Perhaps because of its prominence in midline sections of the human brain, the corpus callosum, one of the few brain structures identifiable by even the slowest student, has attracted wide interest throughout history. Cajal described how the visual field representation was first inverted by the lens of the eye and split into two halves, represented in the two hemispheres, and then knit together ...

Educational games link the motivational nature of games with learning of knowledge and skills. Here, we go beyond effects on these learning outcomes. We review two lines of evidence which indicate the currently unexplored potential of educational games to promote brain health: First, gaming with specific neurocognitive demands (e.g., executive control), and second, educational learning experien...

This paper presents an improved adaptive-neighborhoodcontrast-enhancement (ANCE) method for improvement of medical image quality. The ANCE method consists of computing a local contrast around each pixel using a variable neighborhood whose size depends on the statistical properties around the given pixel. The obtained contrast image is then transformed into a new contrast image using a contrast ...

The Differentiated Services (DS) architecture has been defined for implementing scalable service differentiation in the Internet. DS edge routers employ traffic conditioners that contain meter, marker and shaper functionalities. The way of traffic shaping in traffic conditioners is an open issue and we believe, using intelligent shaping algorithms instead of leaky bucket algorithms (LBAs) could...

LDPC lattices were the first family of lattices that equipped with iterative decoding algorithms under which they perform very well in high dimensions. In this paper, we introduce quasi cyclic low density parity check (QC-LDPC) lattices as a special case of LDPC lattices with one binary QC-LDPC code as their underlying code. These lattices are obtained from Construction A of lattices providing ...

We aim to disentangle the relative impact of (i) cognitive ability and (ii) education on health and mortality using a structural equation model suggested by Conti et al. (2010). We extend their model by allowing for a duration dependent variable (mortality), and an ordinal educational variable. Data come from a Dutch cohort born between 1937 and 1941, including detailed measures of cognitive ab...
