A clinical case is presented in which a new type of fiber post was used in combination with the proprietary dual-curing resin cement to bond in a wide, nonrounded root canal. The anatomic post was inserted and the relining resin photopolymerized. The anatomic post was then removed and a luting procedure was performed, as for any other translucent post. The clinical procedure was simple, and a s...

Early in the 1980s Stephen Wolfram began to work in earnest upon cellular automata. These are a class of computer model which may be visualized as a set of memory locations, each containing one bit. These bits are updated in a succession of time steps. In each step, the new value of each bit depends upon the values of neighboring bits. Wolfram particularly studied the class of automata in which...

Nanotechnology has been extensively explored in the past decade to develop a myriad of functional nanostructures to facilitate the delivery of therapeutic and imaging agents for various medical applications. Liposomes and polymeric nanoparticles represent two primary delivery vehicles that are currently under investigation. While many advantages of these two particle platforms have been disclos...

The goal of benchmarking and performance evaluation, as viewed in this paper, is to assess the performance and understand characteristics of HPC platforms and their important applications. An obvious use of the gained results is the search for machines that are best for a given purpose. Equally important uses are the creation of yardsticks for research and the anticipation of needs of future HP...

This paper builds on the collaborative work of media researchers and professionals as well as education decision makers and teachers that met in Graz, 57 December 2007, at the invitation of the Council of Europe. The purpose of the workshop was to determine the validity of media education and to verify that human rights could be an added value to such an education. Three main questions were deb...

*This is the first draft of the paper that will be the basis of the Welcome Lecture (What are advances in knowledge doing to the large industrial firm in the new economy?) on 6 June, 2002, at the DRUID Summer Conference on Industrial Dynamics of the New and Old Economy – who embraces whom?. It will subsequently be expanded into a joint paper with Nick von Tunzelmann. Comments welcome.

| We present a new approach to the problem of revising extended programs, based on the coherence theory initially advocated by Gardenfors for belief revision. Our approach resolves contradiction by removing only connict-ing information, not the believed source of it, and therefore , keeps information loss minimal. Furthermore, since there is no need of searching for problematic assumptions, as ...

We present a new type of brane inflation motivated by multikink solitonic solutions of a scalar field in five dimensions. In the thin brane limit, we analyze a nonstatic configuration in which the distance between two parallel domain walls decreases. We show that the ensuing spacetime is inflationary, both on the branes, and, for certain potentials, in the bulk. We argue that this inflationary ...

Programming is notoriously hard for novices to learn and a substantial number of learners fail in introduction to programming courses. It is not just a UK problem: a number of multi-institutional and multi-national studies reveal that the problem is well-known and is widespread. There is no general agreement about the causes or the remedies. The major factors which can be hypothesised as a caus...
