description: These lecture notes address a central problem of theoretical nuclear physics: how to establish a relationship between low-energy, non-perturbative QCD and nuclear phenomenology which includes both nuclear matter and finite nuclei. We develop a microscopic covariant description of nuclear many-body dynamics constrained by chiral symmetry and in-medium QCD sum rules. A relativistic point-coupling model is derived, based on an effective Lagrangian with density-dependent contact interactions between nucleons. These interactions are constructed from chiral one- and two-pion exchange, combined with the large isoscalar nucleon self-energies that arise through changes in the quark condensate and the quark density at finite baryon density. Nuclear binding and saturation are almost completely generated by chiral (two-pion exchange) fluctuations in combination with Pauli effects, whereas strong scalar and vector fields of about equal magnitude and opposite sign, induced by changes of the QCD vacuum in the presence of baryonic matter, generate the large effective spin-orbit potential in finite nuclei. Promising results are found for the nuclear matter equation of state and for the bulk and single-nucleon properties of finite nuclei.

description: The gate-voltage-induced suppression of critical currents in metallic superconductors observed recently [De Simoni et al., Nat. Nanotechnol. 13, 802 (2018)] has raised crucial questions regarding the nature and mechanism of the electric field effect in these systems. Here, we demonstrate an enhancement of up to 30 % in critical current in the type II superconductor NbN, micro- and nano superconducting bridges, tunable via a back-gate voltage. Our suggested plausible mechanism of this enhancement in critical current based on surface nucleation and pinning of Abrikosov vortices is consistent with expectations and observations for type-II superconductor films with thicknesses comparable to their coherence length. Furthermore we demonstrate infinite electroresistance and a hysteretic resistance dependence on the applied electric field which could lead to logic and memory applications in a superconductors-based low-dissipation digital computing paradigm. Our work thus provides the first demonstration of an electric field enhancement in the superconducting property in metallic superconductors, constituting a crucial step towards understanding of electric field-effects on the fundamental properties of a superconductor and its exploitation for future technologies.

description: The concept of the Wigner function is used to construct a semi-classical kinetic theory describing the evolution of the axial-current phase-space density of spin-1/2 particles in the relaxation time approximation. The resulting approach can be used to study spin-polarization effects in relativistic matter, in particular, in heavy-ion collisions. An expression for the axial current based on the classical treatment of spin is also introduced and we show that it is consistent with earlier calculations using Wigner functions. Finally, we derive non-equilibrium corrections to the spin tensor, which are used to define, for the first time, the structure of spin transport coefficients in relativistic matter.

description: Based on data from the Bureau of the Census' 1982 Survey of Real Property Transfer Records, there were an estimated 10.6 million deeds recorded in 1979. Real property transfer records are a potential source of data on land ownership, value, and size. These data are important to professionalgtoups concerned with the development, distribution, and use of land resources. The present limitations of transfer data for studies of land values and ownership could be reduced by standardizing forms and improving coordination among data users.

description: We present a numerical study of an idealized magnetohydrodynamic (MHD) configuration consisting of a planar wake flow embedded into a three-dimensional (3D) sheared magnetic field. Our simulations investigate the possibility for in-situ development of large-scale compressive disturbances at cospatial current sheet -- velocity shear regions in the heliosphere. Using a linear MHD solver, we first systematically chart the destabilized wavenumbers, corresponding growth rates, and physical parameter ranges for dominant 3D sinuous-type instabilities in an equilibrium wake--current sheet system. Wakes bounded by sufficiently supersonic (Mach number $M_s > 2.6$) flow streams are found to support dominant fully 3D sinuous instabilities when the plasma beta is of order unity. Fully nonlinear, compressible 2.5D and 3D MHD simulations show the self-consistent formation of shock fronts of fast magnetosonic type. They carry density perturbations far away from the wake's center. Shock formation conditions are identified in sonic and Alfvénic Mach number parameter space. Depending on the wake velocity contrast and magnetic field magnitude, as well as on the initial perturbation, the emerging shock patterns can be plane-parallel as well as fully three-dimensionally structured. Similar large-scale transients could therefore originate at distances far above coronal helmet streamers or at the location of the ecliptic current sheet.

