Was the soft X-ray flare in NGC 3599 due to an AGN disc instability or a delayed tidal disruption event?

description: We present unpublished data from a tidal disruption candidate in NGC 3599 which show that the galaxy was already X-ray bright 18 months before the measurement which led to its classification. This removes the possibility that the flare was caused by a classical, fast-rising, short-peaked, tidal disruption event. Recent relativistic simulations indicate that the majority of disruptions will actually take months or years to rise to a peak, which will then be maintained for longer than previously thought. NGC 3599 could be one of the first identified examples of such an event. The optical spectra of NGC 3599 indicate that it is a low-luminosity Seyfert/LINER with L_bol~10^40 ergs/s The flare may alternatively be explained by a thermal instability in the accretion disc, which propagates through the inner region at the sound speed, causing an increase of the disc scale height and local accretion rate. This can explain the <9 years rise time of the flare. If this mechanism is correct then the flare may repeat on a timescale of several decades as the inner disc is emptied and refilled.

Probabilistic Diffusion in Random Network Graphs

description: In this paper, we consider a random network such that there could be a link between any two nodes in the network with a certain probability (plink). Diffusion is the phenomenon of spreading information throughout the network, starting from one or more initial set of nodes (called the early adopters). Information spreads along the links with a certain probability (pdiff). Diffusion happens in rounds with the first round involving the early adopters. The nodes that receive the information for the first time are said to be covered and become candidates for diffusion in the subsequent round. Diffusion continues until all the nodes in the network have received the information (successful diffusion) or there are no more candidate nodes to spread the information but one or more nodes are yet to receive the information (diffusion failure). On the basis of exhaustive simulations conducted in this paper, we observe that for a given plink and pdiff values, the fraction of successful diffusion attempts does not appreciably change with increase in the number of early adopters; whereas, the average number of rounds per successful diffusion attempt decreases with increase in the number of early adopters. The invariant nature of the fraction of successful diffusion attempts with increase in the number of early adopters for a random network (for fixed plink and pdiff values) is an interesting and noteworthy observation (for further research) and it has not been hitherto reported in the literature.

Year: 2013

description: Middle school is a time of significant transition for students, and support is needed to ensure school success during this time. This evaluation study examined student outcomes within the context of an after-school program designed to support student success. Participants were 132 middle school students participating in the program at seven different middle schools. Student course grades, school attendance, and student disciplinary actions were examined over the course of program participation, taking into account student attendance in the after-school program. Findings indicate no statistically significant differences in student Mathematics achievement, school attendance, and student behavior from the beginning of the program year to the end. A slight statistically significant difference was found in student Language Arts grades throughout the program year. Results from correlational analysis indicated no relationship between student attendance in the program and outcome variables. Findings were discussed and recommendations were provided for program improvement and future studies.

description: The mass discrepancy acceleration relation (MDAR) describes the coupling between baryons and dark matter (DM) in galaxies: the ratio of total-to-baryonic mass at a given radius anti-correlates with the acceleration due to baryons. The MDAR has been seen as a challenge to the $Λ$CDM galaxy formation model, while it can be explained by Modified Newtonian Dynamics. In this Letter we show that the MDAR arises in a $Λ$CDM cosmology once observed galaxy scaling relations are taken into account. We build semi-empirical models based on $Λ$CDM haloes, with and without the inclusion of baryonic effects, coupled to empirically motivated structural relations. Our models can reproduce the MDAR: specifically, a mass-dependent density profile for DM haloes can fully account for the observed MDAR shape, while a universal profile shows a discrepancy with the MDAR of dwarf galaxies with $\rm M^{\star}$$

The continuing significance of region: an exploration of the relationship between residence, regional identity, symbolic understanding, and racial tolerance
Creators: name: Gibson, Kristin Noelle
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: There continues to be a significant difference in the level of racial tolerance found in the South vs. the non-South heading into the new millennia; however despite the number of articles that use region as a possible causal factor of racial attitudes, beyond serving as a demographic control, there is a lack of discussion regarding why region is expected and does have an impact on attitudes. I am suggesting that regional identification and symbolic understanding of the region might explain why southerners exhibit greater racial intolerance than residents of other regions. Both measures offer a way of empirically testing how peoples' attitudes might be linked to their identity as a member of a regional group. Using a combination of bivariate crosstabulation and logistic regression, this paper assesses what effect the addition of the mediating mechanisms has on the original effect of residence on attitudes.

