description: The interaction of ionizing and far-ultraviolet radiation with the interstellar medium is of great importance. It results in the formation of regions in which the gas is ionized, beyond which are photodissociation regions (PDRs) in which the gas transitions to its atomic and molecular form. Several numerical codes have been implemented to study these two main phases of the interstellar medium either dynamically or chemically. In this paper we present TORUS-3DPDR, a new self-consistent code for treating the chemistry of three-dimensional photoionization and photodissociation regions. It is an integrated code coupling the two codes TORUS, a hydrodynamics and Monte Carlo radiation transport code, and 3D-PDR, a photodissociation regions code. The new code uses a Monte Carlo radiative transfer scheme to account for the propagation of the ionizing radiation including the diffusive component as well as a ray-tracing scheme based on the HEALPix package in order to account for the escape probability and column density calculations. Here, we present the numerical techniques we followed and we show the capabilities of the new code in modelling three-dimensional objects including single or multiple sources. We discuss the effects introduced by the diffusive component of the UV field in determining the thermal balance of PDRs as well as the effects introduced by a multiple sources treatment of the radiation field. We find that diffuse radiation can positively contribute to the formation of CO. With this new code, three-dimensional synthetic observations for the major cooling lines are possible, for making feasible a detailed comparison between hydrodynamical simulations and observations.

Measuring style shift: a quantitative analysis of African American English
Creators: name: Renn, Jennifer
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: This investigation considers how African American adolescents shift their speech styles based on context by examining the speech of 50 sixth-graders. It assesses the use of African American English structures in formal and informal peer contexts to determine which features are affected by the situation. The results reveal shifts in the overall inventory of structures, indicating that adolescents have a growing awareness of the role of situational context in adjusting their speech. Analyses also suggest that not all dialect features are implicated in shifting; thus, a revised inventory of features is proposed to quantify style shift. The goal was to arrive at a minimally adequate subset of features that effectively assesses speakers’ overall vernacular use as well as their shifting behavior across contexts. This subset measure is compared to other “all-encompassing” measures and the advantages and disadvantages of both methodologies are discussed.

description: In incremental learning, replaying stored samples from previous tasks together with current task samples is one of the most efficient approaches to address catastrophic forgetting. However, unlike incremental classification, image replay has not been successfully applied to incremental object detection (IOD). In this paper, we identify the overlooked problem of foreground shift as the main reason for this. Foreground shift only occurs when replaying images of previous tasks and refers to the fact that their background might contain foreground objects of the current task. To overcome this problem, a novel and efficient Augmented Box Replay (ABR) method is developed that only stores and replays foreground objects and thereby circumvents the foreground shift problem. In addition, we propose an innovative Attentive RoI Distillation loss that uses spatial attention from region-of-interest (RoI) features to constrain current model to focus on the most important information from old model. ABR significantly reduces forgetting of previous classes while maintaining high plasticity in current classes. Moreover, it considerably reduces the storage requirements when compared to standard image replay. Comprehensive experiments on Pascal-VOC and COCO datasets support the state-of-the-art performance of our model.
Infectious Disease May Represent Intrinsic or Extrinsic Risk in Enacting Slow or Fast Life History Strategy and Related Behavior

Subjects: subject: Social and Behavioral Sciences

description: The COVID-19 pandemic caught the world by surprise and raised many questions. One of the questions is whether infectious diseases indeed drive fast life history (LH) as the extent research suggests. This paper challenges this assumption and raises a different perspective. We argue that infectious diseases are not linearly related with LH strategies, but depending on the severity of the diseases, manifest either as intrinsic or extrinsic risks in enacting either slower or faster LH strategies and the related behavior.

description: We propose and develop a Bayesian plaid model for biclustering that accounts for the prior dependency between genes (and/or conditions) through a stochastic relational graph. This work is motivated by the need for improved understanding of the molecular mechanisms of human diseases for which effective drugs are lacking, and based on the extensive raw data available through gene expression profiling. We model the prior dependency information from biological knowledge gathered from gene ontologies. Our model, the Gibbs-plaid model, assumes that the relational graph is governed by a Gibbs random field. To estimate the posterior distribution of the bicluster membership labels, we develop a stochastic algorithm that is partly based on the Wang-Landau flat-histogram algorithm. We apply our method to a gene expression database created from the study of retinal detachment, with the aim of confirming known or finding novel subnetworks of proteins associated with this disorder.

