TL;DR: In this article, the critical couplings for the deconfinement phase transition in SU(2) gauge theory on Nτ × Nσ3 lattices with Nτ = 8 and 16 and Nσ varying between 16 and 48 were determined.

TL;DR: An extended approach to understand migrant health comprising a life course epidemiology perspective is discussed, which enables the consideration of risk factors and disease outcomes over the different life phases of migrants, which is necessary to understand the health situation of migrants and their offspring.
Abstract: Empirical findings show that morbidity and mortality risks of migrants can differ considerably from those of populations in the host countries However, while several explanatory models have been developed, most migrant studies still do not consider explicitly the situation of migrants before migration Here, we discuss an extended approach to understand migrant health comprising a life course epidemiology perspective The incorporation of a life course perspective into a conceptual framework of migrant health enables the consideration of risk factors and disease outcomes over the different life phases of migrants, which is necessary to understand the health situation of migrants and their offspring Comparison populations need to be carefully selected depending on the study questions under consideration within the life course framework Migrant health research will benefit from an approach using a life course perspective A critique of the theoretical foundations of migrant health research is essential for further developing both the theoretical framework of migrant health and related empirical studies

TL;DR: In this article, the second and fourth-order cumulants of these fluctuations were analyzed and it was shown that the ratio of quartic and quadratic cumulant reflects the degrees of freedom that carry the quark number, isospin or charge, respectively.

TL;DR: The authors found that the effects of n Ach and san Ach on students' performance were mediated by the anticipated affective value of achievement outcomes, which is discussed in relation to a 2-system approach to achievement motivation.
Abstract: This research examined how implicit and self-attributed needs to achieve (labeled as n Ach and san Ach, respectively) combine with self-referenced and norm-referenced feedback to predict effort-related (task performance) and choice-related (task continuation) indexes of students' engagement in a mental concentration task. In Experiment 1 the authors found that in a task-focused setting, task performance was predicted by the joint effect of self-referenced feedback and n Ach, whereas task continuation was predicted by the joint effect of norm-referenced feedback and san Ach. In Experiment 2 the authors found that in an ego-focused setting, n Ach and san Ach interacted in the prediction of task performance but not of task continuation. In Experiment 3 the authors found that the effects of n Ach and san Ach on students' performance were mediated by the anticipated affective value of achievement outcomes. These findings are discussed in relation to a 2-system approach to achievement motivation.

TL;DR: A detailed overview of the cosmological surveys that we aim to carry out with Phase 1 of the Square Kilometre Array (SKA1) and the science that they will enable can be found in this paper.
Abstract: We present a detailed overview of the cosmological surveys that we aim to carry out with Phase 1 of the Square Kilometre Array (SKA1) and the science that they will enable. We highlight three main surveys: a medium-deep continuum weak lensing and low-redshift spectroscopic HI galaxy survey over 5 000 deg2; a wide and deep continuum galaxy and HI intensity mapping (IM) survey over 20 000 deg2 from $z = 0.35$ to 3; and a deep, high-redshift HI IM survey over 100 deg2 from $z = 3$ to 6. Taken together, these surveys will achieve an array of important scientific goals: measuring the equation of state of dark energy out to $z \sim 3$ with percent-level precision measurements of the cosmic expansion rate; constraining possible deviations from General Relativity on cosmological scales by measuring the growth rate of structure through multiple independent methods; mapping the structure of the Universe on the largest accessible scales, thus constraining fundamental properties such as isotropy, homogeneity, and non-Gaussianity; and measuring the HI density and bias out to $z = 6$ . These surveys will also provide highly complementary clustering and weak lensing measurements that have independent systematic uncertainties to those of optical and near-infrared (NIR) surveys like Euclid, LSST, and WFIRST leading to a multitude of synergies that can improve constraints significantly beyond what optical or radio surveys can achieve on their own. This document, the 2018 Red Book, provides reference technical specifications, cosmological parameter forecasts, and an overview of relevant systematic effects for the three key surveys and will be regularly updated by the Cosmology Science Working Group in the run up to start of operations and the Key Science Programme of SKA1.
