Parent Report in Identifying Autism in Infants
Creators: name: Peterson, Lauren
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Parent report is often used in helping identify risk for developmental disabilities. However, limited research addresses the utility of parent/caregiver concerns in identifying risk for autism spectrum disorders (ASD). First Year Inventory (FYI) questionnaires (n=128) were sampled from an ongoing project, examining parent responses to open-ended questions about concerns regarding their 12-month-old. Parents of infants scoring at-risk on the FYI expressed significantly more concerns about their infants than parents of infants not at risk. Parents in both groups reported medical concerns most frequently. Among at-risk infants, infants whose parents had concerns did not exhibit significantly more ASD risk markers on a standardized ASD measure than infants whose parents had no concerns; however, those whose parents expressed concerns about their infants' social or language development had lower scores on a standardized communication measure. Findings in this study support the use of parent-reported concerns in identifying risk for ASD in infants.

Examination of selective broth culture media for the detection and quantification of Vibrio cholerae in drinking water using an adapted Compartment Bag Test
Creators: name: Lott, Megan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Cholera outbreaks may be mitigated by monitoring drinking waters for the bacterial disease agent, Vibrio cholerae. Present microbial methods for V. cholerae require advanced training and specialized equipment; these methods may not be appropriate for low-resource settings most vulnerable to cholera outbreaks. Our team hypothesized that the Aquagenx Compartment Bag Test (CBT) kit could be adapted for the direct detection and quantification of V. cholerae in drinking water in field settings. The present study evaluates selective culture media for adapted field use. The results of this study suggest that previously-described and commercially-available media are limited in specificity, exclusivity, and plating efficiency. We propose new selective broth culture media for use with the CBT. Preliminary results suggest that newly-proposed media demonstrate improved exclusivity over other existing culture media. These results support the further examination of broth media for direct quantification of V. cholerae with an adapted Cholera CBT.

description: Basic features of nonstrange vector and axial vector mesons are analyzed in the framework of a chiral quark model that includes nonlocal four fermion couplings. Unknown model parameters are determined from some input values of masses and decay constants, while nonlocal form factors are taken from a fit to lattice QCD results for effective quark propagators. Numerical results show a good agreement with the observed meson phenomenology.

description: We present a novel method for extrinsically calibrating a camera and a 2D Laser Rangefinder (LRF) whose beams are invisible from the camera image. We show that point-to-plane constraints from a single observation of a V-shaped calibration pattern composed of two non-coplanar triangles suffice to uniquely constrain the relative pose between two sensors. Next, we present an approach to obtain analytical solutions using point-to-plane constraints from single or multiple observations. Along the way, we also show that previous solutions, in contrast to our method, have inherent ambiguities and therefore must rely on a good initial estimate. Real and synthetic experiments validate our method and show that it achieves better accuracy than previous methods.

description: Let f: C --> P^3 be a general curve of genus g, mapped to P^3 via a general linear series of degree d; and let Q be a general (and thus smooth) quadric. In this paper, we show that the points of intersection f(C) \cap Q give a general collection of 2d points on Q, except for exactly six exceptional cases. We also prove similar theorems for every other pair (r, n) for which, except for only finitely many pairs (d, g), the intersection of a general curve of genus g mapped to P^r via a general linear series of degree d, with a general hypersurface S of degree n, is a general collection of dn points on S. As explained in arXiv:1809.05980, these results play a key role in the author's proof of the Maximal Rank Conjecture

On the microscopic origin and macroscopic implications of lane formation in mixtures of oppositely-driven particles

