description: We study three high magnification microlensing events, generally recognized as probable caustic crossings, in the optical light curves of the multiply imaged quasar Q 2237+0305. We model the light curve of each event as the convolution of a standard thin disk luminosity profile with a straight fold caustic. We also allow for a linear gradient that can account for an additional varying background effect of microlensing. This model not only matches noticeably well the global shape of each of the three independent microlensing events but also gives remarkably similar estimates for the disk size parameter. The measured average half-light radius, $R_{1/2}=(3.0\pm 1.5)\sqrt{M/0.3M\odot}$ light-days, agrees with previous estimates. In the three events, the core of the magnification profile exhibits "fine structure" related to the innermost region of the accretion disk (located at a radial distance of $2.7\pm 1.4$ Schwarzschild radii according to our measurement). Relativistic beaming at the internal rim of the accretion disk can explain the shape and size of the fine structure, although alternative explanations are also possible. This is the first direct measurement of the size of a structure, likely the innermost stable circular orbit, at $\sim 3$ Schwarzschild radii in a quasar accretion disk. The monitoring of thousands of lensed quasars with future telescopes will allow the study of the event horizon environment of black holes in hundreds of quasars in a wide range of redshifts $(0.5

description: We numerically investigate the generation of solitons in current-biased long Josephson junctions in relation to the superconducting lifetime and the voltage drop across the device. The dynamics of the junction is modelled with a sine-Gordon equation driven by an oscillating field and subject to an external non-Gaussian noise. A wide range of $α$-stable Lévy distributions is considered as noise source, with varying stability index $α$ and asymmetry parameter $β$. In junctions longer than a critical length, the mean switching time (MST) from superconductive to the resistive state assumes a values independent of the device length. Here, we demonstrate that such a value is directly related to the mean density of solitons which move into or from the washboard potential minimum corresponding to the initial superconductive state. Moreover, we observe: (i) a connection between the total mean soliton density and the mean potential difference across the junction; (ii) an inverse behavior of the mean voltage in comparison with the MST, with varying the junction length; (iii) evidences of non-monotonic behaviors, such as stochastic resonant activation and noise enhanced stability, of MST versus the driving frequency and noise intensity for different values of $α$ and $β$; (iv) finally, these non-monotonic behaviors are found to be related to the mean density of solitons formed along the junction.

description: There is a growing evidence base supporting the benefits of working in partnership with patients and their families in evaluating healthcare services. Despite this, children and young people are often overlooked. This is particularly so for those being care for in the community health service setting. An initial review of the literature identified little is known about strategies and approaches being implemented to partner with, and evaluate children’s and young people’s care in the community health setting. The aim of this scoping review is therefore to identify and describe the partnership with children and young people in the evaluation of adolescent care in a community health setting.

description: The magnon disp ersion in Ca2RuO4 has been determined by inelastic neutron scattering on single crytals containing 1% of Ti. The dispersion is well described by a conventional Heisenberg model suggesting a local moment model with nearest neighbor interaction of J=8 meV. Nearest and next-nearest neighbor interaction as well as inter-layer coupling parameters are required to properly describe the entire dispersion. Spin-orbit coupling induces a very large anisotropy gap in the magnetic excitations in apparent contrast with a simple planar magnetic model. Orbital ordering breaking tetragonal symmetry, and strong spin-orbit coupling can thus be identified as important factors in this system.

description: The Academic Progress Rate is a metric of points earned by student-athletes for retention and eligibility. Student-athletes that leave school academically ineligible receive a score of 0/2. This study sought to identify common characteristics of the 0/2 student-athletes of the Atlantic Coast Conference. Six ACC schools participated in the study, providing data on 190 student-athletes that were identified as 0/2 over the past four years. A general profile of an 0/2 student-athlete is a Black male, leaving during the 4th or 5th year of enrollment, having exhausted athletic eligibility, who was academically eligible the term prior to the 0/2 term. The most important finding of the study was that the greatest majority of student-athletes fail out of school in their last semester of eligibility.

description: Noisy 3D point clouds arise in many applications. They may be due to errors when constructing a 3D model from images or simply to imprecise depth sensors. Point clouds can be given geometrical structure using graphs created from the similarity information between points. This paper introduces a technique that uses this graph structure and convex optimization methods to denoise 3D point clouds. A short discussion presents how those methods naturally generalize to time-varying inputs such as 3D point cloud time series.

