 years, increasing human populations have resulted in three times more fossil fuels consumption to meet the demand for energy and fuels. Unfortunately, this has disrupted ecosystems and climate with excessive greenhouse gas emissions. We inevitably need to transition from fossil fuels to renewable energy technologies. Catalyst plays a key role in renewable technology by converting harvested energy to fuels and chemicals. However, today’s catalysts are inadequate for the widespread adoption of renewable technologies. Developing catalysts made from earth-abundant materials and have better performance is more urgent than ever. This thesis is aimed to develop computational methods that search for new catalyst materials more efficient under time and budget constraints. Three areas of contributions in this thesis are: (i) developing open-source workflows and software tools, (ii) determining catalyst properties to screen catalyst more accurately and efficiently, and (iii) closer coupling of experiments and computational methods. We first present our informatics tool Generalized Adsorption Simulator for Python (GASpy) that uses dynamic dependency graphs to share, organize, and schedule adsorption energy calculations to achieve efficient descriptor-based catalysts surface screening. We then show a framework that predicts average surface energy using high-throughput DFT and a machine learning framework. This framework allows us to further down select catalyst surfaces based on their surface stability and the likelihood of their experimental occurrence. We also develop an algorithm that improves upon heuristic strategy and accelerates the search for more accurate descriptors (i.e. the lowestenergy configurations) in complex adsorbate-surface systems with machine learning potentials. Lastly, we implement and benchmark sequential learning agents that allow for the differentiation of data points of different fidelities with a sequential learning framework for closer coupling of theory and experiments.

description: We study asymptotically flat space-times in 3 dimensions for Einstein gravity near future null infinity and show that the boundary is described by Carrollian geometry. This is used to add sources to the BMS gauge corresponding to a non-trivial boundary metric in the sense of Carrollian geometry. We then solve the Einstein equations in a derivative expansion and derive a general set of equations that take the form of Ward identities. Next, it is shown that there is a well-posed variational problem at future null infinity without the need to add any boundary term. By varying the on-shell action with respect to the metric data of the boundary Carrollian geometry we are able to define a boundary energy-momentum tensor at future null infinity. We show that its diffeomorphism Ward identity is compatible with Einstein's equations. There is another Ward identity that states that the energy flux vanishes. It is this fact that is responsible for the enhancement of global symmetries to the full BMS$_3$ algebra when we are dealing with constant boundary sources. Using a notion of generalized conformal boundary Killing vector we can construct all conserved BMS$_3$ currents from the boundary energy-momentum tensor.

description: Any quantum resource theory is based on free states and free operations, i.e., states and operations which can be created and performed at no cost. In the resource theory of coherence free states are diagonal in some fixed basis, and free operations are those which cannot create coherence for some particular experimental realization. Recently, some problems of this approach have been discussed, and new sets of operations have been proposed to resolve these problems. We propose here the framework of genuine quantum coherence. This approach is based on a simple principle: we demand that a genuinely incoherent operation preserves all incoherent states. This framework captures coherence under additional constrains such as energy preservation and all genuinely incoherent operations are incoherent regardless of their particular experimental realization. We also introduce the full class of operations with this property, which we call fully incoherent. We analyze in detail the mathematical structure of these classes and also study possible state transformations. We show that deterministic manipulation is severely limited, even in the asymptotic settings. In particular, this framework does not have a unique golden unit, i.e., there is no single state from which all other states can be created deterministically with the free operations. This suggests that any reasonably powerful resource theory of coherence must contain free operations which can potentially create coherence in some experimental realization.

Development of General Provisions for New National Air Toxics Standards Under the Clean Air Act Amendments of 1990
Creators: name: Dubow, Michele
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: While Congress writes laws that determine national priorities for handling environmental problems, federal agencies write environmental regulations that bridge the gap between Congressional intent and actual implementation of statutes. In developing and codifying regulations, federal bureaucrats make policy decisions and negotiate to resolve conflicts within and outside their agencies. These conflicts usually remain hidden from the public and are not documented. Nevertheless, the content of regulations may be influenced by human and political factors as much as by competent scientific and technical research and policy judgements. Therefore, regulation writers must remain flexible to respond to events as they arise, especially ones that result in deviations from institutionalized systems for regulatory development. The process of developing a single regulation was traced to give insight into the regulatory development process at the U.S. Environmental Protection Agency. Observations, perceptions, and experiences of a participant in the process were documented to show the informal workings of the Agency that outsiders rarely see. Two lessons drawn from this exercise are that the regulatory development process does not follow a "cookbook" formula and having a strategy to advance a regulation can help to ensure its successful development.

title: Assessing the Prevalence and Archival Rate of URIs to Git Hosting Platforms in Scholarly Publications
Creators: name: Escamilla, Emily
Publisher: name: Old Dominion University Libraries
Year: 2023

description: The definition of scholarly content has expanded to include the data and source code that contribute to a publication. While major archiving efforts to preserve conventional scholarly content, typically in PDFs (e.g., LOCKSS, CLOCKSS, Portico), are underway, no analogous effort has yet emerged to preserve the data and code referenced in those PDFs, particularly the scholarly code hosted online on Git Hosting Platforms (GHPs). Similarly, Software Heritage is working to archive public source code, but there is value in archiving the surrounding ephemera that provide important context to the code while maintaining their original URIs. In current implementations, source code and its ephemera are not preserved, which presents a problem for scholarly projects where reproducibility matters. To quantify the scope of this issue, we analyzed the use of GHP URIs in the arXiv and PMC corpora. In total, there were 253,590 URIs to GitHub, SourceForge, Bitbucket, and GitLab repositories across the 2.64 million publications. Authors have increasingly included GHP URIs in scholarly publications and, in 2021, one in five arXiv publications included a GitHub URI. Next, we analyzed the archival coverage of scholarly GHP URIs in Web archives and Software Heritage. Overall, 79.15% of GHP URIs were archived in the Web archives while only 62.06% of GHP URIs were archived in Software Heritage. We used a machine learning classifier to identify other Open Access Data and Software (OADS) URIs outside of the four GHPs previously studied. We found almost 50,000 unique OADS hostnames and more non-GHP OADS URIs than GHP URIs. The prevalence of OADS URIs and vast number of unique hostnames points to the utility of a classifier to identify OADS URIs as opposed to manual enumeration. Lastly, we found a statistically significant relationship between the popularity of a GitHub repository as determined by engagement metrics and archival coverage indicating that less popular repositories less likely to be archived and, thus, more vulnerable to being unrecoverable. The growing use of GHPs in scholarly publications points to an urgent and growing need for dedicated efforts to archive their holdings in order to preserve research code and its scholarly ephemera.