description: In the 1980s, economic difficulties caused some rural localities to rely on their own financial and organizational resources to initiate projects generating local jobs or income. The authors set out to systematically study this phenomenon, which was designated "self-development." Through a survey, information was obtained on 103 self-development projects. This publication of profiles of each of these cases is aimed at providing useful information to community leaders and development professionals about those projects: name and location, a brief project description, involvement of local organizations, an estimate of income and/or number of jobs generated, and the means by which the project was financed. Types of projects include (1) community-based development (community-owned and worker-owned firms, agricultural marketing organizations, community finance institutions, community-based service firms, etc.), (2) local business and industrial development (locally owned industrial and value-added firms, business incubators, retention and expansion programs), and (3) tourism and historical development (recreational development, festivals, crafts fairs, downtown revitalization). Local contact persons are listed. A comprehensive index is included.

description: We have searched for OH absorption against seven pulsars using the Arecibo telescope. In both OH mainlines (at 1665 and 1667 MHz), deep and narrow absorption features were detected toward PSR B1849+00. In addition, we have detected several absorption and emission features against B33.6+0.1, a nearby supernova remnant (SNR). The most interesting result of this study is that a pencil-sharp absorption sample against the PSR differs greatly from the large-angle absorption sample observed against the SNR. If both the PSR and the SNR probe the same molecular cloud then this finding has important implications for absorption studies of the molecular medium, as it shows that the statistics of absorbing OH depends on the size of the background source. We also show that the OH absorption against the PSR most likely originates from a small (<30 arcsec) and dense (>10^5 cm^-3) molecular clump.

description: The relationship between food and the environment has been steadily and increasingly endorsed in recent years, and it is at this junction where the potential for human intervention is substantial (Willett et al., 2019). The statement “feeding nine billion” is frequently included in discourse concerning future physical, environmental and social health, this statement aptly encompasses the importance of food in terms of sufficient nutrition, but also the immense demand for resources required to achieve this goal. There is already disparity in the health of the global population, with millions individuals lacking sufficient nutrition, and millions more affected by chronic diseases associated with overnutrition and poor diet, and it is likely that the current patterns of food consumption and production will not amend these obstacles, if left unchanged (Lindgren et al., 2018). Furthermore, the EAT Lancet Commission (2019) encompasses the importance of food within the context of climate change, stating, “Food is the single strongest lever to optimize human health and environmental sustainability of Earth”. Despite a somewhat dismal outlook at the fate of the planet, this statement can inspire and encourage individuals to make changes, no matter how small, in efforts to live sustainably for environmental and health benefits. The overarching recommendation in order to positively modify the environmental impacts of food consumption and production require switching to primarily plant-based diets (Mertens et al, 2017; Shepon et al., 2018; Tilman & Clark, 2014). These dietary changes are said to promote the greatest improvement in population health but also the greatest reduction in the impact of diet upon resources. It is through these recommendations that food can be seen as a vehicle for change, thus supporting integration of more plant-based options into the Nest Catering menu. This partnership with Nest Catering will increase the prevalence and marketing of plant-based meal options, through which perceptions of those who use AMS catering services, can shift toward sustainable food options.

description: This paper explains how U.S. agricultural policies are modeled in the 30-sector computable general equilibrium (CGE) model of the United States called the FPGE GAMS model (Earm Policy in General Equilibrium, General Algebraic Modeling System). The main features of the FPGE GAMS model are (1) farm programs are modeled explicitly rather than by using ad valorem equivalents; (2) every dollar spent and received under farm programs is accounted for; and (3) the facts that farm households earn nonfarm income and nonfarm households own farmland is made explicit. Policy modeling issues are discussed. There is a detailed explanation of the equations representing farm programs, spending, and program effects. Data sources and methods of calibration and parameterization are explained. A social accounting matrix (SAM) of the United States highlighting farm program expenditures and receipts is included.

description: Demand for grain in the Soviet Union has increased, but supply has only partially met the need. While average grain yields have increased on unchanged area, they have become increasingly unstable. The result is that the Soviet Union has shifted some of its domestic production instability to international grain markets. This study examines Soviet grain production stability with time series analysis and finds it related to Soviet net grain imports and imports from the United States. It also examines some recent Soviet efforts to reduce grain yield instability.

description: Separating high-dimensional data like images into independent latent factors, i.e independent component analysis (ICA), remains an open research problem. As we show, existing probabilistic deep generative models (DGMs), which are tailor-made for image data, underperform on non-linear ICA tasks. To address this, we propose a DGM which combines bijective feature maps with a linear ICA model to learn interpretable latent structures for high-dimensional data. Given the complexities of jointly training such a hybrid model, we introduce novel theory that constrains linear ICA to lie close to the manifold of orthogonal rectangular matrices, the Stiefel manifold. By doing so we create models that converge quickly, are easy to train, and achieve better unsupervised latent factor discovery than flow-based models, linear ICA, and Variational Autoencoders on images.

