description: Ultracold neutrons confined in the Earth's gravitational field display quantized energy levels that have been observed for over a decade. In recent resonance spectroscopy experiments [T. Jenke et al., Nature Phys. 7, 468 (2011)], the transition between two such gravitational quantum states was driven by the mechanical oscillation of the plates that confine the neutrons. Here we show that, by applying a sinusoidal modulation with slowly varying frequency (chirp), the neutrons can be brought to higher excited states by climbing the energy levels one by one. The proposed experiment should make it possible to observe the quantum-classical transition that occurs at high neutron energies. Furthermore, it provides a technique to realize superpositions of gravitational quantum states, to be used for precision tests of gravity at short distances.
Weak amenability is stable under graph products

description: Weak amenability of discrete groups was introduced by Haagerup and co-authors in the 1980's. It is an approximation property known to be stable under direct products and free products. In this paper we show that graph products of weakly amenable discrete groups are weakly amenable (with Cowling-Haagerup constant 1). Along the way we construct a wall space associated to the word length structure of a graph product and also give a method for extending completely bounded functions on discrete groups to a completely bounded function on their graph product.

Impact of Microbial-Particle Interaction on Microbial Fate and Transport in Stormwater
Creators: name: Dilts, Mackenzie J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004

description: Storm events and the corresponding runoff often result in a substantial increase in microbial and particulate solids loading to receiving waters. Microbial-particle interactions are important determinants of microbial fate and transport, as microbes associated with particles tend to settle out of waters, while microbes in the free phase may travel much greater distances downstream. These interactions also impact the effectiveness of detention basins for microbial removal from stormwater. The partitioning of several microbial species (fecal coliforms, E.coli, enterococci, Clostridium perfringens spores, and total coliphage) was investigated in urban stormwater runoff. Grab samples were taken under background conditions and during storm events, and samples were also taken throughout one storm event. The fraction of organisms associated with settleable particles was determined by microbial analysis both before and after samples were subjected to a centrifugation process. Centrifugation was shown to remove more than 97% of high density (>2.5g/cm[3]) particles, while retaining the majority of low density (1.05 g/cm[3])particles that were representative of "free phase" microbial organisms. Storm samples were characterized by increased microbial and particle concentrations relative to background conditions. The fraction of organisms removed via centrifugation varied by microbe and between background and storm conditions. The highest average removals were observed in fecal coliforms (28% background; 58% storm) and Cl. perfringens spores (45%)background, 61% storm), whereas total coliphage demonstrated the lowest removals (13% in both background and storm conditions). Particle concentration is consistently high throughout storm events, but peak microbial concentrations tend to vary by microbe. Fecal coliforms tend to be highest as flows are increasing, E.coli concentrations tend to be highest near peak flows, and enterococci and total coliphage concentrations tend to be highest as flows are declining.

description: Multiparty quantum states are useful for a variety of quantum information and computation protocols. We define a multiparty entanglement measure based on local measurements on a multiparty quantum state, and an entanglement measure averaged on the post-measurement ensemble. Using the generalized geometric measure as the measure of multipartite entanglement for the ensemble, we demonstrate, in the case of several well-known classes of multipartite pure states, that the localized multipartite entanglement can exceed the entanglement present in the original state. We also show that measurement over multiple parties may be beneficial in enhancing localizable multipartite entanglement. We point out that localizable generalized geometric measure faithfully signals quantum critical phenomena in well-known quantum spin models even when considerable finite-size effect is present in the system.

description: The increasing popularity of academic social networking sites (ASNSs) requires studies on the usage of ASNSs among scholars and evaluations of the effectiveness of these ASNSs. However, it is unclear whether current ASNSs have fulfilled their design goal, as scholars' actual online interactions on these platforms remain unexplored. To fill the gap, this article presents a study based on data collected from ResearchGate. Adopting a mixed-method design by conducting qualitative content analysis and statistical analysis on 1,128 posts collected from ResearchGate Q&A, we examine how scholars exchange information and resources, and how their practices vary across three distinct disciplines: library and information services, history of art, and astrophysics. Our results show that the effect of a questioner's intention (i.e., seeking information or discussion) is greater than disciplinary factors in some circumstances. Across the three disciplines, responses to questions provide various resources, including experts' contact details, citations, links to Wikipedia, images, and so on. We further discuss several implications of the understanding of scholarly information exchange and the design of better academic social networking interfaces, which should stimulate scholarly interactions by minimizing confusion, improving the clarity of questions, and promoting scholarly content management.

