OBJECTIVES The European GEMSS Project is concerned with the creation of medical Grid service prototypes and their evaluation in a secure service-oriented infrastructure for distributed on demand/supercomputing. Key aspects of the GEMSS Grid middleware include negotiable QoS support for time-critical service provision, flexible support for business models,(More)
A system for the automatic segmentation of German words into morphs was developed. The main linguistic knowledge sources used by the system are a word syntax and a morph dictionary. The syntax is written in the formalism of right linear regular grammars and comprises approximately 1,400 rules describing the set of those sequences of morph classes which(More)
BACKGROUND Interim analyses are used in clinical trials in order to enable early decisions for medical, ethical, and economic reasons. However, it appears unfeasible to stop a trial during such an interim analysis. New patients will thus enter the trial while the interim analysis is ongoing. Moreover, depending on the event kinetics of the specific disease,(More)
The water and potassium content and the relative vacuolar volume (α = Vvacuole/Vcell) of mesophyll cells of the needles of healthy 21-yearold spruce trees [Picea abies (L.) Karst.] were determined. In 5-year-old needles α was 0.626 ± 0.178 (ovx ± SD). Potassium concentrations in the bulk tissue water ranged from about 65 to 105 mM. Simulations were made(More)
Adhesion of adherent cells on structured surfaces is influenced by the surface pattern given. Here, we designed a structured gold relief surface based on cell adhesion patterns we had previously observed. We analysed the geometric parameters and the overall distribution of focal adhesion kinase in focal adhesions on unstructured glass surfaces using optical(More)
The breeding biology ofApus c. caffer at the Cape is compared with that ofApus c. caffer in Southern Rhodesia, as described byBrooke (1957), and that ofApus c. streubelii in Tanganyika, as described byMoreau (1942). Apus c. caffer is not entirely dependent on Hirundinidae for nests, but also builds its nest under roofs. These swifts stay at the Cape from(More)