Children’s Sensory Experiences and Family Occupations

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: This qualitative study employed a grounded theory approach to data analysis to discover what effect, if any, children's sensory experiences have on family occupations. A grounded theory approach was chosen because existing occupational therapy and occupational science literature does not provide a theory to account for the effect of children's sensory experiences on family occupations. Parents of 12 children were interviewed. Six of the children were typically developing and six children had autism. The interviews were transcribed verbatim and analyzed using open, axial, and selective coding techniques. Three themes were identified to explain how children's sensory experiences affect family occupations. Children's sensory experiences affect: (a) what a family chooses to do or not do; (b) how the family prepares; and (c) the extent to which experiences, meaning, and feelings are shared.

description: Results from the NA49 experiment at the CERN SPS are presented on event-by-event transverse momentum and multiplicity fluctuations of charged particles, produced at forward rapidities in central Pb+Pb interactions at beam momenta 20$A$, 30$A$, 40$A$, 80$A$, and 158$A$ GeV/c, as well as in systems of different size ($p+p$, C+C, Si+Si, and Pb+Pb) at 158$A$ GeV/c. This publication extends the previous NA49 measurements of the strongly intensive measure $Φ_{p_T}$ by a study of the recently proposed strongly intensive measures of fluctuations $Δ[P_T, N]$ and $Σ[P_T, N]$. In the explored kinematic region transverse momentum and multiplicity fluctuations show no significant energy dependence in the SPS energy range. However, a remarkable system size dependence is observed for both $Δ[P_T, N]$ and $Σ[P_T, N]$, with the largest values measured in peripheral Pb+Pb interactions. The results are compared with NA61/SHINE measurements in $p+p$ collisions, as well as with predictions of the UrQMD and EPOS models.

Nucleus accumbens neuronal activity during a sensory preconditioning task
Creators: name: Cerri, Domenic Hayden
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: The nucleus accumbens (NAc) is involved in associative learning and motivated behavior but its role in Sensory Preconditioning (SPC) remains unknown. Here, electrophysiological recordings were taken from the NAc core while rats performed three phases of a SPC task. During Preconditioning (phase 1), the NAc was more activated by a stimulus that was preceded by another stimulus, versus the same stimulus presented in isolation, suggesting that the NAc may encode information about neutral cue associations. During First-Order Conditioning (FOC) (phase 2), animals readily acquired the association between the conditioned and unconditioned stimulus, and this information was processed by distinct populations of NAc neurons. At SPC Test (phase 3), animals showed behavioral evidence of SPC; however, NAc activity did not track this behavior. These findings show that although the NAc encodes associations between neutral stimuli in Preconditioning, and processes information about FOC, SPC expression is not encoded by the NAc core.

Self-excitation of surface plasmon polaritons
Creators: name: Bordo, V. G.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: The novel effect of self-excitation of surface plasmons (SESP) in a plasmonic nanocavity is predicted and its theory is developed from first principles. It is assumed that the cavity is formed by a nanogap between two metals and contains polarizable inclusions. Basing on the dyadic Green's function of the structure, the equations for the field in the cavity are investigated. It is shown that under certain conditions the field becomes unstable that leads to its self-excitation. The threshold criterion for self-excitation as well as the frequency of self-oscillation are derived in an analytical form. The SESP effect is explained in terms of a positive feedback for the polarization of inclusions provided by the field reflected from the cavity walls. Such a mechanism does not imply stimulated emission that distinguishes it from SPASER or plasmon laser.

