description: We introduce a computational method developed for study of long-range molecular Rydberg states of such systems that can be approximated by two electrons in a model potential of the atomic cores. Only diatomic molecules are considered. The method is based on a two-electron \rmath approach inside a sphere centered on one of the atoms. The wave function is then connected to a Coulomb region outside the sphere via multichannel version of the Coulomb Green's function. This approach is put into a test by its application to a study of Rydberg states of the hydrogen molecule for internuclear distances $R$ from 20 to 400 bohrs and energies corresponding to $n$ from 3 to 22. The results are compared with previous quantum chemical calculations (lower quantum numbers $n$) and computations based on contact potential models (higher quantum numbers $n$).

description: The current study is part of a larger project with the aim to investigate reward processing and pupillary responses in MDD. The current sample is a control group, where participants have no current MDD symptoms, but approximately one third has an history of MDD-episodes. We aim to investigate if there are any differences in reward learning and pupillary responses in a shifting reward learning task with two contingencies, one showing at face (happy/sad) as feedback and one showing a thumb (up/down) as feedback.
Emotion Language Acquisition in Young Children

description: Young children gradually acquire the ability to label emotions with words; yet how children understand and develop emotion language is an under researched area. According to linguistic research, syntactical bootstrapping is a prominent factor in a child’s concept learning. While, research in emotion development suggests that children use physical context to guide the learning of emotion concepts. The present studies built off of this literature to examine the role of both syntax and context in children’s (aged 3-5) ability to understand that a novel word refers to an emotion category. In Study 1, (N=120) children watched videos of puppets presenting a novel ‘alien’ word in one of three syntactical structures (is, feels and feels about). After the video, children completed an image selection task in which they could choose one of three images, either a state of being (e.g., cold), an action (e.g., running) or an emotion (e.g., surprised) to indicate what the alien word meant. In Study 2, (N=113) context was included in conjunction with the different syntactical structures. Children watched 7 videos in which an alien portrayed an emotional scenario. After each video the child completed the same image selection task as in Study 1. Across studies, we found that that emotion images are chosen more consistently with age, syntactic structure, and that physical context increases emotion choices.

description: We present a complete characterization of the fluctuations and correlations of the squared overlap in the Edwards-Anderson Spin-Glass model in zero field. The analysis reveals that the energy-energy correlations (and thus the specific heat) have a different critical behavior than the fluctuations of the link overlap in spite of the fact that the average energy and average link overlap have the same critical properties. More precisely the link-overlap fluctuations are larger than the specific heat according to a computation at first order in the $6-ε$ expansion. An unexpected outcome is that the link-overlap fluctuations have a subdominant power-law contribution characterized by an anomalous logarithmic prefactor which is missing in the specific heat. In order to compute the $ε$ expansion we consider the problem of the renormalization of quadratic composite operators in a generic multicomponent cubic field theory: the results obtained have a range of applicability beyond spin-glass theory.

description: The simplest two-field completion of natural inflation has a regime in which both fields are active and in which its predictions are within the Planck 1-$σ$ confidence contour. We show this for the original model of natural inflation, in which inflation is achieved through the explicit breaking of a U(1) symmetry. We consider the case in which the mass coming from explicit breaking of this symmetry is comparable to that from spontaneous breaking, which we show is consistent with a hierarchy between the corresponding energy scales. While both masses are comparable when the observable modes left the horizon, the mass hierarchy is restored in the last e-foldings of inflation, rendering the predictions consistent with the isocurvature bounds. For completeness, we also study the predictions for the case in which there is a large hierarchy of masses and an initial period of inflation driven by the (heavy) radial field.