description: Colloidal particles of two types, driven in opposite directions, can segregate into lanes [Vissers et al. Soft Matter 7, 2352 (2011)]. This phenomenon can be reproduced by two-dimensional Brownian dynamics simulations of model particles [Dzubiella et al. Phys. Rev. E 65, 021402 (2002)]. Here we use computer simulation to assess the generality of lane formation with respect to variation of particle type and dynamical protocol. We find that laning results from rectification of diffusion on the scale of a particle diameter: oppositely-driven particles must, in the time taken to encounter each other in the direction of the drive, diffuse in the perpendicular direction by about one particle diameter. This geometric constraint implies that the diffusion constant of a particle, in the presence of those of the opposite type, grows approximately linearly with Peclet number, a prediction confirmed by our numerics over a range of model parameters. Such environment-dependent diffusion is statistically similar to an effective interparticle attraction; consistent with this observation, we find that oppositely-driven non-attractive colloids display features characteristic of the simplest model system possessing both interparticle attractions and persistent motion, the driven Ising lattice gas [Katz, Leibowitz, Spohn, J. Stat. Phys. 34, 497 (1984)]. These features include long-ranged correlations in the disordered regime, and a critical regime characterized by a change in slope of the particle current with Peclet number and by fluctuations that grow with system size. By analogy, we suggest that lane formation in the driven colloid system is in the macroscopic limit a phase transition, but that macroscopic phase separation would not occur in finite time upon starting from disordered initial conditions.
Mythical beasts: how queer bodies expand the religious imaginary
Creators: name: Goodwin, Megan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: The chiasmus of work on and with the body (askesis) and knowledge created by being-in-body (noesis) makes possible radically different thought about bodies and religiosity. Religion thus emerges as a site of meaning-making: an explanation for why one's body is the way that it is and a space in which to celebrate that body and use it in service to the divine. I read Foucault's theory of becoming-homosexual and Jantzen's religious philosophy of becoming-divine against the interviews and writings of Raven Kaldera, a male-to-female transsexual in the Northern Tradition. Kaldera's story is one of self-fashioning: he has shaped his body and his life to reflect his noetic experience of the divine – Hela, Norse patroness of the dead, requested that Kaldera serve as shaman to a sexually transgressive Norse Pagan community. I conclude that Kaldera instantiates a liberatory model of religiosity for those excluded by the western religious imaginary.

description: Abstract Background Overconsumption of energy from food contributes to high rates of overweight and obesity in many populations. A recent systematic review suggested that PACE labels may be effective at reducing energy selected and consumed, yet few of the studies were conducted in real-world settings. Methods A stepped-wedge randomised controlled trial to assess the impact of PACE labels on energy purchased from food and non-alcoholic drinks. The trial will take place in 10 cafeterias. The primary outcome is the total energy (kcal) purchased per day from intervention items using a pooled effect across all sites. Discussion This study will provide the most robust estimate to date of the effect size of PACE labels on the energy of food and drink purchased in cafeterias.

description: Background: Individuals with high-functioning autism (HFA) are likely to have auditory deficits related to emotional prosody. Aim: a) to investigate a possible deficit of vocal emotion recognition in children with HFA b) to examine the correlation of affective prosody with pitch perception and duration perception. Methodology: An auditory processing test battery was used, including Pitch Pattern Sequence Test (PPS) and Duration Pattern Sequence Test (DPS). To examine affective prosody, 19 sentences from the "AESDD" database were used. Population: 17 children aged 7-12 years. The clinical group consisted of 9 children diagnosed with HFA and the control group consisted of 8 typically developing children. Results: A statistically significant lower recognition performance of the emotion of joy was recorded in the clinical group compared to the control group. A strong correlation was found between psychoacoustic tests and prosody perception for each test.Conclusions: children with HFA at primary school age show deficits in joy recognition while they adequately recognize the other four basic emotions (anger, fear, sadness, disgust). The association of psychoacoustic cues (pitch perception/duration perception) with affective prosody is confirmed in this study.

description: On the road of searching for Majorana zero modes (MZMs) in topological insulator-based Josephson junctions, a highly-sought signature is the protected full transparency of electron transport through the junctions due to the existence of the MZMs, associated with complete gap closing between the electron-like and hole-like Andreev bound states (ABSs). Here, we present direct experimental evidence of gap closing and full transparency in single Josephson junctions constructed on the surface of three-dimensional topological insulator (3D TI) Bi$_2$Te$_3$. Our results demonstrate that the 2D surface of 3D TIs provides a promising platform for hosting and manipulating MZMs.

