Subjects: subject: Atomic Physics (physics.atom-ph)
subject: FOS: Physical sciences

description: It is shown that homogeneous line-broadening in a diffuse cold atom cloud is proportional to the resonant optical depth of the cloud. Further, it is demonstrated how the strong directionality of the coherent interactions causes the cloud's spectra to depend strongly on its shape, even when the cloud is held at constant densities. These two numerical observations can be predicted analytically by extending the single photon wave-function model. Lastly, elongating a cloud along the line of laser propagation causes the excitation probability distribution to deviate from the exponential decay predicted by the Beer-Lambert law to the extent where the atoms in the back of the cloud are more excited than the atoms in the front. These calculations are conducted at low densities relevant to recent experiments.

description: We analyze a compression scheme for large data sets that randomly keeps a small percentage of the components of each data sample. The benefit is that the output is a sparse matrix and therefore subsequent processing, such as PCA or K-means, is significantly faster, especially in a distributed-data setting. Furthermore, the sampling is single-pass and applicable to streaming data. The sampling mechanism is a variant of previous methods proposed in the literature combined with a randomized preconditioning to smooth the data. We provide guarantees for PCA in terms of the covariance matrix, and guarantees for K-means in terms of the error in the center estimators at a given step. We present numerical evidence to show both that our bounds are nearly tight and that our algorithms provide a real benefit when applied to standard test data sets, as well as providing certain benefits over related sampling approaches.

description: Background: Nuts are nutrient-dense foods, rich in unsaturated fatty acids, proteins, fiber, minerals, antioxidants and other phytochemicals. These oilseeds are part of the Mediterranean diet and are eaten as snacks, desserts or part of a meal. Dietary compounds such as nuts can modulate the secretion of enterohormones related to appetite and satiety. In the context of the global obesity epidemic, understanding the mechanisms that control human appetite is crucial, since obesity is a state of energy dysregulation characterized by decreased hormonal appetite signaling and excess adiposity, a risk factor for cardiovascular disease, diabetes, musculoskeletal disorders and some cancers. Studies have shown that consuming nuts can help control weight by reducing appetite and decreasing fat absorption. Thus, our aim is to identify the effects of nuts on receptors and hormones that regulate appetite in overweight and obese adults. Methods: We will carry out a scope review following the Joanna Briggs Institute manual, for the selection, extraction and presentation of data. Based on the PCC acronym (P – population, C – concept and C – context) we elaborate the following question: What are the effects of nuts on receptors and hormones that regulate appetite in overweight and obese adults? Thus, we will map the key concepts and examine the breadth of existing evidence available on the topic. We will detail the flow of research, data extraction and evidence presentation, through the review process flowchart and apply the Prisma ScR extension checklist. Our systematic search will be conducted in November 2021 and will only include clinical trials from five electronic databases: MEDLINE/PubMed, Embase, Web of Science, Cochrane Library and Scopus. The data will be extracted and registered in a pre-defined data form and will be presented in a tabular form, accompanied by a descriptive summary. Population: Overweight and obese adults Concept: Effect of nut consumption on appetite-regulating hormones and receptors Context: Literature data on the action mechanisms of nut compounds that participate in appetite-regulation.
Development and Applications of an Analytical Method for Measurements of Hydroxyacetone and Glycolaldehyde in Air
Creators: name: Liu, Fang
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: An analytical method for measurement of glycolaldehyde and hydroxyacetone has been developed. This method includes derivatization of hydroxylated carbonyl by 2,4-dintrophenylhydrazine (DNPH) and subsequent analysis of the derivatives using high performance liquid chromatography (HPLC). This method has been applied on the smog chamber experiments with satisfactory results. Glycolaldehyde and hydroxyacetone can be detected at 0.025ug/ml and 0.085ug/ml level, or at 10ppb and 29ppb in air with a 1L standard air sample volume using this analytical system. In this study, a new scheme for reactions of hydroxylated carbonyls with 2,4-DNPH has been proposed based on the interpretation of mass spectra of these derivatives. Based on this reaction scheme and experimental data, the structures of DNPH derivatives of dicarbonyls and hydroxylated carbonyls have been found identical, but the reaction rates for dicarbonyls and hydroxylated carbonyl with DNPH are varied under different acidic conditions. According to this discovery, a procedure has been developed for the measurement of both dicarbonyls (glyoxal and methyl-glyoxal) and hydroxylated carbonyls (glycolaldehyde and hydroxyacetone). The problem of interferences (if both dicarbonyl andhydroxylated carbonyl exist in the same system), therefore, can be solved.