description: We propose two strategies to improve the quality of tractography results computed from diffusion weighted magnetic resonance imaging (DW-MRI) data. Both methods are based on the same PDE framework, defined in the coupled space of positions and orientations, associated with a stochastic process describing the enhancement of elongated structures while preserving crossing structures. In the first method we use the enhancement PDE for contextual regularization of a fiber orientation distribution (FOD) that is obtained on individual voxels from high angular resolution diffusion imaging (HARDI) data via constrained spherical deconvolution (CSD). Thereby we improve the FOD as input for subsequent tractography. Secondly, we introduce the fiber to bundle coherence (FBC), a measure for quantification of fiber alignment. The FBC is computed from a tractography result using the same PDE framework and provides a criterion for removing the spurious fibers. We validate the proposed combination of CSD and enhancement on phantom data and on human data, acquired with different scanning protocols. On the phantom data we find that PDE enhancements improve both local metrics and global metrics of tractography results, compared to CSD without enhancements. On the human data we show that the enhancements allow for a better reconstruction of crossing fiber bundles and they reduce the variability of the tractography output with respect to the acquisition parameters. Finally, we show that both the enhancement of the FODs and the use of the FBC measure on the tractography improve the stability with respect to different stochastic realizations of probabilistic tractography. This is shown in a clinical application: the reconstruction of the optic radiation for epilepsy surgery planning.

description: In recent years several small basaltic V-type asteroids have been identified all around the main belt. Most of them are members of the Vesta dynamical family, but an increasingly large number appear to have no link with it. The question that arises is whether all these basaltic objects do indeed come from Vesta. To find the answer to the above questioning, we decided to perform a statistical analysis of the spectroscopic and mineralogical properties of a large sample of V-types, with the objective to highlight similarities and differences among them, and shed light on their unique, or not, origin. The analysis was performed using 190 visible and near-infrared spectra from the literature for 117 V-type asteroids. The asteroids were grouped according to their dynamical properties and their computed spectral parameters compared. Comparison was also performed with spectral parameters of a sample of HED meteorites and data of the surface of Vesta taken by the VIR instrument on board of the Dawn spacecraft. Our analysis shows that although most of the V-type asteroids in the inner main belt do have a surface composition compatible with an origin from Vesta, this seem not to be the case for V-types in the middle and outer main belt.

Year: 2019

description: Mobile health (mHealth) applications have been on the rise as technology continues to advance. These apps have the potential to address several barriers to accessing care for mental health concerns in the African American community. This study examined associations between mental health symptoms, racial discrimination, racial identity, attitudes regarding mental health treatment, and perceptions of mHealth treatment in 38 African American young adults (mean age = 20.7, s.d., = 2.6). Online vicarious racial discrimination was related to mental health treatment attitudes and perceptions of culturally-adapted mobile health apps for African Americans. Racial identity was related to positive mental health treatment attitudes and perceptions of mHealth appropriateness and a culturally-adapted mHealth app. These findings suggest that cultivating positive racial identity attitudes may help to address mental health treatment seeking and the use of culturally-adapted mHealth interventions for African American young adults.

description: Trigger warnings alert trauma survivors about potentially disturbing forthcoming content. However, empirical studies on trigger warnings suggest that they are functionally inert or cause small adverse side effects. We conducted a preregistered replication and extension of a previous experiment. Trauma survivors (n = 451) were randomly assigned to either receive or not receive trigger warnings prior to reading passages from world literature. We found no evidence that trigger warnings were helpful for trauma survivors, for those who self-reported a PTSD diagnosis, or for those who qualified for probable PTSD, even when survivors' trauma matched the passages' content. We found substantial evidence that trigger warnings countertherapeutically reinforce survivors' view of their trauma as central to their identity. Regarding replication hypotheses, the evidence was either ambiguous or substantially favored the hypothesis that trigger warnings have no effect. In summary, we find that trigger warnings are not helpful for trauma survivors.

description: We determined 40Ar/39Ar ages of buddingtonite, occurring together with muscovite, with the laser-ablation method. This is the first attempt to date the NH4-feldspar buddingtonite, which is typical for sedimentary–diagenetic environments of sediments, rich in organic matter, or in hydrothermal environments, associated with volcanic geyser systems. The sample is a hydrothermal breccia, coming from the Paleoproterozoic pegmatite field of the Korosten Plutonic Complex, Volyn, Ukraine. A detailed characterization by optical methods, electron microprobe analyses, backscattered electron imaging, and IR analyses showed that the buddingtonite consists of euhedral-appearing platy crystals of tens of micrometers wide, 100 or more micrometers in length, which consist of fine-grained fibers of ≤ 1 µm thickness. The crystals are sector and growth zoned in terms of K–NH4–H3O content. The content of K allows for an age determination with the 40Ar/39Ar method, as well as in the accompanying muscovite, intimately intergrown with the buddingtonite. The determinations on muscovite yielded an age of 1491 ± 9 Ma, interpreted as the hydrothermal event forming the breccia. However, buddingtonite apparent ages yielded a range of 563 ± 14 Ma down to 383 ± 12 Ma, which are interpreted as reset ages due to Ar loss of the fibrous buddingtonite crystals during later heating. We conclude that buddingtonite is suited for 40Ar/39Ar age determinations as a supplementary method, together with other methods and minerals; however, it requires a detailed mineralogical characterization, and the ages will likely represent minimum ages.