A Comparison of Self-Reported and Publicly Reported Environmental Regulatory Information
Creators: name: Kron, Rachel Beth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1999

description: A comparative data analysis of regulatory status and violation information reported to an academic study and mandated reporting data reported to EPA databases was conducted for 13 businesses and manufacturing facilities. The data compared included air, hazardous waste, and water regulatory statuses and violations to air, hazardous waste, and water regulations for the years 1995, 1996, and 1997. The results conclude that the regulatory status data of these two datasets were similar but the violation data did vary considerably. Of the 34 violations in the IRD for these 13 facilities, 3 violations matched information in the mandated reporting data. The problems of environmental reporting such as identification of sources, route of reporting, and lack of uniformity of reporting are some hypotheses suggesting why these two datasets diverge. This report suggests the greater implications of these problems and recommendations on how to obtain a more complete mandated reporting dataset.

Superconvergence of Immersed Finite Element Methods for Interface Problems

Publisher: name: arXiv
Year: 2015
Subjects: subject: Numerical Analysis (math.NA)

description: In this article, we study superconvergence properties of immersed finite element methods for the one dimensional elliptic interface problem. Due to low global regularity of the solution, classical superconvergence phenomenon for finite element methods disappears unless the discontinuity of the coefficient is resolved by partition. We show that immersed finite element solutions inherit all desired superconvergence properties from standard finite element methods without requiring the mesh to be aligned with the interface. In particular, on interface elements, superconvergence occurs at roots of generalized orthogonal polynomials that satisfy both orthogonality and interface jump conditions.

description: This paper investigates the asymptotic behaviour of solutions to certain infinite systems of ordinary differential equations. In particular, we use results from ergodic theory and the asymptotic theory of $C_0$-semigroups to obtain a characterisation, in terms of convergence of certain Cesàro averages, of those initial values which lead to convergent solutions. Moreover, we obtain estimates on the rate of convergence for solutions whose initial values satisfy a stronger ergodic condition. These results rely on a detailed spectral analysis of the operator describing the system, which is made possible by certain structural assumptions on the operator. The resulting class of systems is sufficiently broad to cover a number of important applications, including in particular both the so-called robot rendezvous problem and an important class of platoon systems arising in control theory. Our method leads to new results in both cases.

The Effect of Work Environment on the Breathing-Zone Concentrations of 1,6-Hexamethylen Diisocyanate Monomer and its Oligomers in Automotive Refinishing Industry
Creators: name: Kim, Wook
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Diisocyanates are common components in spray-paint hardeners used in automotive refinishing industry and are major cause of occupational asthma. The contribution of work-related factors to the breathing-zone concentrations of 1,6-hexamethylene diisocyanate (HDI) monomer and its oligomers uretidone, biuret, and isocyanurate was investigated in 25 spray-painters in 19 auto-repair shops. The most important factor contributing to the HDI monomer and oligomer exposures was the concentrations of these compounds in the paint (for all p <0.05). Paint time (p = 0.017) and the amount of paint used (p = 0.020) also significantly increased HDI monomer exposure. HDI isocyanurate exposure was only affected by its paint concentration (p = 0.003). Because HDI isocyanurate exposure constitutes the largest amount of spray painters' exposure for this worker population (?700-fold greater than HDI monomer), selection of paints containing less isocyanurate could significantly reduce spray-painters exposure.

description: We report measurements of the upper critical field $H_{\mathrm{c2}}$ as functions of temperature $T$, polar angle $θ$ (of the field direction with respect to the crystallographic $c$ axis), and azimuthal angle $ϕ$ (of the field direction relative to the $a$ axis within the $ab$ plane) for the Cr-based superconductor K$_{2}$Cr$_{3}$As$_{3}$ with a quasi-one-dimensional and non-centrosymmetric crystal structure. We confirm that the anisotropy in $H_{\mathrm{c2}}(T)$ becomes inverse with decreasing temperature. At low temperatures, $H_{\mathrm{c2}}(θ)$ data are featured by two maxima at $θ$ = 0 ($\mathbf{H}\parallel c$) and $π/2$ ($\mathbf{H}\bot c$), which can be quantitatively understood only if uniaxial effective-mass anisotropy and absence of Pauli paramagnetic effect for $\mathbf{H}\bot c$ are taken simultaneously into consideration. The in-plane $H_{\mathrm{c2}}(ϕ)$ profile shows a unique threefold modulation especially at low temperatures. Overall, the characteristic of the $H_{\mathrm{c2}}(θ, ϕ, T)$ data mostly resemble those of the heavy-fermion superconductor UPt$_3$, and we argue in favor of a dominant spin-triplet superconductivity with odd parity in K$_{2}$Cr$_{3}$As$_{3}$.