Powder X-ray diffraction revealed a change of the crystal structure from tetragonally compressed to tetragonally elongated orthorhombic between x=0.75 and x=0.8 in the CO state, resulting from the crossover of the cooperative Jahn-Teller vibration mode from Q2 to Q3. The relative stiffening of the ultrasound (DeltaV/V) reflecting the magnitude of the cooperative Jahn-Teller lattice distortion in the CO state increases with increasing x from 0.5 to 0.625, reaching the largest and being almost x-independence for 0.625

description: VLBA and EVN radio observations of H2O masers at 22 GHz and methanol masers at 6.7 GHz have been used to obtain images of the maser spots in the infrared object GL2789, which is associated with the young stellar object V645Cyg. The position of these masers coincides with that of the optical object to within 0.2 arcsec. The maser spots are located in a line oriented north--south, and their positions and radial velocities can be described by a model with a Keplerian disk with maximum radius 40 AU for the H2O masers and 800 AU for the methanol masers. The H2O and methanol masers spots are unresolved, and the lower limits for their brightness temperatures are 2x10^{13} K and 1.4x10^9 K, respectively. A model in which the maser radiation is formed in extended water-methanol clouds associated with ice planets forming around the young star is proposed.

title: Protective Effects of Social Support and Self-Esteem on Sexual Minority Young Adults' Mental Health
Creators: name: Bock, Sara
Publisher: name: Old Dominion University
Year: 2014

description: Existing research has established that lesbian, gay and bisexual (LGB) youths experience higher rates of mental illness. However, fewer studies have examined what influences these disparate outcomes. Meyer's (2003) minority stress theory suggests that social factors, such as social support, and internal resources, such as self-esteem, are important potential moderators that may buffer the detrimental effects of stigma-related stress for sexual minority individuals. This study examined the potential protective effects peer support, parent support, school support, and self-esteem in adolescence in explaining mental health disparities between sexual minority and heterosexual young adults. Mental health outcomes included alcohol consumption, depressive symptoms, delinquency, and suicidal ideation (SI). Data were from waves I (1994-1995) and III (2001-2002) of the Add Health restricted-use dataset, a longitudinal, nationally representative survey of American adolescents. A series of multiple and logistic regressions was conducted to examine whether peer, parent, and school support or self­ esteem in adolescence moderated the relationship between sexual identity and each of the four mental health outcomes at young adulthood, controlling for mental health symptom levels at adolescence. Overall, findings revealed that received peer support in adolescence is a protective factor for 100% homosexual young adults at risk for higher alcohol consumption, and for bisexual young adults at risk for depressive symptoms. Neither of the perceived support variables (i.e., peer and parent) acted as protective factors for increased mental health symptoms among sexual minority individuals in young adulthood after accounting for mental health symptom levels in adolescence. Results suggest the importance of peer support and self-esteem in adolescence in predicting future depressive symptoms and alcohol consumption among sexual minority individuals. Results also indicate that trajectories of alcohol consumption, depressive symptoms, delinquency and SI may differ by sexual identity, suggesting the need for future studies to include multiple sexual identities (e.g., mostly heterosexual).

description: Adhesive interactions between elastic structures such as graphene sheets, carbon nanotubes, and microtubules have been shown to exhibit hysteresis due to irrecoverable energy loss associated with bond breakage, even in static (rate-independent) experiments. To understand this phenomenon, we start with a minimal theory for the peeling of a thin sheet from a substrate, coupling the local event of bond breaking to the nonlocal elastic relaxation of the sheet and show that this can drive static adhesion hysteresis over a bonding/debonding cycle. Using this model we quantify hysteresis in terms of the adhesion and elasticity parameters of the system. This allows us to derive a scaling relation that preserves hysteresis at different levels of granularity while resolving a seeming paradox of lattice trapping in the continuum limit of a discrete fracture process. Finally, to verify our theory, we use new experiments to demonstrate and measure adhesion hysteresis in bundled microtubules.

description: We explore the possibility for the reconstruction of the generative physical models describing interactions between atomic units in solids from observational electron microscopy data. Here, scanning transmission electron microscopy (STEM) is used to observe the dynamic motion of Si atoms at the edge of monolayer graphene under continuous electron beam illumination. The resulting time-lapsed STEM images represent the snapshots of observed chemical states of the system. We use two approaches: potential of mean force (PMF) calculation using a radial distribution function (RDF) and a direct fitting of the graphene-Si interatomic pair-wise potentials with force matching, to reconstruct the force fields in the materials. These studies lay the foundation for quantitative analysis of materials energetics from STEM data through the sampling of the metastable states in the chemical space of the system.