description: Cellwise outliers are likely to occur together with casewise outliers in modern data sets with relatively large dimension. Recent work has shown that traditional robust regression methods may fail for data sets in this paradigm. The proposed method, called three-step regression, proceeds as follows: first, it uses a consistent univariate filter to detect and eliminate extreme cellwise outliers; second, it applies a robust estimator of multivariate location and scatter to the filtered data to down-weight casewise outliers; third, it computes robust regression coefficients from the estimates obtained in the second step. The three-step estimator is shown to be consistent and asymptotically normal at the central model under some assumptions on the tail distributions of the continuous covariates. The estimator is extended to handle both numerical and dummy covariates using an iterative algorithm. Extensive simulation results show that the three-step estimator is resilient to cellwise outliers. It also performs well under casewise contaminations when comparing with traditional high breakdown point estimators.

description: We study the BCS-Bose Einstein Condensation (BEC) crossover of a three dimensional spin polarized Fermi gas with Rashba spin-orbital-coupling (SOC). At finite temperature, the effects of non-condensed pairs due to the thermal excitation are considered based on the $G_0G$ pair fluctuation theory. These fluctuations generate a pseudogap even persistent above $T_c$. Within this framework, the Sarma state or the spin polarized superfluid state and polarized pseudogap state are explored in detail. The resulting $T_c$ curves show that the enhancement of pairing due to the SOC roughly cancels out the suppression of pairing due to the population imbalance. Thus we observed that in a large portion of the parameter space, the polarized superfluid state are stabilized by the SOC.

description: In this thesis, I examine the three dominant literary influences on Petronius' Satyricon and argue that his engagement with them is not merely literary play but instead a cohesive statement about the purpose of education under Nero.

description: We present a continuous formulation of epidemic spreading on multilayer networks using a tensorial representation, extending the models of monoplex networks to this context. We derive analytical expressions for the epidemic threshold of the SIS and SIR dynamics, as well as upper and lower bounds for the disease prevalence in the steady state for the SIS scenario. Using the quasi-stationary state method we numerically show the existence of disease localization and the emergence of two or more susceptibility peaks, which are characterized analytically and numerically through the inverse participation ratio. Furthermore, when mapping the critical dynamics to an eigenvalue problem, we observe a characteristic transition in the eigenvalue spectra of the supra-contact tensor as a function of the ratio of two spreading rates: if the rate at which the disease spreads within a layer is comparable to the spreading rate across layers, the individual spectra of each layer merge with the coupling between layers. Finally, we verified the barrier effect, i.e., for three-layer configuration, when the layer with the largest eigenvalue is located at the center of the line, it can effectively act as a barrier to the disease. The formalism introduced here provides a unifying mathematical approach to disease contagion in multiplex systems opening new possibilities for the study of spreading processes.

description: Evapotranspiration (ET) is a fundamental variable for assessing water balance and the urban heat island (UHI) effect. Terrestrial ET is deeply dependent on the land cover as it derives mainly from soil evaporation and plant transpiration. The majority of well-known process-based models based on the Penman–Monteith equation focus on the atmospheric interfaces (e.g. radiation, temperature and humidity), lacking explicit input parameters to precisely describe vegetation and soil properties. The model soil-canopy-observation of photosynthesis and energy fluxes (SCOPE) accounts for a broad range of surface–atmosphere interactions to predict ET. However, like most modelling approaches, SCOPE assumes a homogeneous vegetated landscape to estimate ET. As urban environments are highly fragmented, exhibiting a mix of vegetated and impervious surfaces, we propose a two-stage modelling approach to capture most of the spatiotemporal variability of ET without making the model overly complex. After predicting ET using the SCOPE model, the bias caused by the assumption of homogeneous vegetation is corrected using the vegetation fraction extracted by footprint modelling. Two urban sites equipped with eddy flux towers presenting different levels of vegetation fraction and imperviousness located in Berlin, Germany, were used as study cases. The correction factor for urban environments increased the model accuracy significantly, reducing the relative bias in ET predictions from 0.74 to 0.001 and 2.20 to −0.13 for the two sites considering the SCOPE model with remote sensing-derived inputs. Model errors (RMSE) were considerably reduced in both sites, from 0.061 to 0.026 and 0.100 to 0.021, while the coefficient of determination (R2) remained similar after correction, 0.82 and 0.47, respectively. The novelty of this study is to provide hourly ET predictions combining the temporal dynamics of ET in a natural environment with the spatially fragmented land cover in urban environments at a low computational cost. All model inputs are open data and available globally for most medium-sized and large cities. This approach can provide ET maps in different temporal resolutions to better manage vegetation in cities in order to mitigate the UHI effect and droughts.
The Sr Budget in the Croatan National Forest

