The poison frogs (family Dendrobatidae) are terrestrial anuran amphibians displaying a wide range of coloration and toxicity. These frogs generally have been considered to be aposematic, but relatively little research has been carried out to test the predictions of this hypothesis. Here we use a comparative approach to test one prediction of the hypothesis of aposematism: that coloration will e...

Previously encountered stimuli can bring to mind a vivid memory of the episodic context in which the stimulus was first experienced ("remembered" stimuli), or can simply seem familiar ("known" stimuli). Past studies suggest that more attentional resources are required to encode stimuli that are subsequently remembered than known. However, it is unclear if the attentional resources are distribut...

The traditional mapping on digital aerial photos and elevation models has its limits at steep slopes where the surface is only very sparsely sampled even in high resolution data sets. As a consequence, there is too few information available to perform a detailed mapping. In this paper we present a framework for augmenting terrain data with additional photos and show how to utilize this addition...

The modern literature explaining the under-representation of women in science often relate to the shortage of women ‘in the pipeline’. The pipeline flows from one stage to another, and the flow of women diminishes over the stages. Speaking of the stages of career during which women scientists ‘leak’ the most, the commercialisation of science as one of the ultimate stages should be taken into co...

In this work, we analyze more than two million news photos published in January 2016. To our best knowledge, this is the first large-scale study of news photos by the GDELT project and deep learning-based vision APIs.