Association between negative affectivity and craving in substance-related disorders : A systematic review and meta-analysis of direct and indirect relationships.
Creators: name: Cyr, Laura
Publisher: name: Open Science Framework
Year: 2022
Subjects: subject: Psychiatry and Psychology
subject: Medicine and Health Sciences

description: A sizeable litterature highlighted strong links between affectivity and addictive behaviors and supported the relationship between negative affect and craving. Following negative reinforcement and affect-regulation models of addiction, negative affect and craving are both know to be implicated in relapses and to interfere with interventions outcomes. The way in which variables interract and the moderators which plays an important role have been understudied in withdrawal-based craving. This systematic review and meta-analysis integrates mainly findings from observational and experimental data that investigate the association between negative affects (as a trait or state) and craving for several substance use disorders. A comprehensive search from all available researches on the topic was performed in three electronic bibliographic databases (PubMed, PsycINFO, Web of science). From 2538 retrieved articles, 30 fulfilled inclusion criteria and formed the base of the systematic review and 14 studies were included in the meta-analysis. Most of studies (77%, 23/30) were rating as « fair » quality with the NHLBI Risk of Bias tool. Overall, results gave a timely update of the relationship between negative affectivity and craving covering twenty-four years of research. In total, approximately 90% of the studies selected revealed a positive correlation between these variables. Alcohol and tobacco use disorders have received the most attention. Additionally, negative affectivity was often defined as a transient state rather than a stable personality trait. The originality and the richness of this review came from its focus on internal cues and individual differences in negative affective cues; some facets of negative affectivity may relate more strongly to craving than others. We concluded that more rigorous and theorically informed research is needed to clarify the link between negative affectivity as a trait and craving. Longitudinal analyzes were missing, therefore causal link couldn’t be defining. A model of self-regulation and emotional regulation currently associated with substance use disorders should be proposed to understand more craving for cocaine.
The Effect of PRI Repositioning Technique on Innominate Rotation and Hip Range of Motion

Year: 2018

description: Positional malalignment of the sacroiliac joint is a proposed mechanism of non-specific low back pain and a risk factor for lower extremity injury due to theoretical effects on hip range of motion. The Postural Restoration Institute™ (PRI) has introduced novel techniques for assessment and correction of these positional malalignments. Twenty-four subjects displaying a left anterior innominate rotation, as defined by the PRI, participated in two data collection sessions: a control session and an intervention session, where each subject completed a three-exercise pelvic repositioning series. Sagittal and transverse innominate rotation, measured by palpation-digitization, and hip range of motion were collected at three time-points in each session: before intervention, after intervention, and after walking one half-mile. Two-way repeated measures ANOVAs were used to examine interaction of session and time-point. A significant interaction (p = .000) between session and time-point was seen in left adduction range of motion and left total arc frontal plane range of motion. No interaction was observed in the sagittal or transverse innominate rotation angles. This finding supports the PRI’s claim that left adduction range of motion can be increased through use of their repositioning series and provides support for clinical use of this technique in the treatment of hip and low back pain.

description: Models for recommender systems use latent factors to explain the preferences and behaviors of users with respect to a set of items (e.g., movies, books, academic papers). Typically, the latent factors are assumed to be static and, given these factors, the observed preferences and behaviors of users are assumed to be generated without order. These assumptions limit the explorative and predictive capabilities of such models, since users' interests and item popularity may evolve over time. To address this, we propose dPF, a dynamic matrix factorization model based on the recent Poisson factorization model for recommendations. dPF models the time evolving latent factors with a Kalman filter and the actions with Poisson distributions. We derive a scalable variational inference algorithm to infer the latent factors. Finally, we demonstrate dPF on 10 years of user click data from arXiv.org, one of the largest repository of scientific papers and a formidable source of information about the behavior of scientists. Empirically we show performance improvement over both static and, more recently proposed, dynamic recommendation models. We also provide a thorough exploration of the inferred posteriors over the latent variables.