description: Quantum spin-orbital liquids are elusive strongly correlated states of matter that emerge from quantum frustration between spin and orbital degrees of freedom. A promising route towards the observation of those states is the creation of artificial Mott insulators where antiferromagnetic correlations between spins and orbitals can be designed. We show that Coulomb impurity lattices on the surface of gapped honeycomb substrates, such as graphene on SiC, can be used to simulate SU(4) symmetric spin-orbital lattice models. We exploit the property that massive Dirac fermions form mid-gap bound states with spin and valley degeneracies in the vicinity of a Coulomb impurity. Due to electronic repulsion, the antiferromagnetic correlations of the impurity lattice are driven by a super-exchange interaction with SU(4) symmetry, which emerges from the bound states degeneracy at quarter filling. We propose that quantum spin-orbital liquids can be engineered in artificially designed solid-state systems at vastly higher temperatures than achievable in optical lattices with cold atoms. We discuss the experimental setup and possible scenarios for candidate quantum spin-liquids in Coulomb impurity lattices of various geometries.

We obtain explicit high-probability bounds for the individual distances between certain signal eigenvalues of a graph's adjacency matrix and the corresponding eigenvalues of the model's edge probability matrix, even when the latter eigenvalues have multiplicity. Our results extend more broadly to the perturbation of singular values in the presence of quite general random matrix noise.

description: We study the inflation and the cosmological perturbations generated during the inflation in a local scale invariant model. The local scale invariant model introduces a vector field $S_μ$ in this theory. In this paper, for simplicity, we consider the temporal part of the vector field $S_t$. We show that the temporal part is associated with the slow roll parameter of scalar field. Due to local scale invariance, we have a gauge degree of freedom. In a particular gauge, we show that the local scale invariance provides sufficient number of e-foldings for the inflation. Finally, we estimate the power spectrum of scalar perturbation in terms of the parameters of the theory.

description: Strain-mediated voltage control of magnetization in piezoelectric/ferromagnetic systems is a promising mechanism to implement energy-efficient spintronic memory devices. Here, we demonstrate giant voltage manipulation of MgO magnetic tunnel junctions (MTJ) on a Pb(Mg1/3Nb2/3)0.7Ti0.3O3 (PMN-PT) piezoelectric substrate with (001) orientation. It is found that the magnetic easy axis, switching field, and the tunnel magnetoresistance (TMR) of the MTJ can be efficiently controlled by strain from the underlying piezoelectric layer upon the application of a gate voltage. Repeatable voltage controlled MTJ toggling between high/low-resistance states is demonstrated. More importantly, instead of relying on the intrinsic anisotropy of the piezoelectric substrate to generate the required strain, we utilize anisotropic strain produced using local gating scheme, which is scalable and amenable to practical memory applications. Additionally, the adoption of crystalline MgO-based MTJ on piezoelectric layer lends itself to high TMR in the strain-mediated MRAM devices.

description: We study a particular graded ring structure on the set of all loopfree matroids on a fixed labeled ground set, which occurs naturally in tropical geometry. The product is given by matroid intersection and the additive structure is defined by assigning to each matroid the indicator vector of its chains of flats. We show that this ring is generated in corank one, more precisely that any matroid can be written as a linear combination of products of corank one matroids. Moreover, we prove that a basis for the graded part of rank r matroids is given by the set of nested matroids and that the total number of these is a Eulerian number. Derksen's G-invariant then defines a Z-linear map on this ring, which implies for example that the Tutte polynomial is linear on it as well. Finally we show that the ring is the cohomology ring of the toric variety of the permutohedron and thus fulfills Poincaré duality.

description: We are interested in the large time behavior of the solutions to the growth-fragmentation equation. We work in the space of integrable functions weighted with the principal dual eigenfunction of the growth-fragmentation operator. This space is the largest one in which we can expect convergence to the steady size distribution. Although this convergence is known to occur under fairly general conditions on the coefficients of the equation, we prove that it does not happen uniformly with respect to the initial data when the fragmentation rate in bounded. First we get the result for fragmentation kernels which do not form arbitrarily small fragments by taking advantage of the Dyson-Phillips series. Then we extend it to general kernels by using the notion of quasi-compactness and the fact that it is a topological invariant.