How does mobility affect the connectivity of interference-limited ad-hoc networks?

Subjects: subject: Networking and Internet Architecture (cs.NI)

description: One limiting factor to the performance of mobile ad-hoc networks is the amount of interference that is experienced by each node. In this paper we use the Random Waypoint Mobility Model (RWPM) to represent such a network of mobile devices, and show that the connectivity of a receiver at different parts of the network domain varies significantly. This is a result of a large portion of the nodes in the RWPM being located near the centre of the domain resulting in increased levels of interference between neighbouring devices. A non-trivial trade-off therefore exists between the spatial intensity of interfering signals and non-interfering (useful) ones. Using tools from stochastic geometry, we derive closed form expressions for the spatial distribution of nodes in a rectangle and the connection probability for an interference limited network indicating the impact an inhomogeneous distribution of nodes has on a network's performance. Our novel results can be used to analyse this trade-off and optimize network performance.

Year: 2015

description: We consider a family of quantum channels characterized by the fact that certain (in general nonorthogonal) Pure states at the channel entrance are mapped to (tensor) Products of Pure states (PPP, hence "pcubed") at the complementary outputs (the main output and the "environment") of the channel. The pcubed construction, a reformulation of the twisted-diagonal procedure by M. M Wolf and D. Perez-Garcia, [Phys. Rev. A 75, 012303 (2007)], can be used to produce a large class of degradable quantum channels; degradable channels are of interest because their quantum capacities are easy to calculate. Several known types of degradable channels are either pcubed channels, or subchannels (employing a subspace of the channel entrance), or continuous limits of pcubed channels. The pcubed construction also yields channels which are neither degradable nor antidegradable (i.e., the complement of a degradable channel); a particular example of a qutrit channel of this type is studied in some detail. Determining whether a pcubed channel is degradable or antidegradable or neither is quite straightforward given the pure input and output states that characterize the channel. Conjugate degradable pcubed channels are always degradable.

description: Metallic alloys are important materials in engineering for their versatile properties. With the development of computational power, molecular simulation plays an increasingly important role to study the properties of metallic alloys. Molecular simulation is used to calculate the properties that are hard or expensive to be measured experimentally. Traditional molecular simulation relies on density functional theory (DFT) or empirical potentials to calculate the energies and forces during the simulations. DFT provides higher accuracy, but it is more time-consuming. Empirical potentials are much faster but they are not as accurate as DFT. Recently, machine learning (ML) potentials have become attractive because they are potentially both accurate and fast. When trained with sufficient data, machine learning potentials could be as accurate as DFT. Also, because machine learned potentials are essentially regression models, their inferences could be as fast as empirical potentials. With the help of machine learning models, simulations for large molecular systems can be accurately finished with a reasonable computational cost. In this dissertation, we combined ML methods, DFT, and Monte Carlo (MC) simulations to study the surface segregation of the CuPdAu alloy under vacuum conditions. We built a neural network (NN) model to accurately approximate the DFT potential energies during the MC simulations which were used to estimate the surface compositions of the CuPdAu alloy with various bulk compositions. A range of factors that might contribute to surface segregation was investigated, such as surface relaxation, vibrational contribution, and orientation dependence. Next, we developed a NN ensemble-based active learning method to accelerate the geometry optimization process, which enabled us to obtain the ground-state structures in a faster way. We used a NN-ensemble approach to provide the uncertainty estimation of the NN prediction during the molecular simulation, such that we were able to replace the DFT calculation using the NN model appropriately during the geometry optimization process. After that, the surface segregation and aggregation phenomenon was investigated using semi-grand canonical Monte Carlo simulation with the help of ML surrogate models for the bulk, slab potential energies, and the pseudo-adsorption energies. Then, we illustrated using automatic differentiation to evaluate the degree of rate control (DRC). Automatic differentiation provided higher accuracy and faster computation of the DRC. Lastly, we developed an efficient method to search for similar molecular structures in a large database. The search method was based on the approximate nearest neighbor search and machine learning embedding.

description: This working paper presents an analysis plan for data collected from cross-country discrete choice experiments (DCEs) of tobacco product use. We will use the evidence from the DCEs for economic policy analysis of tobacco product regulations. We will use applied econometric methods to predict the effects of alternative tobacco regulations on the use of cigarettes, use of e-cigarettes, and tobacco cessation. We will also use the results to conduct applied welfare economic analysis of the costs and benefits of tobacco regulations. The overarching goal of our research is to contribute to evidence-based tobacco regulatory policy-making.