Escapes in Hamiltonian systems with multiple exit channels: Part II

Year: 2015
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: We explore the escape dynamics in open Hamiltonian systems with multiple channels of escape continuing the work initiated in Part I. A thorough numerical investigation is conducted distinguishing between trapped (ordered and chaotic) and escaping orbits. The determination of the location of the basins of escape towards the different escape channels and their correlations with the corresponding escape periods of the orbits is undoubtedly an issue of paramount importance. We consider four different cases depending on the perturbation function which controls the number of escape channels on the configuration space. In every case, we computed extensive samples of orbits in both the configuration and the phase space by numerically integrating the equations of motion as well as the variational equations. It was found that in all examined cases regions of non-escaping motion coexist with several basins of escape. The larger escape periods have been measured for orbits with initial conditions in the vicinity of the fractal structure, while the lowest escape rates belong to orbits with initial conditions inside the basins of escape. In addition, we related the model potential with applications in the field of reactive multichannel scattering. We hope that our numerical analysis will be useful for a further understanding of the escape mechanism of orbits in open Hamiltonian systems with two degrees of freedom.

Reconstructing social shifts through monumental architecture: a Maya palace-temple case from Kiuic, Yucatan, Mexico
Creators: name: Gallareta Cervera, Tomás
Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: Due to their hybrid nature, people and objects cannot be analyzed as separated entities; the changes in one entity are necessarily reflected in the other. Monumental architecture, an object constructed to last a long time in a defined space, becomes a receptacle of accumulated meaning, memory and the social identity of communities interacting with it in their daily life. By reconstructing the social biography of a Maya palace-temple, trough the building's recovered architectonic sequence and its general characteristics, I explore the possible social implications in the life of ancient Maya dwellers though this structure's 1800 years construction history.

description: The known FU Ori-type young eruptive stars are exceedingly rare (a dozen or so confirmed objects) and 2MASS J06593158-0405277, with its 2014 outburst, is likely the latest addition to the family. All members have displayed just one such eruption in their recorded history, an event lasting for decades. To test the FU Ori nature of 2MASS J06593158-0405277, we have reconstructed its photometric history by measuring its brightness on Harvard photographic plates spanning the time interval 1899-1989. No previous large amplitude eruption similar to that initiated in 2014 has been found, as in bona fide FU Ori-type objects. The median value of the brightness in quiescence of 2MASS J06593158-0405277 is B=15.5, with the time interval 1935-1950 characterized by a large variability (~1 mag amplitude) that contrasts with the remarkable photometric stability displayed at later epochs. The variability during 1935-1950 can either be ascribed to some T Tau like activity of 2MASS J06593158-0405277 itself or to the also young and fainter star 2MASS J06593168-0405224 that lies 5 arcsec to the north and forms an unresolved pair at the astrometric scale of Harvard photographic plates.

description: Malnutrition in CKD patients is quite common. Poor nutritional status negatively influences postoperative outcomes of general surgical procedures in CKD patients. Perioperative nutrition intervention could be of great importance. However, literature on this topic appears to be very scarce. Therefore, main objective of this study will be to explore and summarize current knowledge on perioperative nutrition intervention in CKD patients. In this way, knowledge gaps can be identified, which may lead to further research in this field, eventually contributing to an evidence based guideline.

description: Using Blue Horizontal Branch stars identified in the Dark Energy Survey Year 1 data, we report the detection of an extended and lumpy stellar debris distribution around the Magellanic Clouds. At the heliocentric distance of the Clouds, overdensities of BHBs are seen to reach at least to ~30 degrees, and perhaps as far as ~50 degrees from the LMC. In 3D, the stellar halo is traceable to between 25 and 50 kpc from the LMC. We catalogue the most significant of the stellar sub-structures revealed, and announce the discovery of a number of narrow streams and diffuse debris clouds. Two narrow streams appear approximately aligned with the Magellanic Clouds' proper motion. Moreover, one of these overlaps with the gaseous Magellanic Stream on the sky. Curiously, two diffuse BHB agglomerations seem coincident with several of the recently discovered DES satellites. Given the enormous size and the conspicuous lumpiness of the LMC's stellar halo, we speculate that the dwarf could easily have been more massive than previously had been assumed.