description: Samples of surface waters (lakes and rivers), precipitation, surficial well water, and vegetation were collected from the region of the Croatan National Forest of North Carolina. Using mass spectrometry, Sr concentrations and 87Sr/ 86Sr ratios were calculated. Precipitation samples have 87Sr/86Sr ratios ranging from 0.708738 ± 0.00001 – 0.710630 ± 0.00001. The average 87Sr/86Sr ratio for precipitation samples is 0.709364. The 87Sr/86Sr ratios for surface water samples are widely variable, with a range of 0.708611 ± 0.00001 - 0.710859 ± 0.00001. Rivers and lakes in the Croatan National Forest that have not mixed with the Neuse River or Trent River have 87Sr/86Sr ratios higher than modern seawater and precipitation, indicating that when precipitation falls in the forest it mixes with a source of high 87Sr/86Sr ratios relative to seawater. The Neuse River, Trent River, and surface waters that mix with the Neuse and Trent Rivers have 87Sr/86Sr ratios within error of modern seawater. Samples from the White Oak River and the western Trent River have 87Sr/86Sr ratios within the range of 87Sr/86Sr ratios predicted on 87Sr/86Sr seawater curves for formations that are late Eocene to early Miocene in age. Samples from surficial wells have 87Sr/86Sr ratios of 0.709687 ± 0.00001 and 0.709415 ± 0.00001, within the range of surface water samples and higher than modern seawater (0.70918). We conclude that an undetermined source with high 87Sr/86Sr ratios is interacting with the Croatan National Forest region, and we hypothesize that this source may be atmospheric dust or upwelling of deep groundwater that has come in contact with basement rocks.

description: Extrasolar planets that pass in front of their host star (transit) cause a temporary decrease in the apparent brightness of the star once per orbit, providing a direct measure of the planet's size and orbital period. In some systems with multiple transiting planets, the times of the transits are measurably affected by the gravitational interactions between neighbouring planets. In favorable cases, the departures from Keplerian orbits implied by the observed transit times permit planetary masses to be measured, which is key to determining bulk densities. Characterizing rocky planets is particularly difficult, since they are generally smaller and less massive than gaseous planets. Thus, few exoplanets near Earth's size have had their masses measured. Here we report the sizes and masses of three planets orbiting Kepler-138, a star much fainter and cooler than the Sun. We measure the mass of the Mars-sized inner planet based on on the transit times of its neighbour and thereby provide the first density measurement for an exoplanet smaller than Earth. The middle and outer planets are both slightly larger than Earth. The middle planet's density is similar to that of Earth, while the outer planet is less than half as dense, implying that it contains a greater portion of low density components such as H2O and/or H2.
Polysubstance Use Associated with Lower Distress Tolerance Compared to Single-Substance Use
Creators: name: Jones, Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Polysubstance users face a number of severe outcomes in comparison to single-substance users. In line with negative reinforcement theory, it has been postulated that polysubstance use occurs as a result of the desire to avoid unwanted effects that come from using either a stimulant or depressant alone. The current study examined a proxy for negative reinforcement behavior, distress tolerance (DT), among single-substance and depressant-stimulant polysubstance users. DT is defined as the ability to persist in a goal-directed behavior while experiencing psychological distress. Polysubstance users were hypothesized to have lower DT compared to those who used only one substance. One hundred seventy six (n = 176) participants were recruited through a residential treatment center, where they completed a battery of self-report measures and a distress tolerance task. Results from a logistic regression showed that individuals with low DT were 2.4 times more likely to be a polysubstance user compared to those with high DT. These results suggest depressant-stimulant polysubstance users have a lower ability to tolerate psychological distress in comparison to single-substance users. This is the first study to examine distress tolerance and polysubstance use, and results may have important clinical implications in the treatment of addiction.