description: In image deconvolution problems, the diagonalization of the underlying operators by means of the FFT usually yields very large speedups. When there are incomplete observations (e.g., in the case of unknown boundaries), standard deconvolution techniques normally involve non-diagonalizable operators, resulting in rather slow methods, or, otherwise, use inexact convolution models, resulting in the occurrence of artifacts in the enhanced images. In this paper, we propose a new deconvolution framework for images with incomplete observations that allows us to work with diagonalized convolution operators, and therefore is very fast. We iteratively alternate the estimation of the unknown pixels and of the deconvolved image, using, e.g., an FFT-based deconvolution method. This framework is an efficient, high-quality alternative to existing methods of dealing with the image boundaries, such as edge tapering. It can be used with any fast deconvolution method. We give an example in which a state-of-the-art method that assumes periodic boundary conditions is extended, through the use of this framework, to unknown boundary conditions. Furthermore, we propose a specific implementation of this framework, based on the alternating direction method of multipliers (ADMM). We provide a proof of convergence for the resulting algorithm, which can be seen as a "partial" ADMM, in which not all variables are dualized. We report experimental comparisons with other primal-dual methods, where the proposed one performed at the level of the state of the art. Four different kinds of applications were tested in the experiments: deconvolution, deconvolution with inpainting, superresolution, and demosaicing, all with unknown boundaries.

description: Despite their appealing features, models with gauge-mediated supersymmetry breaking (GMSB) typically present a high degree of fine-tuning, due to the initial absence of the top trilinear scalar couplings, $A_t=0$. In this paper, we carefully evaluate such a tuning, showing that is worse than per mil in the minimal model. Then, we examine some existing proposals to generate $A_t\neq 0$ term in this context. We find that, although the stops can be made lighter, usually the tuning does not improve (it may be even worse), with some exceptions, which involve the generation of $A_t$ at one loop or tree level. We examine both possibilities and propose a conceptually simplified version of the latter; which is arguably the optimum GMSB setup (with minimal matter content), concerning the fine-tuning issue. The resulting fine-tuning is better than one per mil, still severe but similar to other minimal supersymmetric standard model constructions. We also explore the so-called "little $A_t^2/m^2$ problem", i.e. the fact that a large $A_t$-term is normally accompanied by a similar or larger sfermion mass, which typically implies an increase in the fine-tuning. Finally, we find the version of GMSB for which this ratio is optimized, which, nevertheless, does not minimize the fine-tuning.

description: We study the problem of estimating a low-rank positive semidefinite (PSD) matrix from a set of rank-one measurements using sensing vectors composed of i.i.d. standard Gaussian entries, which are possibly corrupted by arbitrary outliers. This problem arises from applications such as phase retrieval, covariance sketching, quantum space tomography, and power spectrum estimation. We first propose a convex optimization algorithm that seeks the PSD matrix with the minimum $\ell_1$-norm of the observation residual. The advantage of our algorithm is that it is free of parameters, therefore eliminating the need for tuning parameters and allowing easy implementations. We establish that with high probability, a low-rank PSD matrix can be exactly recovered as soon as the number of measurements is large enough, even when a fraction of the measurements are corrupted by outliers with arbitrary magnitudes. Moreover, the recovery is also stable against bounded noise. With the additional information of an upper bound of the rank of the PSD matrix, we propose another non-convex algorithm based on subgradient descent that demonstrates excellent empirical performance in terms of computational efficiency and accuracy.