description: Motivated in part by the study of the stable homology of automorphism groups of free groups, we consider cohomological calculations in the category $\mathcal{F}(\textbf{gr})$ of functors from finitely generated free groups to abelian groups.In particular, we compute the groups $Ext^*\_{\mathcal{F}(\textbf{gr})}(T^n \circ \mathfrak{a}, T^m \circ \mathfrak{a})$ where $\mathfrak{a}$ is the abelianization functor and $T^n$ is the n-th tensor power functor for abelian groups. These groups are shown to be non-zero if and only if $*=m-n \geq 0$ and $Ext^{m-n}\_{\mathcal{F}(\textbf{gr})}(T^n \circ \mathfrak{a}, T^m \circ \mathfrak{a})=\mathbb{Z}[Surj(m,n)]$ where $Surj(m,n)$ is the set of surjections from a set having $m$ elements to a set having $n$ elements. We make explicit the action of symmetric groups on these groups and the Yoneda and external products. We deduce from these computations those of rational Ext-groups for functors of the form $F \circ \mathfrak{a}$ where $F$ is a symmetric or an exterior power functor. Combining these computations with a recent result of Djament we obtain explicit computations of stable homology of automorphism groups of free groups with coefficients given by particular contravariant functors.

A Rat Model of Heart Failure Induced by Isoproterenol and/or High Salt Diet to Examine the Effects of Particulate Matter Inhalation
Creators: name: Carll, Alex P.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Ambient particulate matter (PM) exposure is linked to cardiovascular complications and death— especially for individuals with preexisting heart failure. A model of heart failure was developed in Spontaneously Hypertensive Heart Failure (SHHF) rats. Four-week isoproterenol infusion (ISO;2.5mg/kg/day) induced mid- treatment tachycardia and hypotension and post-treatment heartrate (HR), blood pressure, pulse pressure (PP) and contractility decrements suggesting heart failure. ISO induced cardiac hypertrophy and fibrotic cardiomyopathy. PP, HR, and HR variability (HRV) alterations post-ISO indicated parasympathetic dominance and sympathetic desensitization. Cardiac insufficiency dissipated before PM inhalation at 3 weeks post- ISO. After saline but not ISO infusion, PM slightly decreased HRV, possibly because of adrenergic responsiveness differences. ISO potentiated PM-induced pulmonary injury and atrioventricular conduction interference. The ISO regimen was repeated in non- telemetered SHHFs. At 2 weeks, rats received high-salt diets for 6 weeks. The data suggest co-exposure to ISO+8% salt more effectively elicits a heart failure-like state.

description: Microorganisms bind to the glycans attached to proteins, thus the goal of this study was to investigate the role of glycans in the adherence of specific microbial strains linked to the oral microbiome or oral infections. This was investigated by microbial adhesion assay on polyvinylidene fluoride (PVDF) membrane plate with saliva proteins containing N-linked and O-linked glycans immobilized in the wells. Common microorganisms in the oral cavity were selected. The results will help in the understanding of microorganisms binding profiles to the salivary glycoproteins. The effect of saliva from people having different ABO-blood groups on microbial binding was investigated. The potential use of polysaccharides extracted from seaweeds to bind to the microbes to reproduce the role of salivary glycoproteins in populating the oral microbiome was also studied. The seaweed extracts were produced by the industrial partner Venus Shell Systems®, through a series of extraction procedures. The microbes were binding differently to ABO saliva types and responded differently after preincubation with seaweed extracts. The future scope of this study will be to find the best seaweed extract that can mimic the role of saliva in the binding of the beneficial microbiome whilst removing pathogens from populating the dry mouth of cancer patients undergoing chemotherapy.

description: The scattering equations, originally introduced by Fairlie and Roberts in 1972 and more recently shown by Cachazo, He and Yuan to provide a kinematic basis for describing tree amplitudes for massless particles in arbitrary space-time dimension, have been reformulated in polynomial form. The scattering equations for N particles are equivalent to N-3 polynomial equations h_m=0, m=1,...,N-3, in N-3 variables, where h_m has degree m and is linear in the individual variables. Facilitated by this linearity, elimination theory is used to construct a single variable polynomial equation of degree (N-3)! determining the solutions. Δ_N is the sparse resultant of the system of polynomial scattering equations and it can be identified as the hyperdeterminant of a multidimensional matrix of border format within the terminology of Gel'fand, Kapranov and Zelevinsky. Macaulay's Unmixedness Theorem is used to show that the polynomials of the scattering equations constitute a regular sequence, enabling the Hilbert series of the variety determined by the scattering equations to be calculated, independently showing that they have (N-3)! solutions.