An Investigation of Flow Rate Motivated Mobilization of Entrapped Organic Liquids in Two-Fluid Phase Porous Medium Systems
Creators: name: Tao, Ranxin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Groundwater is one of the nation’s most important natural resources, composing a large portion of total freshwater on earth. Therefore, groundwater contamination is a growing concern among groundwater hydrologists and the general public. Organic contaminants, often present as non-aqueous phase liquid (NAPL) in the groundwater, are major groundwater contaminants of concern. The purpose of this work was to investigate the mobilization of entrapped disconnected NAPL in porous medium systems. Tetrachloroethylene (PCE) was chosen as a model NAPL compound. Fluid properties of PCE were analyzed and column experiments as well as lattice Boltzmann simulations were performed to determine the relationships between residual NAPL saturation, fluid properties, and viscous forces. Trapping number (NT) was tested as a criterion to predict and validate residual NAPL mobilization in porous media. Residual saturation was found to decrease with increasing viscous forces and NT. The experimental data and simulation results were compared and showed good agreement.

description: The connection between dark matter halos and galactic baryons is often not well-constrained nor well-resolved in cosmological hydrodynamical simulations. Thus, Halo Occupation Distribution (HOD) models that assign galaxies to halos based on halo mass are frequently used to interpret clustering observations, even though it is well-known that the assembly history of dark matter halos is related to their clustering. In this paper we use high-resolution hydrodynamical cosmological simulations to compare the halo and stellar mass growth of galaxies in a large-scale overdensity to those in a large-scale underdensity (on scales of about 20 Mpc). The simulation reproduces assembly bias, that halos have earlier formation times in overdense environments than in underdense regions. We find that the stellar mass to halo mass ratio is larger in overdense regions in central galaxies residing in halos with masses between 10$^{11}$-10$^{12.9}$ M$_{\odot}$. When we force the local density (within 2 Mpc) at z=0 to be the same for galaxies in the large-scale over- and underdensities, we find the same results. We posit that this difference can be explained by a combination of earlier formation times, more interactions at early times with neighbors, and more filaments feeding galaxies in overdense regions. This result puts the standard practice of assigning stellar mass to halos based only on their mass, rather than considering their larger environment, into question.

description: Searching for new non-perturbatively renormalizable quantum gravity theories, functional renormalization group (RG) flows are studied on a theory space of action functionals depending on the metric and the torsion tensor, the latter parameterized by three irreducible component fields. A detailed comparison with Quantum Einstein-Cartan Gravity (QECG), Quantum Einstein Gravity (QEG), and "tetrad-only" gravity, all based on different theory spaces, is performed. It is demonstrated that, over a generic theory space, the construction of a functional RG equation (FRGE) for the effective average action requires the specification of a metric on the infinite-dimensional field manifold as an additional input. A modified FRGE is obtained if this metric is scale-dependent, as it happens in the metric-torsion system considered.

Focus Group Findings to Inform an Educational Program for Nurse Practitioner Entrepreneurs
Creators: name: Ervin, Virginia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Background. The Institute of Medicine’s Future of Nursing Report (2010) recommends that nurses should be major players in the redesign of the current health care system and that higher levels of education for nurses should be one of the goals in the process of transformation. If part of the health care system redesign includes opportunities for nurse practitioner entrepreneurship and business ownership, then education that prepares nurse practitioners for this role is a necessity. Purpose. The purpose of this exploratory project was to gain insight and gather recommendations from nurse practitioners in North Carolina to inform the development of an education program for nurse practitioners interested in owning their own practice. Participants. Volunteers were recruited for two focus group interviews which resulted in a total of nine participants. Participants were nurse practitioners in North Carolina who have an interest in owning their own practice and were willing to share their ideas regarding the development of an educational program aimed at preparing nurse practitioner entrepreneurs. Methods. Focus group interviews were conducted using a face-to-face format and an online format. Transcribed data were coded according to three primary themes of the emancipatory learning theory: marginalization/oppression, disorienting dilemma/critical reflection, and problem-posing. The data were analyzed to answer the questions: (a) how interested are nurse practitioners in business ownership, (b) do nurse practitioners need formal educational programs to teach them how to operate a private practice, and (c) what factors do nurse practitioners consider to be most important in the development of such an educational program? Findings. The data demonstrate that there is an interest in business ownership, there is a need for an educational program for nurse practitioners interested in business ownership and entrepreneurship, and that such a program would most likely be presented as a multiple semesters certificate-type program in the University setting. Preferred courses would include topics such as business planning, marketing, human resources, and management; hands-on learning opportunities should include internships offering a “behind-the-scenes” look at business management. Conclusion. The information gathered serves as a component of the needs assessment process which would be a helpful tool in the development of a functional educational program and/or the development of policies related to educational opportunities to be made available to interested nurse practitioners.