description: Grounding (i.e. localizing) arbitrary, free-form textual phrases in visual content is a challenging problem with many applications for human-computer interaction and image-text reference resolution. Few datasets provide the ground truth spatial localization of phrases, thus it is desirable to learn from data with no or little grounding supervision. We propose a novel approach which learns grounding by reconstructing a given phrase using an attention mechanism, which can be either latent or optimized directly. During training our approach encodes the phrase using a recurrent network language model and then learns to attend to the relevant image region in order to reconstruct the input phrase. At test time, the correct attention, i.e., the grounding, is evaluated. If grounding supervision is available it can be directly applied via a loss over the attention mechanism. We demonstrate the effectiveness of our approach on the Flickr 30k Entities and ReferItGame datasets with different levels of supervision, ranging from no supervision over partial supervision to full supervision. Our supervised variant improves by a large margin over the state-of-the-art on both datasets.

Dispersion and Electrospray Aerosol Generation of Engineered Nano-TiO2: Preliminary Investigation of an Alternative Method of in vitro Exposure
Creators: name: Krug, Jonathan D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: A stable dispersion of Ti02 by adjustment of solution pH above the isoelectric point of TiO2 was created. Once estabHshed, the TiO2 dispersion was aerosolized by a TSI Model 3480 Electrospray Aerosol Generator. Measurements were made of TiO2 agglomerate size in solution by Dynamic Light Scattering (DLS) and Transmission Electron Microscopy (TEM) and post electrospray by TEM. A custom built biological electrostatic precipitator was used to deposit the Ti02 aerosol onto TEM grids. Baseline collection efficiency measurements were obtained for the biological electrostatic precipitator in terms of number efficiency and deposition pattern into cell culture wells through the use of fluorescein dye. The 32 nm Ti02 was found to have minimum agglomerate diameter of 185.9 nm at pH10.2 with zeta potential of 47.3 mV. Minimum diameter post electrospray was found to be 68.3 nm by TEM. The electrostatic precipitator was found to have plate area deposition by mass of 36.68% based on incoming aerosol.

description: This paper develops a comparative framework for the design of actuated inertial appendages for planar, aerial reorientation. We define the Inertial Reorientation template, the simplest model of this behavior, and leverage its linear dynamics to reveal the design constraints linking a task with the body designs capable of completing it. As practicable inertial appendage designs lead to morphology that is generally more complex, we advance a notion of "anchoring" whereby a judicious choice of physical design in concert with an appropriate control policy yields a system whose closed loop dynamics are sufficiently captured by the template as to permit all further design to take place in its far simpler parameter space. This approach is effective and accurate over the diverse design spaces afforded by existing platforms, enabling performance comparison through the shared task space. We analyze examples from the literature and find advantages to each body type, but conclude that tails provide the highest potential performance for reasonable designs. Thus motivated, we build a physical example by retrofitting a tail to a RHex robot and present empirical evidence of its efficacy.

description: Crude oil is one of the largest and most complex contributors of organic pollution in marine environments. The fact that our oceans are not covered in oil is, in part, due to the activities of hydrocarbon-degrading bacteria. Although relationships between phytoplankton and bacteria have been studied extensively, the ability of phytoplankton-associated bacteria to degrade components of crude oil has not been well-studied. Recent research has revealed an association between marine phytoplankton and bacteria that can degrade polycylic aromatic hydrocarbons (PAHs), a component of major concern in crude oil. This work expands on this research by investigating the effect of crude oil on the bacterial community associated with the marine diatom, Skeletonema costatum. Laboratory microcosms of S. costatum in seawater medium were incubated in the presence or absence of oil over a 64-day period. Growth of S. costatum was inhibited after the addition of oil, while total bacterial counts increased relative to the oil-untreated control. Quantitative PCR and pyrosequence analysis revealed members of the Marinobacter genus, which are known hydrocarbon-degraders, had significantly increased in abundance compared to the oil-untreated control. Notably, a significant increase in the abundance of Methylophaga species within the γ-Proteobacteria class was observed three days after the oil was added, representing over 80% of the total bacterial community in oil-contaminated microcosms. Despite substantial changes in the bacterial communities in contaminated microcosms, degradation of PAHs and alkane hydrocarbons was not found to be significant compared to killed controls. This result is likely due to low yields of bacteria on the growth substrates present after addition of oil. Overall, the results of this work have revealed new information on the identity and dynamics of bacteria associated with S. costatum during exposure to crude oil. These findings have taken us a step forward to better understanding the role that algal-bacterial associations might play in bioremediation processes at sea after an oil pollution event, for which further research on the relationship between phytoplankton and oil-degrading bacteria is needed.

