Novel Age-Dependent Cortico-Subcortical Morphologic Interactions Predict Fluid Intelligence: A Multi-Cohort Geometric Deep Learning Study

The relationship of human brain structure to cognitive function is complex, and how this relationship differs between childhood and adulthood is poorly understood. One strong hypothesis suggests the cognitive function of Fluid Intelligence (Gf) is dependent on prefrontal cortex and parietal cortex. In this work, we developed a novel graph convolutional neural networks (gCNNs) for the analysis of localized anatomic shape and prediction of Gf. Morphologic information of the cortical ribbons and subcortical structures was extracted from T1-weighted MRIs within two independent cohorts, the Adolescent Brain Cognitive Development Study (ABCD; age: 9.93 ± 0.62 years) of children and the Human Connectome Project (HCP; age: 28.81 ± 3.70 years). Prediction combining cortical and subcortical surfaces together yielded the highest accuracy of Gf for both ABCD (R = 0.314) and HCP datasets (R = 0.454), outperforming the state-of-the-art prediction of Gf from any other brain measures in the literature. Across both datasets, the morphology of the amygdala, hippocampus, and nucleus accumbens, along with temporal, parietal and cingulate cortex consistently drove the prediction of Gf, suggesting a significant reframing of the relationship between brain morphology and Gf to include systems involved with reward/aversion processing, judgment and decision-making, motivation, and emotion.

3. The —omics revolution

In the past, experiments were time consuming and expensive, and data were therefore often scarce. The so-called —omics revolution has changed this situation to a point where we often have so many data that we cannot make sense of them and need to resort to sophisticated computing methods. ‘The —omics revolution’ explains how this shift has changed how we perform experiments and think about science. The —omics revolution—with fields of study such as genomics and proteomics—has not only generated huge datasets, it has turned the tried-and-true scientific method on its head. The central position of a strong hypothesis has all but vanished, and the new mindset is exploratory data analysis.

Visual SLAM Based on Dynamic Object Removal

Visual simultaneous localization and mapping (SLAM) is the core of intelligent robot navigation system. Many traditional SLAM algorithms assume that the scene is static. When a dynamic object appears in the environment, the accuracy of visual SLAM can degrade due to the interference of dynamic features of moving objects. This strong hypothesis limits the SLAM applications for service robot or driverless car intherealdynamicenvironment.Inthispaper,adynamicobject removal algorithm that combines object recognition and optical flow techniques is proposed in the visual SLAM framework for dynamic scenes. The experimental results show that our new method can detect moving object effectively and improve the SLAM performance compared to the state of the art methods.<br>

Income Redistribution Predicts Greater Life Satisfaction Across Individual, National, and Cultural Characteristics.

The widening income gap between the rich and the poor has important social implications. Governmental-level income redistribution through tax and welfare policies presents an opportunity to reduce income inequality and its negative consequences. The current longitudinal studies examined whether within-region changes in income redistribution over time relate to life satisfaction. Moreover, I examined potential moderators of this relationship to test the strong versus weak hypotheses of income redistribution. The strong hypothesis posits that income redistribution is beneficial to most. The weak hypothesis posits that income redistribution is beneficial to some and damaging to others. Using a nationally representative sample of 57,932 German respondents from 16 German states across 30 years (Study 1) and a sample of 112,876 respondents from 33 countries across 24 years (Study 2), I found that within-state and within-nation changes in income redistribution over time were associated with life satisfaction. The models predicted that a 10% reduction in Gini through income redistribution in Germany increased life satisfaction to the same extent as an 37% increase in annual income (Study 1), and a 5% reduction in Gini through income redistribution increased life satisfaction to the same extent as a 11% increase in GDP (Study 2). These associations were positive across individual, national, and cultural characteristics. Increases in income redistribution predicted greater satisfaction for tax-payers and welfare-receivers, for liberals and conservatives, and for the poor and the rich. These findings support the strong hypothesis of income redistribution and suggest that redistribution policies may play an important role in societal well-being.

HUBUNGAN KESELAMATAN DAN KESEHATAN KERJA (K3) DENGAN KINERJA KARYAWAN PADA PT. UOB INDONESIA CABANG BENGKULU

Ida Ayu Er. Meytha Gayatri; The purpose of this study was to determine the relationship of Occupational Health and Safety (K3) place. the performance of employees in the branch of PT. UOB Indonesia Bengkulu Branch. From the calculation of the Spearman rank correlation coefficient analysis of the amount of 0.89 or 0.80 to 1.000 rho in a very strong, which means that the relationship between the variables of Occupational Health and Safety (K3) with the performance of employees of PT. UOB Indonesia Bengkulu Branch relate very strong. Hypothesis testing results, from 14.863 t and t table is 2.0003 or (14.863> 2.0003), then Ho is rejected and Ha accepted means there is a significant relationship between occupational safety and health (K3) with the performance of employees at PT.

Kelvin wake pattern at large Froude numbers

Gravity waves generated by an object moving at constant speed at the water surface form a specific pattern commonly known as the Kelvin wake. It was proved by Lord Kelvin that such a wake is delimited by a constant angle ${\simeq }19. 4{7}^{\circ } $. However a recent study by Rabaud and Moisy based on the observation of airborne images showed that the wake angle seems to decrease as the Froude number $Fr$ increases, scaling as $F{r}^{- 1} $ for large Froude numbers. To explain such observations they make the strong hypothesis that an object of size $b$ cannot generate wavelengths larger than $b$. Without the need of such an assumption and modelling the moving object by an axisymmetric pressure field, we analytically show that the angle corresponding to the maximum amplitude of the waves scales as $F{r}^{- 1} $ for large Froude numbers, whereas the angle delimiting the wake region outside which the surface is essentially flat remains constant and equal to the Kelvin angle for all $Fr$.

Introduction: Interface Asymmetries

The articles assembled in this issue of the Canadian Journal of Linguistics/Revue canadienne de linguistique contribute to our understanding of the role of asymmetric relations at the interfaces. Asymmetric relations have privileged status in the syntactic, phonological, and morphological derivation of linguistic expressions (see for example the articles in Di Sciullo 2003).Interfaces are representations that must meet legibility conditions imposed by external systems. According to the Strong Minimalist Thesis (Chomsky 2001), language is an optimal solution to interface conditions, in that language is an optimal way to link sound and meaning. Questions arise regarding the properties of the interface representations that make them optimally legible by external systems. These properties could very well be abstract, and remote from the perceptual systems, and could bear on the form of interface representations, rather than on the interpretation of their parts. A strong hypothesis in this regard is that asymmetric relations are core properties of the relations derived by the grammar (Chomsky 1981, 1995, 2001; Kayne 1994; Moro 2000; Di Sciullo 2005; Zwart 2006). From this perspective, asymmetry is a pervasive property of derivations and interface representations; it is thus expected to be a property of different structural relations, such as the relation between a displaced constituent and its copy, the relation between an anaphor and its antecedent, the relation between a head and its dependent, and more generally, the relation between the constituents of a configuration.
