PIDD (p53-induced protein with a death domain [DD]), together with the bipartite adapter protein RAIDD (receptor-interacting protein-associated ICH-1/CED-3 homologous protein with a DD), is implicated in the activation of pro-caspase-2 in a high molecular weight complex called the PIDDosome during apoptosis induction after DNA damage. To investigate the(More)
Virtual routers are software entities, i.e. user space processes, emulating IP routers on one or several (Linux) computers. Virtual routers can be used for both networking research and education. In contrast to simulation, virtual routers process packets in real-time and the virtual router code is similar to code in real routers. In the case of research,(More)
With the grown popularity of the Internet and the increasing use of business and multimedia applications the users' demand for higher and more predictable quality of service has risen. A first improvement to offer better than best-effort services was made by the development of the integrated services architecture and the RSVP protocol. But this approach(More)
— Distributed systems such as peer-to-peer networks and distributed servers can optimize their performance by adapting to the end-to-end QoS of the underlying network. End-to-end measurements are an important basis for such adaptivity. Although most applications measure similar properties of the network, the measurements are mostly done in(More)
Setting up experimental networks of a sufficient size is a crucial element for the development of communication services. Unfortunately, the required equipment, like routers and hosts, is expensive and its availability is limited. On the other hand, simulations often lack interoperability to real systems and scalability, which limits the scope and the(More)
Behavioral evidence suggests that the use of implicitly learned spatial contexts for improved visual search may depend on visual working memory resources. Working memory may be involved in contextual cueing in different ways: (1) for keeping implicitly learned working memory contents available during search or (2) for the capture of attention by contexts(More)
In the contextual cueing paradigm, incidental visual learning of repeated distractor configurations leads to faster search times in repeated compared to new displays. This contextual cueing is closely linked to the visual exploration of the search arrays as indicated by fewer fixations and more efficient scan paths in repeated search arrays. Here, we(More)
Active networks can provide lightweight solutions for network management-related tasks. Specific requirements for these tasks have to be met, while at the same time several issues crucial for active networks can be solved rather easily. A system addressing especially network management was developed and implemented. It provides a flexible environment for(More)
