Pitch size varies in official soccer matches and differently sized pitches are adopted for tactical purposes in small-sided training games. Since interactive team behaviour emerges under constraints, the authors evaluate the effect of pitch size (task) manipulations on interactive team behaviour in small-sided …

In January 2008 the online photo-hosting site Flickr introduced a new section entitled The Commons. Its two key goals were to show the hidden treasures in the world’s public photography archives to the general public and to give Flickr community members the opportunity to contribute and describe these …

Background: G-protein coupled receptors (GPCRs) are involved in many different physiological processes and their function can be modulated by small molecules which bind in the transmembrane (TM) domain. Because of their structural and sequence conservation, the TM domains are often used in bioinformatics …

In this article, we present CoPub 5.0, a publicly available text mining system, which uses Medline abstracts to calculate robust statistics for keyword co-occurrences. CoPub was initially developed for the analysis of microarray data, but we broadened the scope by implementing new technology and new …

Onder invloed van digitalisering en internet is de afgelopen jaren de discussie over auteursrechten in het journalistieke veld opgelaaid. Verschillende aspecten spelen een rol in deze discussie. Sommigen benadrukken het belang van de online rechten van de makers en stellen dat het traditionele systeem …

The scientific literature represents a rich source for retrieval of knowledge on associations between biomedical concepts such as genes, diseases and cellular processes. A commonly used method to establish relationships between biomedical concepts from literature is co-occurrence. Apart from its use …

Phylogenetic patterns show the presence or absence of certain genes in a set of full genomes derived from different species. They can also be used to determine sets of genes that occur only in certain evolutionary branches. Previously, we presented a database named PhyloPat which allows the complete …

Throughout the years women in most countries were granted the same political rights as men. Namely, the right to vote and the right to stand for election. However, this did not automatically lead to equal participation in political decision making. It is remarkable to see that this, even though women …

Several models in data analysis are estimated by minimizing the objective function defined as the residual sum of squares between the model and the data. A necessary and sufficient condition for the existence of a least squares estimator is that the objective function attains its infimum at a unique …
