Ontologies are fundamental tools used with different purposes and with different modalities in different areas and communities. To guarantee the right level of quality, the most widely used ontologies are man-made. However, developing and maintaining them turns out to be extremely time-consuming. For this reason, there are approaches aiming at their automatic construction where ontologies are i...

The regeneration of an active semi-synthetic aequorin, from apoaequorin produced in cells and a coelenterazine analogue, is a key step in measuring Ca2+ in the cells. The relative rates of the regeneration of semi-synthetic aequorins from apoaequorin and 28 synthetic coelenterazine analogues were compared. The results indicated that the rate is strongly influenced by the analogues used. The reg...

We present ongoing work on the Semantic Information Retrieval Engine (SIREn), an “entity retrieval system” specifically designed to meet the requirements of indexing and searching a large amount of semi-structured data, e.g. the entire Web of Data. SIREn supports efficient full text search with semi-structural queries and exhibits a concise index, constant time updates and inherits Information ...

Using data from Germany, we examine if month of birth influences survival up to age 105. Since age reporting at the highest ages is notoriously unreliable we draw on age-validated information from a huge age validation project of 1487 alleged German semi-supercentenarians aged 105+. We use month of birth as an exogenous indicator for seasonal changes in the environment around the time of birth....

We point out that dissociation of J/Ψ by partons (mostly gluons) produced in semi-hard nucleon-nucleon sub-collisions may explain at least a part of the spectacular J/Ψ suppression observed recently by the NA-50 Collaboration in Pb-Pb interactions at the CERN-SPS.Our arguments are based on a model in which individual nucleon-nucleon interactions in heavy ion collisions are harder than interacti...

PURPOSE We isolated an autosomal semi-dominant cataract from our inbred SHR/OlaIpcv rat colony. Heterozygotes express pulverulent cataract with smaller eyes; homozygotes express marked microphthalmia with hypoplastic lens. We call this mutation Dca (for dominant cataract). In this study, we focus on the identification of the responsible gene. METHODS We performed linkage mapping using 93 F2(S...

Motion is ubiquitous in the physical world, yet its study is much less developed than that of another common physical modality, namely shape. While we have several standardized mathematical shape descriptions, and even entire disciplines devoted to that area–such as Computer-Aided Geometric Design (CAGD)—the state of formal motion descriptions is still in flux. This in part because motion descr...