Characterization of Two Novel Proteobacteria Isolated from Contaminated Soil and Capable of Degrading Aromatic Compounds
Creators: name: Corteselli, Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The previously uncultivated bacterial strains Ca6T and TR3.2T were isolated from an aerobic bioreactor treating polycyclic aromatic hydrocarbon- (PAH-) contaminated soils collected from former manufactured gas plants in North Carolina. Stable isotope probing (SIP) of one of those soils had previously identified several undescribed, phylogenetically distinct groups of high-molecular weight (HMW) PAH-degrading bacteria, including "pyrene group 1" (PG1) and "pyrene group 2" (PG2), of which Ca6T and TR3.2T are members, respectively. Strain Ca6T is a rod-shaped Betaproteobacterium belonging to the Rhodocyclaceae family, and strain TR3.2T could only be classified as a member of the class Gammaproteobacteria. Of the organic compounds tested, both strains grew on a very limited number of common substrates. However, Ca6T was capable of growth on the PAHs pyrene and phenanthrene as sole sources of carbon, weak growth on benz[a]anthracene, and could transform anthracene and fluorene. TR3.2T utilized several HMW PAHs as sole sources of carbon, including benz[a]anthracene and pyrene, as well as anthracene, fluorene, and phenanthrene. Neither strain possessed any close, cultivated relatives based on 16S rRNA gene sequence analysis. Based on this evidence, novel genera and species are proposed for each strain. The presence of highly similar environmental gene sequences to those in Ca6T and TR3.2T at other contaminated sites worldwide suggests these organisms may be important and ubiquitous degraders of hazardous aromatic compounds.
The physics of antineutrinos in DUNE and determination of octant and $δ_{CP}$

description: The octant of $θ_{23}$ and $δ_{CP}$ are the two major unknowns in neutrino oscillation physics. The precise determination of octant and $δ_{CP}$ is interlinked through the octant-$δ_{CP}$ degeneracy. In this paper we study the proficiency of the DUNE experiment to determine these parameters, in particular, the role played by the antineutrinos, the broadband nature of the beam and the matter effect. For $P_{μe}$ and $P_{\barμ \bar{e}}$ the octant-$δ_{CP}$ degeneracy occurs at different values of $δ_{CP}$, combination of neutrino and antineutrino runs help to resolve this. However, in regions where neutrinos do not have octant degeneracy adding antineutrino data is expected to decrease the sensitivity because of the degeneracy and reduced statistics. However we find that in case of DUNE baseline, the antineutrino runs help even in parameter space where the antineutrino probabilities suffer from degeneracies. We explore this point in detail and point out that this happens because of the (i) broad-band nature of the beam so that even if there is degeneracy at a particular energy bin, over the whole spectrum the degeneracy may not be there; (ii) the enhanced matter effect due to the comparatively longer baseline which creates an increased tension between the neutrino and the antineutrino probabilities which raises the overall $χ^2$ in case of combined runs. This feature is more prominent for IH since the antineutrino probabilities in this case are much higher than the neutrino probabilities due to matter effects. The main role of antineutrinos in enhancing CP sensitivity is their ability to remove the octant-$δ_{CP}$ degeneracy. However even if one assumes octant to be known the addition of antineutrinos can give enhanced CP sensitivity in some parameter regions due to the tension between the neutrino and antineutrino $χ^2$s.

Toxicological Effects of Irradiated Ambient Particulate Matter on A549 Human Lung Cell Line
Creators: name: Hunt, Boyce P., Jr.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: Epidemiological studies have demonstrated associations between ambient air particulate matter (PM) and respiratory disease. This study focused on exposure of ambient air particulate matter to ultraviolet light and subsequent interactions between irradiated particles and human lung cells using the A549 human lung cell line model. ICP analysis showed increases in soluble iron levels following ultraviolet light exposure. Toxicity was assessed 1, 6, and 24 hours after exposure of A549 cells to irradiated or non-irradiated particles by measuring cellular proliferation (MTT assay) and release of LDH and interleukin-6 (IL-6). LDH levels were significantly increased 24 hours after exposure of cells to irradiated particles in comparison to cells exposed to non-irradiated particles. Significant associations were also seen between increased MTT-reducing activity in both irradiated and non-irradiated particles at all doses, and at all time points compared to controls. Twenty-four hours after exposure, IL-6 levels were significantly increased only after exposure to the highest dose of non-irradiated particles. These findings indicate possible correlations between ambient particulate irradiation and increased particle constituent bioavailability, resulting in increased cellular toxicity.