description: Graph Isomorphism is one of the classical problems of graph theory for which no deterministic polynomial-time algorithm is currently known, but has been neither proven to be NP-complete. Several heuristic algorithms have been proposed to determine whether or not two graphs are isomorphic (i.e., structurally the same). In this research, we propose to use the sequence (either the non-decreasing or nonincreasing order) of eigenvector centrality (EVC) values of the vertices of two graphs as a precursor step to decide whether or not to further conduct tests for graph isomorphism. The eigenvector centrality of a vertex in a graph is a measure of the degree of the vertex as well as the degrees of its neighbors. We hypothesize that if the non-increasing (or non-decreasing) order of listings of the EVC values of the vertices of two test graphs are not the same, then the two graphs are not isomorphic. If two test graphs have an identical non-increasing order of the EVC sequence, then they are declared to be potentially isomorphic and confirmed through additional heuristics. We test our hypothesis on random graphs (generated according to the Erdos-Renyi model) and we observe the hypothesis to be indeed true: graph pairs that have the same sequence of non-increasing order of EVC values have been confirmed to be isomorphic using the well-known Nauty software.

description: In this analysis we illustrate how the relatively new emission mechanism known as spinning dust can be used to characterize dust grains in the interstellar medium. We demonstrate this by using spinning dust emission observations to constrain the abundance of very small dust grains (a $\lesssim$ 10nm) in a sample of Galactic cold cores. Using the physical properties of the cores in our sample as inputs to a spinning dust model, we predict the expected level of emission at a wavelength of 1cm for four different very small dust grain abundances, which we constrain by comparing to 1cm CARMA observations. For all of our cores we find a depletion of very small grains, which we suggest is due to the process of grain growth. This work represents the first time that spinning dust emission has been used to constrain the physical properties of interstellar dust grains.

4 pairs of 4-component spinors for SL(4,C), their transformation properties and SL(4,C)SL(4,C)*=SO(3,1) connection

Subjects: SL(4,C), spinor metric for SL(4,C), SL(2,C), SO(3,1), 4-component spinors, 4x4 versions of Pauli matrices, 4-vectors, coherency matrix, quaternions, factorization of the Lorentz transformation, Jones matrix, Mueller matrix

description: In certain basis, SL(3,1) can be written as a matrix direct product of SL(2,C) and SL(2,C)*. One direct consequence of this relation is that SO(3,1) can also be conceived as a commutative matrix product of SL(4,C) and SL(4,C)*. For example, in polarization optics, any non-singular, non-depolarizing Mueller matrix, M, that belongs to the proper orthochronous Lorentz group is equal to the commutative product of a 4x4 complex matrix Z and its complex conjugate, M=ZZ*=Z*Z, where Z is an element of SL(4,C) and it is the 4x4 analogue of the 2x2 Jones matrix of SL(2,C). In this note we define a spinor-Minkowski metric for SL(4,C). It is not a trivial generalization of the SL(2,C) metric, it involves the Minkowski metric. We define 4x4 versions of the Pauli matrices and their 4-component generalized contravariant eigenvectors. We show that dotted versions of these eigenvectors transform as right-chiral spinors and their covariant counterparts transform as left-chiral spinors under SL(4,C). The outer products of pairwise combinations of these eigenvectors can be associated with the 4-vector of the Minkowski space.
Cloud Structure of the Nearest Brown Dwarfs II: High-amplitude variability for Luhman 16 A and B in and out of the 0.99 micron FeH feature

description: The re-emergence of the 0.99 $μ$m FeH feature in brown dwarfs of early- to mid-T spectral type has been suggested as evidence for cloud disruption where flux from deep, hot regions below the Fe cloud deck can emerge. The same mechanism could account for color changes at the L/T transition and photometric variability. We present the first observations of spectroscopic variability of brown dwarfs covering the 0.99 $μ$m FeH feature. We observed the spatially resolved very nearby brown dwarf binary WISE J104915.57-531906.1 (Luhman 16AB), a late-L and early-T dwarf, with HST/WFC3 in the G102 grism at 0.8-1.15 $μ$m. We find significant variability at all wavelengths for both brown dwarfs, with peak-to-valley amplitudes of 9.3% for Luhman 16B and 4.5% for Luhman 16A. This represents the first unambiguous detection of variability in Luhman 16A. We estimate a rotational period between 4.5 and 5.5 h, very similar to Luhman 16B. Variability in both components complicates the interpretation of spatially unresolved observations. The probability for finding large amplitude variability in any two brown dwarfs is less than 10%. Our finding may suggest that a common but yet unknown feature of the binary is important for the occurrence of variability. For both objects, the amplitude is nearly constant at all wavelengths except in the deep K I feature below 0.84 $μ$m. No variations are seen across the 0.99 $μ$m FeH feature. The observations lend strong further support to cloud height variations rather than holes in the silicate clouds, but cannot fully rule out holes in the iron clouds. We re-evaluate the diagnostic potential of the FeH feature as a tracer of cloud patchiness.