description: Deep Neural Networks such as Recurrent Neural Networks and Transformer models are widely adopted for their superior performance in many natural language processing (NLP) applications, but they remain largely black-box which can lead to unwanted bias and unrobust behaviors. To discover, diagnose and evaluate these issues, it is essential to make NLP systems accountable, reliable and most importantly, explainable. Explainability tools and methods can be leveraged by NLP practitioners to better understand how model make certain predictions, if the models are conceptually sound, and if the predictions are justified. In this dissertation, we propose new explainability frameworks for NLP models, and show how those frameworks can be used to understand and evaluate NLP models beyond their accuracy metrics. Inspired by prior explainability approaches, our methods are designed to be distinctively suitable for textual data and NLP model architectures. Our proposed methods can help understand exactly how a linguistic concept is represented in a model by answering two conceptual soundness questions: (1) how does important linguistic information flow from input words to output predictions? (2) how is the relative order of words/phrases encoded? We experiment with both recurrent and Transformer architectures across a variety of NLP tasks and show how our methods precisely and faithfully explain and evaluate the inner workings and order-sensitivity of NLP models. Furthermore, we exemplify generated explanations in key NLP tasks depicting how various linguistic concepts are represented, whether those representations are compatible with the underlying grammatical and linguistic rules, and how deviation from those rules manifests into model weaknesses and conceptual unsoundness.

Non-commuting two-local Hamiltonians for quantum error suppression

description: Physical constraints make it challenging to implement and control many-body interactions. For this reason, designing quantum information processes with Hamiltonians consisting of only one- and two-local terms is a worthwhile challenge. Enabling error suppression with two-local Hamiltonians is particularly challenging. A no-go theorem of Marvian and Lidar [Physical Review Letters 113(26), 260504 (2014)] demonstrates that, even allowing particles with high Hilbert-space dimension, it is impossible to protect quantum information from single-site errors by encoding in the ground subspace of any Hamiltonian containing only commuting two-local terms. Here, we get around this no-go result by encoding in the ground subspace of a Hamiltonian consisting of non-commuting two-local terms arising from the gauge operators of a subsystem code. Specifically, we show how to protect stored quantum information against single-qubit errors using a Hamiltonian consisting of sums of the gauge generators from Bacon-Shor codes [Physical Review A 73(1), 012340 (2006)] and generalized-Bacon-Shor code [Physical Review A 83(1), 012320 (2011)]. Our results imply that non-commuting two-local Hamiltonians have more error-suppressing power than commuting two-local Hamiltonians. While far from providing full fault tolerance, this approach improves the robustness achievable in near-term implementable quantum storage and adiabatic quantum computations, reducing the number of higher-order terms required to encode commonly used adiabatic Hamiltonians such as the Ising Hamiltonians common in adiabatic quantum optimization and quantum annealing.

description: We present and analyse a micro-macro acceleration method for the Monte Carlo simulation of stochastic differential equations with separation between the (fast) time-scale of individual trajectories and the (slow) time-scale of the macroscopic function of interest. The algorithm combines short bursts of path simulations with extrapolation of a number of macroscopic state variables forward in time. The new microscopic state, consistent with the extrapolated variables, is obtained by a matching operator that minimises the perturbation caused by the extrapolation. We provide a proof of the convergence of this method, in the absence of statistical error, and we analyse various strategies for matching, as an operator on probability measures. Finally, we present numerical experiments that illustrate the effects of the different approximations on the resulting error in macroscopic predictions.

description: The authors present empirical distributions for the halting time (measured by the number of iterations to reach a given accuracy) of optimization algorithms applied to two random systems: spin glasses and deep learning. Given an algorithm, which we take to be both the optimization routine and the form of the random landscape, the fluctuations of the halting time follow a distribution that, after centering and scaling, remains unchanged even when the distribution on the landscape is changed. We observe two qualitative classes: A Gumbel-like distribution that appears in Google searches, human decision times, the QR eigenvalue algorithm and spin glasses, and a Gaussian-like distribution that appears in conjugate gradient method, deep network with MNIST input data and deep network with random input data. This empirical evidence suggests presence of a class of distributions for which the halting time is independent of the underlying distribution under some conditions.