description: We consider a hydrogen atom confined in a thick brane embedded in a higher-dimensional space. Due to effects of the extra dimensions, the gravitational potential is amplified in distances smaller than the size of the supplementary space, in comparison with the Newtonian potential. Studying the influence of the gravitational interaction modified by the extra dimensions on the energy levels of the hydrogen atom, we find independent constraints for the higher-dimensional Planck mass in terms of the thickness of the brane by using accurate measurements of atomic transition frequencies. The constraints are very stringent for narrow branes.

This study is designed to analyze the essential oils of two Iranian Thymus species, (T. kotschyanus Boiss. et Hohen and T. pubescense Boiss. et Kotschy ex Celak) obtained by hydrodistillation of aerial part of this plants, using GC-FID and GC/MS and evaluate the in-vitro antioxidant activities in two quantitative methods (namely DPPH. and ABTS.+ assay) to determine the total phenolic content of the species (assayed by colorimetric techniques) and to study the possible compositionantioxidant activity relationship. The major aroma constitutes in the essential oil of T. pubescense were found to be thymol (38.7 %), γ-terpinene (7.5 %), p-cymene (5.5 %), α-terpenyl acetate (3.8 %) and β-bisabolene (3.7 %) while in the essential oil of T. kotschyanus, -terpineol (16.9 %), 1,8-cineol (14.4 %), linalool (9.6 %), thymol (7.2 %) and geranyl acetate (5.4 %) were the main compounds. Both of the tested essential oils exhibited concentration-dependent antioxidant activity. T. pubescense showed more activity in both DPPH. [IC50= 285.2 (236.5-344.0) μg/mL] and ABTS.+ methods [IC50= 1.956 (1.810-2.113) μg/mL], as well as total phenolic content of T. pubescence [70254 ± 0.0049 μg/mg] was found to be slightly higher than T. kotschyanus [62933 ± 0.0026 μg/mg].

description: We review the literature relating to soft skills and the software engineering and information systems domain before describing a study based on 650 job advertisements posted on well-known recruitment sites from a range of geographical locations including, North America, Europe, Asia and Australia. The study makes use of nine defined soft skills to assess the level of demand for each of these skills related to individual job roles within the software industry. This work reports some of the vital statistics from industry about the requirements of soft skills in various roles of software development phases. The work also highlights the variation in the types of skills required for each of the roles. We found that currently although the software industry is paying attention to soft skills up to some extent while hiring but there is a need to further acknowledge the role of these skills in software development. The objective of this paper is to analyze the software industry soft skills requirements for various software development positions, such as system analyst, designer, programmer, and tester. We pose two research questions, namely, (1) What soft skills are appropriate to different software development lifecycle roles, and (2) Up to what extend does the software industry consider soft skills when hiring an employee. The study suggests that there is a further need of acknowledgment of the significance of soft skills from employers in software industry.

description: Coupling light to Rydberg states of atoms under conditions of electromagnetically induced transparency (EIT) leads to the formation of strongly interacting quasi-particles, termed Rydberg polaritons. We derive a one-dimensional model describing the time evolution of these polaritons under paraxial propagation conditions, which we verify by numerical two-excitation simulations. We determine conditions allowing for a description by an effective Hamiltonian of a single-species polariton, and calculate ground-state correlations by use of the density matrix renormalization group (DMRG). Under typical stationary slow-light EIT conditions it is difficult to reach the strongly interacting regime where the interaction energy dominates the kinetic energy. We show that by employing time dependence of the control field the regime of strong interactions can be reached where the polaritons attain quasi crystalline order. We analyze the dynamics and resulting correlations for a translational invariant system in terms of a time-dependent Luttinger liquid theory and exact few-particle simulations and address the effects of nonadiabatic corrections and initial excitations.