description: X-ray absorption spectroscopy (XAS) and x-ray magnetic circular dichroism (XMCD) have been used to study transition metal impurities on K and Na films. The multiplet structure of the XAS spectra indicates that Fe, Co, and Ni have localized atomic ground states with predominantly d7, d8, and d9 character, respectively. XMCD shows that the localized impurity states possess large, atomiclike, magnetic orbital moments that are progressively quenched as clusters are formed. Ni impurities on Na films are found to be nonmagnetic, with a strongly increased d10 character of the impurity state. The results show that the high magnetic moments of transition metals in alkali hosts originate from electron localization.

description: The second-order hydrodynamical description of a homogeneous conformal plasma that undergoes a boost- invariant expansion is given by a single nonlinear ordinary differential equation, whose resurgent asymptotic properties we study, developing further the recent work of Heller and Spalinski [Phys. Rev. Lett. 115, 072501 (2015)]. Resurgence clearly identifies the non-hydrodynamic modes that are exponentially suppressed at late times, analogous to the quasi-normal-modes in gravitational language, organizing these modes in terms of a trans-series expansion. These modes are analogs of instantons in semi-classical expansions, where the damping rate plays the role of the instanton action. We show that this system displays the generic features of resurgence, with explicit quantitative relations between the fluctuations about different orders of these non-hydrodynamic modes. The imaginary part of the trans-series parameter is identified with the Stokes constant, and the real part with the freedom associated with initial conditions.

description: The Chronic Liver Disease (CLivD) risk score was recently shown to predict future advanced liver disease in the general population. We here investigated the impact of individual CLivD-score changes over time. Participants of both phase 3 (baseline, 1991–1994) and phase 5 (follow-up, 1997–1999) examinations of the Whitehall II study were followed for liver-related outcomes (hospitalization, cancer, death) until December 2019 through linkage with electronic healthcare registers. The CLivD score, its modifiable components (alcohol use, waist–hip ratio [WHR], diabetes, and smoking), and their individual changes were studied. Among 6590 adults (mean age 50 years, 30% women) with a median 21-year follow-up, there were 80 liver outcomes. A rise in the CLivD score between baseline and follow-up examinations significantly increased the risk for liver-related outcomes (adjusted hazard ratio [aHR] 1.62, 95% confidence interval [CI] 1.01–2.60), more so in subjects with baseline intermediate–high CLivD scores (HR 2.4 for a CLivD-change) compared to minimal-low CLivD scores. Adverse changes over time in alcohol use and WHR, and new-onset diabetes also predicted liver outcomes. In contrast to WHR, changes in body weight (kg) showed a U-shaped association with liver outcomes. A change in the CLivD score over time corresponds to a true change in the risk for liver-related outcomes, suggesting the usefulness of the CLivD score for assessing response to liver-directed lifestyle interventions. Changes in WHR predicted liver outcomes better than changes in body weight or waist circumference, independent of body mass index, supporting the WHR in assessing risk for future liver disease.

description: The origin of the stellar initial mass function (IMF) is a fundamental issue in the theory of star formation. It is generally fit with a composite power law. Some clues on the progenitors can be found in dense starless cores that have a core mass function (CMF) with a similar shape. In the low-mass end, these mass functions increase with mass, albeit the sample may be somewhat incomplete; in the high-mass end, the mass functions decrease with mass. There is an offset in the turn-over mass between the two mass distributions. The stellar mass for the IMF peak is lower than the corresponding core mass for the CMF peak in the Pipe Nebula by about a factor of three. Smaller offsets are found between the IMF and the CMFs in other nebulae. We suggest that the offset is likely induced during a starburst episode of global star formation which is triggered by the formation of a few O/B stars in the multi-phase media, which naturally emerged through the onset of thermal instability in the cloud-core formation process. We consider the scenario that the ignition of a few massive stars photoionizes the warm medium between the cores, increases the external pressure, reduces their Bonnor?Ebert mass, and triggers the collapse of some previously stable cores. We quantitatively reproduce the IMF in the low-mass end with the assumption of additional rotational fragmentation.