description: We study the link between atomic motion and exciton transport in flexible Rydberg aggregates, assemblies of highly excited light alkali atoms, for which motion due to dipole-dipole interaction becomes relevant. In two one-dimensional atom chains crossing at a right angle adiabatic exciton transport is affected by a conical intersection of excitonic energy surfaces, which induces controllable non-adiabatic effects. A joint exciton/motion pulse that is initially governed by a single energy surface is coherently split into two modes after crossing the intersection. The modes induce strongly different atomic motion, leading to clear signatures of non-adiabatic effects in atomic density profiles. We have shown how this scenario can be exploited as an exciton switch, controlling direction and coherence properties of the joint pulse on the second of the chains [K.~Leonhardt {\it et al.}, Phys.~Rev.~Lett. {\bf 113} 223001 (2014)]. In this article we discuss the underlying complex dynamics in detail, characterise the switch and derive our isotropic interaction model from a realistic anisotropic one with the addition of a magnetic bias field.

Monitored Steady State Excitation and Recovery (MSSER) radiation force imaging of engineered tissue constructs
Creators: name: Richardson, Aaron C.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: Production of engineered bone tissue requires integration of synthetic and natural materials and ideal chemical and mechanical stimulation. More understanding of changes in mechanical properties of these tissues during differentiation is needed. Current tensile testing methods result in destruction of tissue constructs. A non-destructive testing method is desired. Monitor Steady State Excitation and Recovery, MSSER, an ultrasound imaging based elastography method, uses prolonged acoustic force to displace tissue while monitoring changes in strain during force application. MSSER, along with the underdamped harmonic oscillation model, was used to determine the elastic modulus of tissue constructs. Localized elastic modulus values were calculated using MSSER for tissue constructs grown in osteogenic and complete (non-osteogenic) growth media. Images showing elastic modulus values were produced. Validation of elastic modulus images were done performing calcium digestion on tissue constructs. MSSER hopes to provide a non-invasive testing method, allow for localized measurements, and aid in calcium detection.

Time for a check-up: mapping environmental diseases in the United Arab Emirates using Bayesian Maximum Entropy and the Waller model
Creators: name: Hasan, Mejs
Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: When a health authority wants to identify areas disproportionately affected by a disease, a good starting point is to map crude health data. However, data from small populations can be unstable and overestimate the disease risk, or data may be incomplete. These problems can be partially remedied through statistical smoothers. Two spatiotemporal mapping methods are compared in this study, the Waller model and Bayesian Maximum Entropy (BME). The Waller model belongs to the established family of Bayesian hierarchical models, `hierarchical' because uncertainty within the model is measured indefinitely through a series of parameters and hyperparameters. BME, crafted at UNC, uses covariance to supply prior knowledge, and ignores uncertainty in prior parameters. These methods were applied to 69,000 records of cardiopulmonary medical visits in the United Arab Emirates. BME was found to be a stronger smoother of health data. Rates of medical visits were found to rise sharply during summer months.

Chess as a Key to Solving Nabokov’s Korol’, dama, valet
Creators: name: Slater, James Murray
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: This thesis examines the role of chess in Nabokov's novel, Korol', dama, valet, and how the struggle between the narrator and the protagonist, Martha-Marta, can be justified by using chess as a key. The first portion of my analysis is based on the role of the diegetic narrator in an attempt to subvert Martha's movements toward autonomy. In explaining the narrator's subversion of Martha, I explore the nature of the protagonists, the movement of the narrative, and the structure and parameters of the novel in relation to it being a figurative game of chess. Furthermore, Martha's attempts at dominance are examined in connection to the concept of past-reconstruction. I conclude my analysis by ushering in unifying intersections of plot and characterization in Nabokov's later work.
Reading disabilities in British Columbia after Moore v. British Columbia (2012)

Subjects: subject: Reading disability

description: The purpose of this study was to investigate how a group of special education teachers in British Columbia provide remedial support to students identified as having a reading disability (RD). Considering the Moore v. British Columbia (2012) ruling the location of the support was of interest. To achieve the study’s purpose, the author of the current study set out to determine how a group of special educators offer remediation and what this remediation looks like. A mixed-methods survey was distributed to all attendees of the learning assistance teachers’ association (LATA) conference in Vancouver, BC on October 23, 2016. Twenty-five completed surveys were returned. Results indicate that most respondents prefer to provide pullout remediation, a wide array of strategies were used when providing support, and that the Moore v. British Columbia has made little difference to how special educators provide service. Areas for further research include a deeper analysis of why preferences exist and a broadening of the survey recipients to include educational assistants and administrators.