description: We theoretically study the stability of three dimensional Dirac semimetals against short-range electron-electron interaction and quenched time-reversal symmetric disorder (but excluding mass disorder). First we focus on the clean interacting and the noninteracting dirty Dirac semimetal separately, and show that they support two distinct quantum critical points. Using renormalization group techniques, we find that while interaction driven quantum critical points are \emph{Gaussian} (mean-field) in nature, describing quantum phase transitions into various broken symmetry phases, the ones controlled by disorder are \emph{non-Gaussian}, capturing the transition to a metallic phase. We classify such diffusive quantum critical points based on the transformation of disorder vertices under a \emph{continuous} chiral rotation. Our wek coupling renormalization group analysis suggests that two distinct quantum critical points are stable in an interacting dirty Dirac semimetal (with chiral symmetric randomness), and a multicritical point (at finite interaction and disorder) results from their interplay. By contrast, the chiral symmetry breaking disorder driven critical point is unstable against weak interactions. Effects of weak disorder on the ordering tendencies in Dirac semimetal are analyzed. The clean interacting critical points, however, satisfy the \emph{Harris criterion}, and are therefore expected to be unstable against bond disorder. Although our weak coupling analysis is inadequate to establish the ultimate stability of these fixed points in the strong coupling regime (when both interaction and disorder are strong), they can still govern crossover behaviors in Dirac semimetals over a large length scale, when either interaction or randomness is sufficiently weak.

Reducing Inhibition in the Quantitative Real-Time PCR Detection of Adenovirus, Norovirus, and MS-2 in Recreational Waters
Creators: name: Thie, Lauren J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Quantitative real-time PCR (qRT-PCR) has been previously used to detect adenovirus (Ads) and norovirus (Nvs) in recreational waters. However, qRT-PCR detection may be limited by interference from inhibitory substances found in recreation waters. In previous work, viruses in Avalon and Doheny Beach water samples were concentrated by cartridge filtration and PEG precipitation, and high inhibition was found in the samples when using qRT-PCR for the detection of Ads and Nvs. Therefore, different approaches were evaluated for the removal or blocking of inhibitory compounds that affect qRT-PCR. Avalon and Doheny concentrates were spiked with known amounts of Ads 41, Nvs GII, and the coliphage MS-2, and spiked deionized water was used as a control. Modifications included gel chromatography with columns of Sephadex G-200/Chelex 100, different nucleic acid extraction volumes, organic solvent extraction, precipitation with alcohols, and the addition of polyvinylpyrrolidone (PVP), glycerol, and bovine serum albumin (BSA) to the qRT-PCR mix. Inhibition was measured by comparing average qRT-PCR results for sample waters to the average qRT-PCR result for deionized water (ΔCt). For Doheny Beach, Sephadex G-200 chromatography followed by chloroform extraction of 300 μL sample volume for Ads (Δ0.03, p=0.8963), guanidinium thiocyanate (GuSCN) extraction of 50 μL sample volume for Nvs(ΔO.10), and chloroform extraction of 300 μL sample volume for MS-2 (Δ5.52) were most effective. For Avalon Beach, Sephadex G-200 and Chelex 100 chromatography with GuSCN extraction of 300 μL for Ads (Δ1.94), GuSCN extraction of 50 μL volumes for Nvs (Δ2.47), and Sephadex G-200 chromatography followed by chloroform extraction of 300 μL volumes for MS-2 (Δ3.59) were the most effective methods. Avalon Beach waters showed more inhibition than Doheny Beach waters. Analysis of organic content in concentrated samples revealed a high concentration of fulvic acids in Avalon Beach water and a high concentration of humic acids in Doheny Beach. These chemical findings corroborate the greater difficulty in removing inhibitors from Avalon Beach waters, as fulvic acids are more soluble in seawater, and thus less easily removed from samples. The results suggest that qRT-PCR methods for Ads and Nvs detection can be optimized for detection of target viruses to overcome inhibitory substances specific to water sample locations.

description: In typical discrete-time quantum walk algorithms, one measures the position of the walker while ignoring its internal spin/coin state. Rather than neglecting the information in this internal state, we show that additionally measuring it doubles the success probability of many quantum spatial search algorithms. For example, this allows Grover's unstructured search problem to be solved with certainty, rather than with probability 1/2 if only the walker's position is measured, so the additional measurement yields a search algorithm that is twice as fast as without it, on average. Thus the internal state of discrete-time quantum walks holds valuable information that can be utilized to improve algorithms. Furthermore, we determine conditions for which spatial search problems on regular graphs are amenable to this doubling of the success probability, and this involves diagrammatically analyzing search using degenerate perturbation theory and deriving a useful formula for how the quantum walk acts in its reduced subspace.