User behavior learning

description: In typical restaurant recommendations, knowledge-based methods are used most often and do not take advantage of personal historical data. In this thesis, we are going to make some improvements to the Chicago Entrée restaurant recommender system. We will exploit the historical data and propose a weighted similarity approach to combine heuristic similarity with tag similarity between restaurants. Also, we show an improved way to mine the semantics of user behaviors using heuristic metric. These proposed approaches are evaluated by the comparison of three different pairwise approaches to learning to rank (LTR) in matrix factorization and five classic recommendation algorithms. The result shows that the combinatorial similarity outperforms the heuristic similarity on the precision, recall, F-score, and mean reciprocal rank.
A Taxonomy for Requirements Engineering and Software Test Alignment

description: Requirements Engineering and Software Testing are mature areas and have seen a lot of research. Nevertheless, their interactions have been sparsely explored beyond the concept of traceability. To fill this gap, we propose a definition of requirements engineering and software test (REST) alignment, a taxonomy that characterizes the methods linking the respective areas, and a process to assess alignment. The taxonomy can support researchers to identify new opportunities for investigation, as well as practitioners to compare alignment methods and evaluate alignment, or lack thereof. We constructed the REST taxonomy by analyzing alignment methods published in literature, iteratively validating the emerging dimensions. The resulting concept of an information dyad characterizes the exchange of information required for any alignment to take place. We demonstrate use of the taxonomy by applying it on five in-depth cases and illustrate angles of analysis on a set of thirteen alignment methods. In addition, we developed an assessment framework (REST-bench), applied it in an industrial assessment, and showed that it, with a low effort, can identify opportunities to improve REST alignment. Although we expect that the taxonomy can be further refined, we believe that the information dyad is a valid and useful construct to understand alignment.

description: Studies have shown that females are more likely to suffer non-contact anterior cruciate ligament injuries than males. The study consisted of eleven gymnastics, fifteen lacrosse, and twelve soccer athletes with no history of major lower extremity or anterior cruciate ligament injury one month prior to testing. Lower extremity kinematics, kinetics, and vertical ground reaction forces were collected from the dominant leg of each subject. Joint angles at initial ground contact for female gymnasts were significantly less than soccer athletes for knee and hip flexion. Gymnasts displayed significantly larger knee extension moments, hip flexion moments, anterior tibial shear forces, and vertical ground reaction forces. Female gymnastics athletes performed jump-landing and cutting maneuvers in such a way that may predispose them to anterior cruciate ligament injury. Our results suggest that further investigation is needed into differences in movement patterns and injury rates between female athletes to determine which athletes are at greater risk for injuring the anterior cruciate ligament.

description: Weak alignment of requirements engineering (RE) with verification and validation (VV) may lead to problems in delivering the required products in time with the right quality. For example, weak communication of requirements changes to testers may result in lack of verification of new requirements and incorrect verification of old invalid requirements, leading to software quality problems, wasted effort and delays. However, despite the serious implications of weak alignment research and practice both tend to focus on one or the other of RE or VV rather than on the alignment of the two. We have performed a multi-unit case study to gain insight into issues around aligning RE and VV by interviewing 30 practitioners from 6 software developing companies, involving 10 researchers in a flexible research process for case studies. The results describe current industry challenges and practices in aligning RE with VV, ranging from quality of the individual RE and VV activities, through tracing and tools, to change control and sharing a common understanding at strategy, goal and design level. The study identified that human aspects are central, i.e. cooperation and communication, and that requirements engineering practices are a critical basis for alignment. Further, the size of an organisation and its motivation for applying alignment practices, e.g. external enforcement of traceability, are variation factors that play a key role in achieving alignment. Our results provide a strategic roadmap for practitioners improvement work to address alignment challenges. Furthermore, the study provides a foundation for continued research to improve the alignment of RE with VV.