description: Η υπογονιμότητα αποτελεί μία παθολογική κατάσταση η οποία επηρεάζει ένα σημαντικό ποσοστό των ζευγαριών που προσπαθούν να τεκνοποιήσουν και το μισό των περιπτώσεων αυτών οφείλεται στην ανδρική υπογονιμότητα. Αρκετές φορές, τα αίτια της ανδρικής υπογονιμότητας είναι άγνωστα. Επομένως, είναι επιτακτική ανάγκη να βρεθούν νέα εργαλεία για την ανεύρεση των αιτιών και την αντιμετώπιση της. Η επιγενετική είναι η μελέτη των αλλαγών που συμβαίνουν στο γονιδίωμα και επηρεάζουν την έκφραση των γονιδίων χωρίς την μεταλλαγή των αζωτούχων βάσεων των νουκλεϊκών οξέων. Ένας από τους πιο εκτενώς μελετημένους μηχανισμούς της επιγενετικής είναι η μεθυλίωση του DNA. Η ελαττωματική μεθυλίωση σε αποτυπωμένα γονίδια και μη, δείχνει να συσχετίζεται με την υπογονιμότητα όπως αντικατοπτρίζεται στο σπερμοδιάγραμμα. Οι περιβαλλοντικοί παράγοντες και ο τρόπος ζωής αποδεδειγμένα επηρεάζουν την ποιότητα του σπέρματος και πιθανόν την έκφραση γονιδίων που ρυθμίζουν την σπερματογένεση σε επιγενετικό επίπεδο. Παρόλα αυτά, η σχέση της μεθυλίωσης του DNA και της ανδρικής υπογονιμότητας δεν είναι ξεκάθαρη, καθώς δεν υπάρχει επαρκής μηχανισμός που να τα συνδέει. Το οξειδωτικό στρες θα μπορούσε να είναι ένας από αυτούς τους μηχανισμούς καθώς είναι πλέον γνωστό ότι οι ελεύθερες ρίζες οξυγόνου δύναται να καταστρέψουν τη δομή του δίκλωνου μορίου του DNA.
description: Infertility is a state that affects a decent percentage of couples and 50% of the infertility cases are caused by male infertility. Male infertility is oftentimes unexplained, creating a need for new tools in diagnosis and treatment. Epigenetics is the study of the changes that occur on the genome and affect the expression of genes, without the interference of mutations. DNA methylation is one of the most well studied mechanisms of epigenetics. Aberrant methylation of imprinted and non-imprinted genes seems to correlate with abnormal observations in spermogram. Factors like one’s lifestyle and the environment play a pivotal role on the quality of the sperm and they might affect genes that are responsible for spermatogenesis on an epigenetic level. Nevertheless, the relationship between male infertility and DNA methylation is not properly defined as a detailed mechanism of action is not yet established. Oxidative stress is a viable candidate as an intermediate between methylation and infertility because of the damage it is able to cause on DNA strands.

description: Professional associations provide resources for members to enhance their careers. Although dental hygiene has been licensed profession in Saudi Arabia since 1980, there is no professional association. Purpose: To assess attitudes and opinions of Saudi dental hygienists regarding establishing a professional association. Methods: After IRB exemption, a cross sectional survey using Qualtrics was utilized A link to the survey was sent to 101 Saudi dental hygienists. Results: Seventy-seven responded a response rate of 70.3%. Most (91.5%, n=65) favored the establishment of a professional association. In addition, 88.1% (n = 59) responded that it would promote professional development and 86.6% (n=58) agreed that their professional needs could be met. Half of those who opposed its creation believed it would promote professional development and meet their professional needs. Conclusion: Saudi dental hygienists support the establishment of a professional association and feel that it would promote the profession and meet their professional needs.

description: Pump-probe techniques with high temporal resolution allow one to drive a system of interest out of equilibrium and at the same time, probe its properties. Recent advances in these techniques open the door to studying new, non-equilibrium phenomena such as Floquet topological insulators and superconductors. These advances also necessitate the development of theoretical tools for understanding the experimental findings and predicting new ones. In the present work, we provide a theoretical foundation to understand the non-equilibrium behavior of a Dirac system. We present detailed numerical calculations and simple analytic results for the evolution of a Dirac system irradiated by light. These results are framed intuitively by appealing to the recently revitalized notion of side-bands. We find that, under the application of circularly polarized light, a Dirac point only ever splits into two copies of sidebands. Meanwhile, the application of linearly polarized light leaves the Dirac point intact while producing side bands. Our immediate interest in this work is in connection to time and angle resolved photoemission experiments, where we find excellent qualitative agreement between our results and those in the literature. However, our results are general and may prove useful beyond this particular application and should be relevant to other pump-probe experiments.