A Conservation Assessment of Packera millefolium, a Southern Appalachian Endemic
Creators: name: Gramling, Andrea Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Packera millefolium is a rare species endemic to rock outcrops in the southern Appalachians thought to hybridize with its more common congener, P. anonyma. Morphological analyses and cross-pollination experiments were used to verify the existence of the hybrid Packera ×memmingeri. Preliminary results show that introgression between P. millefolium and P. anonyma is probable at some locations. Information on population size and the presence or absence of hybrids was compiled for populations of P. millefolium from historical records and on-site surveys. An analysis of this data shows that hybrids occur at approximately 40% of the populations in North and South Carolina. The data also suggests that anthropogenic disturbance of the landscape surrounding once isolated populations of P. millefolium might have broken down the ecological barriers that historically prevented gene flow between P. millefolium and P. anonyma. The management implications for P. millefolium due to hybridization with P. anonyma are discussed.

description: The sub-linear expectation or called G-expectation is a nonlinear expectation having advantage of modeling non-additive probability problems and the volatility uncertainty in finance. Let $\{X_n;n\ge 1\}$ be a sequence of independent random variables in a sub-linear expectation space $(Ω, \mathscr{H}, \widehat{\mathbb E})$. Denote $S_n=\sum_{k=1}^n X_k$ and $V_n^2=\sum_{k=1}^n X_k^2$. In this paper, a moderate deviation for self-normalized sums, that is, the asymptotic capacity of the event $\{S_n/V_n \ge x_n \}$ for $x_n=o(\sqrt{n})$, is found both for identically distributed random variables and independent but not necessarily identically distributed random variables. As an applications, the self-normalized laws of the iterated logarithm are obtained.

description: In this paper, we study a new application of the positive Grassmanian to Wilson loop diagrams (or MHV diagrams) for scattering amplitudes in N=4 Super Yang-Mill theory ($N=4$ SYM). There has been much interest in studying this theory via the positive Grassmanians using BCFW recursion. This is the first attempt to study MHV diagrams for planar Wilson loop calculations (or planar amplitudes) in terms of positive Grassmannians. We codify Wilson loop diagrams completely in terms of matroids. This allows us to apply the combinatorial tools in matroid theory used to identify positroids, (non-negative Grassmannians), to Wilson loop diagrams. In doing so, we find that certain non-planar Wilson loop diagrams define positive Grassmannians. While non-planar diagrams do not have physical meaning, this finding suggests that they may have value as an algebraic tool, and deserve further investigation.

description: Magnetic resonance imaging (MRI) is a versatile imaging technique that allows different contrasts depending on the acquisition parameters. Many clinical imaging studies acquire MRI data for more than one of these contrasts---such as for instance T1 and T2 weighted images---which makes the overall scanning procedure very time consuming. As all of these images show the same underlying anatomy one can try to omit unnecessary measurements by taking the similarity into account during reconstruction. We will discuss two modifications of total variation---based on i) location and ii) direction---that take structural a priori knowledge into account and reduce to total variation in the degenerate case when no structural knowledge is available. We solve the resulting convex minimization problem with the alternating direction method of multipliers that separates the forward operator from the prior. For both priors the corresponding proximal operator can be implemented as an extension of the fast gradient projection method on the dual problem for total variation. We tested the priors on six data sets that are based on phantoms and real MRI images. In all test cases exploiting the structural information from the other contrast yields better results than separate reconstruction with total variation in terms of standard metrics like peak signal-to-noise ratio and structural similarity index. Furthermore, we found that exploiting the two dimensional directional information results in images with well defined edges, superior to those reconstructed solely using a priori information about the edge location.

Epidemiology of Cervical Muscle Strains in High School and Collegiate Male Collision Athletes
Creators: name: Lee, Katherine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Cervical muscle strains are an often-overlooked injury, with neck-/spine-related research typically focusing on spinal cord and vertebral injuries. Using data from two high school and one collegiate sports injury surveillances systems, this thesis describes the epidemiology of cervical muscle strains in four male sports in which contact is legal (football, ice hockey, lacrosse, and wrestling).  Injury counts, injury rates, injury rate ratios, and distributions of participation restriction time, injury mechanism, and injury activity were examined by sport and level of play.  At both the high school and collegiate levels, football had the highest cervical muscle strain injury rate. Most injuries occurred in competitions, were non-time loss (<24 hours of participation restriction time), and were due to player contact.  Despite the low incidence, it is important to consider the development and evaluation of prevention strategies that may help reduce the negative effects sustained by athletes who suffer cervical muscle strains.