A Structural Characterization of an Aquatic Fulvic Acid
Creators: name: MacNeela, John Paul
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1988

description: The structural characterization of an aquatic fulvic acid was attempted. Several approaches toward obtaining information concerning the structure of a fulvic acid were taken. These included analysis of the products from a mild oxidative degradation, elemental analysis, and spectroscopic analysis of the undegraded fulvic acid. The oxidative degradation method employed for this research was an alkaline cupric oxide oxidation. Validation of this method with model compounds was accomplished prior to the oxidation of the fulvic acid by this technique. The products obtained from this procedure were analyzed by gas chromatography and combined gas chromatography/mass spectrometry. Spectroscopic techniques employed for the purposes of analyzing the structure of the undegraded fulvic acid include infrared spectroscopy and proton and solid state (13)C nuclear magnetic resonance spectroscopies. Additionally, the effects of the oxidative conditions employed for the alkaline cupric oxide oxidation on selected compounds was investigated. Analysis of the resulting products was performed in the same manner as that for the oxidatively degraded fulvic acid.

description: The growing sluggishness of glass-forming liquids is thought to be accompanied by growing structural order. The nature of such order, however, remains hotly debated. A decade ago, point-to-set (PTS) correlation lengths were proposed as measures of amorphous order in glass formers, but recent results raise doubts as to their generality. Here, we extend the definition of PTS correlations to agnostically capture any type of growing order in liquids, be it local or amorphous. This advance enables the formulation of a clear distinction between slowing down due to conventional critical ordering and that due to glassiness, and provides a unified framework to assess the relative importance of specific local order and generic amorphous order in glass formation.

description: We celebrate the 50th anniversary of one the most classical models in probability theory. In this survey, we describe the main results of first passage percolation, paying special attention to the recent burst of advances of the past 5 years. The purpose of these notes is twofold. In the first chapters, we give self-contained proofs of seminal results obtained in the '80s and '90s on limit shapes and geodesics, while covering the state of the art of these questions. Second, aside from these classical results, we discuss recent perspectives and directions including (1) the connection between Busemann functions and geodesics, (2) the proof of sublinear variance under 2+log moments of passage times and (3) the role of growth and competition models. We also provide a collection of (old and new) open questions, hoping to solve them before the 100th birthday.

Demonstration of Compliance with the Radionuclide National Emission Standard for Hazardous Air Pollution at the National Institute of Environmental Health Sciences
Creators: name: Fitzgerald, William P., Jr.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: The objectives of this project were to determine how the radiation staff at the National Institute of Environmental Health Sciences could best demonstrate compliance with the radionuclide section of the National Emission Standard for Hazardous Air Pollutants and to collect the site specific data necessary to perform this task. The Environmental Protection Agency approved procedures for determining compliance with the radionuclide NESHAP were studied in detail. Equations that were utilized in the EPA approved compliance procedures to calculate the radionuclide concentrations in air and the concentration to dose screening factors are described in detail in this report. Site specific data for the NIEHS facility were collected and tabulated for use in this study and for future use by the facility staff. Attempts were made to demonstrate that NIEHS was in compliance with the radionuclide NESHAP for 1991 using the appropriate EPA approved compliance procedures. There are four EPA approved procedures (the Possession Table, the Concentration Table, the NCRP Screening Levels, and the Compliance Model) any one of which maybe used by a facility to demonstrate compliance. The first procedure is fairly simple and requires little input data, but uses very conservative methods for calculating the estimated dose. The procedures that follow are progressively more complex requiring more input data, making fewer conservative assumptions, and resulting in a more realistic dose estimate. Compliance with the radionuclide NESHAP was not demonstrated for NIEHS using the Possession Table, the Screening Level II, and the Screening Level III procedures. The NIEHS annual possession quantities of radionuclides were 143 times greater than allowed by the Possession Table procedure. The calculated dose to the most exposed receptor using the Screening Level II procedure was 50.7 mrem of which 10.2 mrem were from radionuclides of iodine. The calculated dose to the most exposed receptor using the Screening Level III procedure was 10.7 mrem of which 3.0 mrem were from radionuclides of iodine. The NIEHS facility was shown to be in compliance during 1991 with the radionuclide NESHAP using the Compliance Level procedure. Using this procedure the calculated dose to the most exposed receptor was 0.7 mrem of which 0.3 mrem were from radionuclides of iodine. These calculated dose values indicate that the staff at NIEHS are exempt from reporting radionuclide emissions to the EPA.