description: Mass spectra of excited states of the singly charmed baryons are calculated using the hypercentral description of three body system. The baryon consist of a charm quark and light quarks (u, d and s) are studied in the framework of QCD motivated constituent quark model. The form of confinement potential is hyper coloumb plus power potential with potential index $ν$, varying from 0.5 to 2.0. The first order correction to the confinement potential is also incorporated in this approach. The radial as well as orbital excited state masses of $Σ_{c}^{++}, Σ_{c}^+, Σ_{c}^0, Ξ_c^+, Ξ_c^0, Λ_c^+, Ω_c^0$ baryons, are reported in this paper. We have incorporated spin-spin, spin-orbit and tensor interactions perturbatively in the present study. The semi-electronic decay of $Ω_c$ and $Ξ_c$ are also calculated using the spectroscopic parameters of these baryons. The computed results are compared with other theoretical predictions as well as with the available experimental observations. We also construct the Regge trajectory in ($n_r$, $M^{2}$) and (J, $M^{2}$) plane for these baryons.

description: The physics of a planar chiral $p\pm i p$ superconductor is studied for various vortex configurations. The occurrence of vortex quasi-particle bound states is exposed together with their ensuing collective properties, such as sub-gap bands induced by inter-vortex tunneling. A general method to diagonalize the Hamiltonian of a superconductor in the presence of a vortex lattice is developed, that employs only smooth gauge transformations. It renders the Hamiltonian to be periodic (thus allowing the use of a Bloch theorem) and enables the treatment of systems with vortices of finite radii. The pertinent anomalous charge response $c_{xy}$ is calculated (using the Streda formula), and reveals that it contains a quantized contribution. This is attributed to the response to the nucleation of vortices, from which we deduce the system's quantum phase.

description: We present a detailed analysis of the properties of twisted, force-free magnetospheres of non-rotating neutron stars, which are of interest in the modelling of magnetar properties and evolution. In our models the magnetic field smoothly matches to a current-free (vacuum) solution at some large external radius, and they are specifically built to avoid pathological surface currents at any of the interfaces. By exploring a large range of parameters, we find a few remarkable general trends. We find that the total dipolar moment can be increased by up to $40\%$ with respect to a vacuum model with the same surface magnetic field, due to the contribution of magnetospheric currents to the global magnetic field. Thus, estimates of the surface magnetic field based on the large-scale dipolar braking torque are slightly overestimating the surface value by the same amount. Consistently, there is a moderate increase in the total energy of the model with respect to the vacuum solution of up to $25\%$, which would be the available energy budget in the event of a fast, global magnetospheric reorganization commonly associated with magnetar flares. We have also found the interesting result of the existence of a critical twist ($φ_{\rm max} \lesssim 1.5$ rad), beyond which we cannot find any more numerical solutions. Combining the models considered in this paper with the evolution of the interior of neutron stars will allow us to study the influence of the magnetosphere on the long-term magnetic, thermal, and rotational evolution.

Creators: name: Diaz, Patricia Ines

Year: 2008

description: Campylobacter rectus is as a possible cause in the association between periodontal disease and adverse pregnancy outcomes. In this study we evaluated the effect of a distant infection with Campylobacter rectus on the fetal placental unit at the murine gestational day E14.5 and characterized the in vitro interactions of C. rectus with cells similar to those found in the placenta, ie. trophoblast and endothelial cells. Scarce infection with C. rectus was directly visualized within the placentas of challenged mice, which presented with decreased placental weight and fetal-placental unit weight and altered placental morphology. C. rectus infection dysregulated angiogenic gene expression in the placenta and in trophoblast murine cells in vitro. C. rectus was also capable of invasion of human trophoblast and endothelial cells while was only able to penetrate cell junctions in murine trophoblasts. The results illustrate the potential for C. rectus to affect placental/fetal development in mice and humans.