description: Type III radio bursts are intense radio emissions triggered by beams of energetic electrons often associated with solar flares. These exciter beams propagate outwards from the Sun along an open magnetic field line in the corona and in the interplanetary (IP) medium. We performed a statistical survey of 29 simple and isolated IP type III bursts observed by STEREO/Waves instruments between January 2013 and September 2014. We investigated their time-frequency profiles in order to derive the speed and acceleration of exciter electron beams. We show these beams noticeably decelerate in the IP medium. Obtained speeds range from $\sim$ 0.02c up to $\sim$ 0.35c depending on initial assumptions. It corresponds to electron energies between tens of eV and hundreds of keV, and in order to explain the characteristic energies or speeds of type III electrons ($\sim 0.1$c) observed simultaneously with Langmuir waves at 1 au, the emission of type III bursts near the peak should be predominately at double plasma frequency. Derived properties of electron beams can be used as input parameters for computer simulations of interactions between the beam and the plasma in the IP medium.
A Randomized Trial of the Impact of Amber Versus Blue Glasses  on Sleep Quality, Energy and Mood
Creators: name: Lukacs, Julia N.

description: The connections between sleep and mood disorders have prompted speculation in the
field of psychology for some time. The human circadian rhythm, the biological mechanism
which has a significant impact on the diurnal highs and lows of both wakefulness and mood, is impacted by a variety of endogenous and exogenous factors. One of the most potent of these factors is light, but it has recently been proven that the absence or presence of blue wavelength light (446-477 nm) has a particularly strong effect. With the use of blue light blocking amber lenses, one may be able to influence and regulate sleep, mood and potentially mental health for the better, especially in individuals for whom these cycles are disrupted. In a randomized trial, 27 students at the University of North Carolina at Chapel Hill, aged 18-26, wore either control blue or experimental amber lenses for three hours prior to their own calculated average bedtime for 12 days of an 18 day protocol. Participants completed self-report measures of sleep quality, mood, and somatic complaints on a daily basis, and more precise measures of sleep quality every 6 days. The first 6 days when they did not wear glasses were compared to the later 12 days during which they did wear the blue or amber glasses. There was a
significant improvement in sleep, energy, and mood when participants wore the amber and blue glasses (p < .005), but there was no difference between the two conditions. Future directions could include the use of more objective sleep measures and testing glasses of different colors.
BFO as a top-level ontology for information systems modeling

Subjects: ontology

description: Top-level ontologies are essential for developing domain ontologies underlying intelligent information systems by providing modeling patterns for entities of all kinds. Top-level ontologies can reduce ambiguity and context issues related to the language employed to create knowledge units suitable to knowledge representation systems. Despite its widespread use and importance, information systems and information science researchers and professionals as well, need to learn how to take advantage of top-level ontologies, like the Basic Formal Ontology (BFO). This tutorial explores the essentials of BFO, its entities and relationships in two modules. The first module approaches BFO’s branches traversing top-level entities and revealing the two persistence theories it includes. The second module advances in implementing an ontology example, importing BFO and constructing a small domain ontology downwards. The tutorial is aimed at everyone that wants to learn how to start developing suitable ontologies and incrementing data quality.

description: This article demonstrates the applicability of the parallel-in-time method Parareal to the numerical solution of the Einstein gravity equations for the spherical collapse of a massless scalar field. To account for the shrinking of the spatial domain in time, a tailored load balancing scheme is proposed and compared to load balancing based on number of time steps alone. The performance of Parareal is studied for both the sub-critical and black hole case; our experiments show that Parareal generates substantial speedup and, in the super-critical regime, can reproduce Choptuik's black hole mass scaling law.

description: Magnetic vortex cores exhibit a gyrotropic motion, and may reach a critical velocity, at which point they invert their z-component of the magnetization. We performed micromagnetic simulations to describe this vortex core polarity reversal in magnetic nanodisks presenting a perpendicular anisotropy. We found that the critical velocity decreases with increasing perpendicular anisotropy, therefore departing from a universal criterion, that relates this velocity only to the exchange stiffness of the material. This leads to a critical velocity inversely proportional to the vortex core radius. We have also shown that in a pair of interacting disks, it is possible to switch the core vortex polarity through a non-local excitation; exciting one disk by applying a rotating magnetic field, one is able to switch the polarity of a neighbor disk, with a larger perpendicular anisotropy.
