Fibronectin (FN) is secreted as a disulfide-bonded FN dimer. Each subunit contains three types of repeating modules: FN-I, FN-II, and FN-III. The interactions of alpha5beta1 or alphav integrins with the RGD motif of FN-III repeat 10 (FN-III10) are considered an essential step in the assembly of FN fibrils. To test this hypothesis in vivo, we replaced the(More)
We present a new architecture for decentralized user modeling and briefly discuss the user model markup language USERML, the general user model ontology GUMO for the uniform interpretation of decentralized user models, and the integration of ubiquitous applications with the u2m.org user model service. The motivation is that ubiquitous evaluation of user(More)
We use semantic web technology to utilize the world wide web for a large-scale ubiquitous hybrid location model, in order to achieve shareability and extensibility. Our intention is to model location and user characteristics, in order to realize location aware applications with focus on situated user interaction and pedestrian navigation. We present the(More)
We propose an approach for using data from a social tagging application like del.icio.us as a basis for user adaptation. We discuss several algorithms for mining taxonomies of tags from tag spaces. The mined taxonomy can be used to define adaptation rules that determine how to adapt a system to a user given the user's personal tag space. The contributions(More)
We revisit the top-level ontology Gumo for the uniform management of user and context models in a semantic web environment. We discuss design decisions, while putting the focus on ontological issues. The structural integration into user model servers, especially into the U2M-UserModel&ContextService, is also presented. We show ubiquitous applications using(More)
In an Always Best Positioned (ABP) localization system the output of different localization techniques are fused together to get an even better position accuracy. Besides the information about the position of a user, his viewing or walking direction is also important. This paper describes an extension of our mobile APB system that uses RFID tags and(More)
