208276.pdf (Publisher’s version ) (Open Access)When asking 'What makes us humans unique?' people often think of qualities like the ability to reason and to make well considered choices. Yet, in reality we do not compute all our choices like computers. That would not work! Therefore we often rely on simple heuristics that are not completely rational. New research from Jennifer Swart shows that even learning from experience can be susceptible to such heuristics. Some actions are easier learned that others, because they are more in line with your view of how the world works. It is easier to learn to take action for example than to learn to hold back when you know your behaviour leads to pleasant outcomes. These irrational learning processes appear to rely on the same primitive brain regions as the simple heuristics. More developed brain regions can help to deviate from the irrational behaviour when necessary.Radboud University, 29 maart 2019Promotores : Cools, R., Frank, M.J. Co-promotor : Ouden, H.E.M. den190 p
Data for "Wildfire smoke cools summer river and stream water temperatures"
No full textThese data were used in an analysis of the effects of wildfire smoke on river and stream water temperatures, air temperatures, and solar radiation in the lower Klamath River Basin, California, USA. These data were assembled and analyzed by Aaron T. David, J. Eli Asarian, and Frank K. Lake. The publication describing these data and the results and interpretation of our analysis is titled: "Wildfire smoke cools summer river and stream water temperatures."

Large Time Step and DC Stable TD-EFIE Discretized with Implicit Runge-Kutta Methods
No full textThe time domain-electric field integral equation (TD-EFIE) and its differentiated version are widely used to simulate the transient scattering of a time dependent electromagnetic field by a perfect electric conductor (PEC). The time discretization of the TD-EFIE can be achieved by a space-time Galerkin approach or, as it is considered in this contribution, by a convolution quadrature using implicit Runge-Kutta methods. The solution is then computed using the marching-on-in-time (MOT) algorithm. The differentiated TD-EFIE has two problems: 1) the system matrix suffers from ill-conditioning when the time step increases (low frequency breakdown) and 2) it suffers from the DC instability, i.e., the formulation allows for the existence of spurious solenoidal currents that grow slowly in the solution. In this article, we show that 1) and 2) can be alleviated by leveraging quasi-Helmholtz projectors to separate the Helmholtz components of the induced current and rescale them independently. The efficacy of the approach is demonstrated by numerical examples including benchmarks and real-life applications.Numerical Analysi

No full textLiterature and the nugget of knowledge : an interview with Derek Attridge and Peter Lamarque
No full textAbstract: The idea of an interview with Peter Lamarque and Derek Attridge on the cognitive value of literary fiction arose in the wake of an aesthetics course on the relation between literature and truth at the University of Antwerp. In Spring 2015 Peter Lamarque contributed to this course with the lecture \u201cThe Opacity of Narrative and Fine-grained Reading\u201d. In Spring 2017 Derek Attridge elaborated his view on the relation between literature and truth in his lecture \u201cThe Event of Truth : Literature\u2019s Singular Relation to Knowledge\u201d. After each lecture, we had the occasion to discuss with the author the stakes of the debate and we were rapidly convinced by the many points of convergences between their views. We intended to explore these similarities and differences through a face to face interaction and were happy that both philosophers accepted our invitation for an interview. This interview was conducted by Arthur Cools and Leen Verheyen in York on 9 July 2018