description: GENUS OLIVA BRUGUIÈRE, 1789 (1)
Type species: Voluta oliva Linnaeus, 1758; subsequent monotypy by Lamarck, 1799.
Remarks: The genus Oliva is rather heterogeneous and a number of subgenera have been proposed, some of them even raised to full genus (Petuch & Myers, 2014). Petuch & Sargent (1986) recognized 19 subgenera, of which five were monotypic. Tursch & Greifeneder (2001) discussed briefly their status but abstained from the use of subgenera, since in many cases they did not find clear conchological distinctions between them. On the contrary, Hunon et al. (2009) used as valid most of the subgenera that had been proposed earlier, while still leaving some species in Oliva (e.g. O. lacanientai Greifeneder & Blöcher, 1985). Our COI molecular analysis demonstrates that at least some of the subgenera in their current usage are paraphyletic (Fig. 2 – abbreviated subgenera indicated in bold after species names). Nevertheless, we foresee that, with increased taxon sampling in molecular phylogenies, a number of (sub)genera will be found to be justified. However, with the molecular data currently available, we simply list in the following the accepted subgenera, but abstain from using them.
The species delimitation approach would suggest that O. sericea and O. miniacea would be a single species. However, because they are represented by a single specimen each in our analysis and because the two species are distinct conchologically, we remained conservative and did not change the status of the species. Furthermore, Oliva ‘ lacanientai ’ shows great intraspecific variability and probably represents the species complex. We abstained from description of new species, since the species level taxonomy was beyond the scope of the current paper.

Genre and Rhetoric in the Reception of Virgil's Georgics: Poliziano's Rusticus as Didaxis and Epideixis
Creators: name: Wimperis, Tedd Alexander
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: In this thesis I examine the generic and rhetorical underpinnings of Angelo Poliziano's Latin hexameter poem Rusticus (1483), an imitative introduction to agrarian didactic poetry that takes Virgil's Georgics as its primary source. To provide an account of how Poliziano utilizes his classical influences and their generic attributes in this work, I present in the first chapter a brief survey of the author's life and scholarship to establish context, and proceed, in the second chapter, with a close reading of the poem itself, paying special attention to its use of Greek and Latin models. In the third chapter I argue that to facilitate his exposition of agrarian didactic, Poliziano turns to conventions of epideictic rhetoric, and thus introduces the genre by combining its defining features into an epideixis of the rustic life. In the last chapter, I explore the generic admixture of bucolic and didactic elements that pervades the poem, analyzing its tradition in Virgil and later Roman literature, as well as its role in Poliziano's epideixis.

description: We compare the mass and internal distribution of atomic hydrogen (HI) in 2200 present-day central galaxies with M_star > 10^10 M_Sun from the 100 Mpc EAGLE Reference simulation to observational data. Atomic hydrogen fractions are corrected for self-shielding using a fitting formula from radiative transfer simulations and for the presence of molecular hydrogen using an empirical or a theoretical prescription from the literature. The resulting neutral hydrogen fractions, M_(HI+H2)/M_star, agree with observations to better than 0.1 dex for galaxies with M_star between 10^10 and 10^11 M_Sun. Our fiducial, empirical H2 model based on gas pressure results in galactic HI mass fractions, M_HI/M_star, that agree with observations from the GASS survey to better than 0.3 dex, but the alternative theoretical H2 formula leads to a negative offset in M_HI/M_star of up to 0.5 dex. Visual inspection reveals that most HI disks in simulated HI-rich galaxies are vertically disturbed, plausibly due to recent accretion events. Many galaxies (up to 80 per cent) contain spuriously large HI holes, which are likely formed as a consequence of the feedback implementation in EAGLE. The HI mass-size relation of all simulated galaxies is close to (but 16 per cent steeper than) observed, and when only galaxies without large holes in the HI disc are considered, the agreement becomes excellent (better than 0.1 dex). The presence of large HI holes also makes the radial HI surface density profiles somewhat too low in the centre, at Σ_HI > 1 M_Sun pc^-2 (by a factor of 10^9.8 M_Sun) and control galaxies (10^9.1 M_Sun > M_HI > 10^9.8 M_Sun) follow each other closely, as observed.