description: We present a detailed study of the internal kinematics of the Galactic Globular Cluster M 4 (NGC 6121), by deriving the radial velocities from 7250 spectra for 2771 stars distributed from the upper part of the Red Giant Branch down to the Main Sequence. We describe new approaches to determine the wavelength solution from day-time calibrations and to determine the radial velocity drifts that can occur between calibration and science observations when observing with the GIRAFFE spectrograph at VLT. Two techniques to determine the radial velocity are compared, after a qualitative description of their advantages with respect to other commonly used algorithm, and a new approach to remove the sky contribution from the spectra obtained with fibre-fed spectrograph and further improve the radial velocity precision is presented. The average radial velocity of the cluster is $\langle v \rangle = 71.08 \pm 0.08$ km s$^{-1}$ with an average dispersion of $μ_{v_c} = 3.97$ km s$^{-1}$. Using the same dataset and the same statistical approach of previous analyses, 20 additional binary candidates are found, for a total of 87 candidates. A new determination of the internal radial velocity dispersion as a function of cluster distance is presented, resulting in a dispersion of $4.5$ km s$^{-1}$ within 2$^{\prime}$ from the center of cluster and steadily decreasing outward. We statistically confirm the small amplitude of the cluster rotation, as suggested in the past by several authors. This new analysis represents a significant improvement with respect to previous results in literature and provides a fundamental observational input for the modeling of the cluster dynamics.

description: High-Q silicon nitride (SiN) microresonators enable optical Kerr frequency comb generation on a photonic chip and have recently been shown to support fully coherent combs based on temporal dissipative Kerr soliton formation. For bright soliton formation it is necessary to operate SiN waveguides in the multimode regime so as to produce anomalous group velocity dispersion. This can lead to local disturbances of the dispersion due to avoided crossings caused by coupling between different mode families, and therefore prevent the soliton formation. Here we demonstrate that a single mode "filtering" section inside high-Q resonators enables to efficiently suppress avoided crossings, while preserving high quality factors (Q~10^6). We demonstrate the approach by single soliton formation in SiN resonators with filtering section.
Approaches to Learning in Kindergarten: Associations with Child and Family Background Variables
Creators: name: Bundy, Maria Pelzer
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: The study analyzed a nationally representative sample of first-time kindergarteners from the Early Childhood Longitudinal Study - Kindergarten cohort of 1998-1999. Associations between sociodemographic risk factors, including race/ethnicity, poverty status, maternal education, child care participation, and residential location, and the dimension of approaches to learning for young children were analyzed at kindergarten entry. Race/ethnicity and maternal education predicted unique proportions of variance in children's approaches to learning (AL) at kindergarten entry. Race/ethnicity was associated with AL such that African American, Native American, and Hispanic children had the lowest scores on AL, while White and Asian children had the highest scores on AL. Maternal education was associated with AL such that children whose mothers had a four-year college degree or graduate/professional degree had higher AL scores than those whose mothers had any education less than a college degree. Implications of these findings for practice and policy are discussed.

description: We investigate the decays of the excited $(b\bar q)$ mesons as probes of the short-distance structure of the weak $ΔB=1$ transitions. These states are unstable under the electromagnetic or strong interactions although their widths are typically suppressed by phase space. As compared to the pseudoscalar $B$ meson, the purely leptonic decays of the vector $B^*$ are not chirally suppressed and are sensitive to different combinations of the underlying weak effective operators. An interesting example is $B^*_s\to \ell^+\ell^-$, which has a rate that can be accurately predicted in the standard model. The branching fraction is $\mathcal{B}\sim10^{-11}$, irrespective of the lepton flavor and where the main uncertainty stems from the unmeasured and theoretically not-well known $B_s^*$ width. We discuss the prospects for producing this decay mode at the LHC and explore the possibility of measuring the $B_s^*\to\ell\ell$ amplitude, instead, through scattering experiments at the $B_s^*$ resonance peak. Finally we also discuss the charged-current $B_{u,c}^*\to\ellν$ decay which can provide complementary information on the $b\to u\ellν$ and $b\to c\ellν$ transitions.