description: Most the literature on urban sprawl and the urban conversion of farmland hypothesizes that direct and indirect government policies inadvertently provide incentives that foster discontiguous urban development [see Boling, Dunford, Clawson]. Although merely responding to these incentives and constraints, developers make key locational decisions that are responsible for discontiguous urban growth [see Kaiser and Weiss; Clawson]. It is often hypothesized that in an effort to maximize profit, developers select first those parcels that have the site and accessibility characteristics most desired by consumers. This argument suggests that discontiguous urban growth occurs because the parcel characteristics desired by housing consumers and sought by developers are widely and randomly scattered throughout the urbanizing area. For instance, Kaiser [pp. 351-352] "attempts to illustrate conceptually and verify empirically that the factors in— fluencing the developer's profit motivated locational decisions include, but are by no means limited to, characteristics of consumer demand." He goes on to conclude that [p. 361], "on a fairly general level, the empirical analysis supports the hypothesis that the locational decision should be substantially explainable by the list of site charactertistics involved in every such decision."

New views of the solar wind with the Lambert W function

description: This paper presents closed-form analytic solutions to two illustrative problems in solar physics that have been considered not solvable in this way previously. Both the outflow speed and the mass loss rate of the solar wind of plasma particles ejected by the Sun are derived analytically for certain illustrative approximations. The calculated radial dependence of the flow speed applies to both Parker's isothermal solar wind equation and Bondi's equation of spherical accretion. These problems involve the solution of transcendental equations containing products of variables and their logarithms. Such equations appear in many fields of physics and are solvable by use of the Lambert W function, which is briefly described. This paper is an example of how new functions can be applied to existing problems.

description: The Undergraduate Experience Survey (UES) currently asks students about their satisfaction with the quality, costs, and availability of healthy and nutritious foods on campus. However, the data collected does not provide insight to students’ understanding of the concepts nor their reasons for the satisfaction rating given. Through this project, we aim to gather information on how students interpret “cost”, “availability” and “quality” of healthy food on campus, along with their overall food experience on campus, with a focus on the latter. The results of this project will lead to future actions that will help achieve the UBC Wellbeing Strategy for a “nutritionally sound campus (UBC Wellbeing, 2017).” Our situational assessment included communications with community partner Natasha Moore, Melissa Baker, the former Manager of Nutrition & Wellbeing at Student Housing and Hospitality Services (SHHS), and literature review to determine steps taken when assessing students’ perceptions of campus foods. We determined using a survey and focus groups were ideal in collecting data, along with use of the Social Ecological Model (SEM) to assess students’ responses. As described in the report, the project outputs include an initial survey that provides insight on the clarity of questions to be used in the focus group surveys, and to provide an initial outlook on students’ understanding of the terms in question. Two, one-hour focus groups were conducted to further assess students’ experiences with the food environment at UBC as it relates to cost, availability and quality of healthy foods. Themes that are discussed hereon in relation to the Social Ecological Model.

description: Knowledge tracing, the act of modeling a student's knowledge through learning activities, is an extensively studied problem in the field of computer-aided education. Although models with attention mechanism have outperformed traditional approaches such as Bayesian knowledge tracing and collaborative filtering, they share two limitations. Firstly, the models rely on shallow attention layers and fail to capture complex relations among exercises and responses over time. Secondly, different combinations of queries, keys and values for the self-attention layer for knowledge tracing were not extensively explored. Usual practice of using exercises and interactions (exercise-response pairs) as queries and keys/values respectively lacks empirical support. In this paper, we propose a novel Transformer based model for knowledge tracing, SAINT: Separated Self-AttentIve Neural Knowledge Tracing. SAINT has an encoder-decoder structure where exercise and response embedding sequence separately enter the encoder and the decoder respectively, which allows to stack attention layers multiple times. To the best of our knowledge, this is the first work to suggest an encoder-decoder model for knowledge tracing that applies deep self-attentive layers to exercises and responses separately. The empirical evaluations on a large-scale knowledge tracing dataset show that SAINT achieves the state-of-the-art performance in knowledge tracing with the improvement of AUC by 1.8% compared to the current state-of-the-art models.
