DRM systems involve multiple parties such as owner, distributors and consumers. The owner issues redistribution licenses to its distributors. Distributors in turn using their received redistribution licenses can issue new redistribution licenses to other distributors and usage licenses to consumers. For rights violation detection, all newly generated licenses must be validated against the redis...

Appropriate data distribution has been found to be critical for obtaining good performance on Distributed Memory Multicomputers like the CM-5, Intel Paragon and IBM SP-1. It has also been found that some programs need to change their distributions during execution for better performance (redistribution). This work focuses on automatically generating eecient routines for redistribution. We prese...

Single-molecule pump probe (SM2P) is a novel, fluorescence-based technique that allows the study of ultrafast processes on the single-molecule level. Exploiting SM2P we have observed large variations (from 1 ps to below 100 fs) in the energy redistribution times of chemically identical molecules in the same sample. Embedding the molecules in a different matrix or changing the excitation wavelen...

Most systems of health care financing in EU member states currently include elements of income redistribution. The paper analyzes the effects of shifting this kind of redistribution to the tax system and argues that this reform could create two types of efficiency gains. On the expenditure side, it would facilitate the adoption of more incentive-compatible insurance contracts, for example throu...
