Progress has been slow in defining molecular requirements for human B lymphopoiesis in part because of differences from experimental animals and also because of the lack of culture conditions that efficiently support the process. We recently found that human CD10+ lymphocytes were produced when CD34+ hematopoietic stem and progenitor cells were cultured in(More)
An approach by the IST FUTURE project to make packet based multimedia services feasible in a satellite based UMTS environment. Different QoS guaranteeing mechanisms are presented exploiting the terrestrial UMTS specification in order to achieve an integrated T-S-UMTS. The focus is set on mechanisms for the access network, while the core network is only(More)
The huge growth in wireless communication has led to a wide range of technologies each addressing a particular scenario or need. The goal of the WINNER project is to develop a single new ubiquitous radio access system concept to address the whole spectrum of mobile communications scenarios. This paper surveys the challenge of providing ubiquitous operation(More)
Increased total antigen amounts of cathepsin D in breast tissue have been reported to be associated with increased disease recurrence, more frequent metastasis, and increased mortality in breast cancer patients. In the present study, Western blotting analysis has been used for the first time to determine the relative amounts of precursor and processed forms(More)
The objective of this deliverable is to provide a comprehensive and consistent overview on the WINNER system concept work at the end of the first project phase. Concepts investigated in various WINNER work packages have been harmonized and integrated into the WINNER system concept which is described within this deliverable. To illustrate the WINNER system(More)
— The paper shows that relays as inherent technology of IMT-Advanced system can provide low delays as required for future multi-media services. The results shown prove that the proposed relaying scheme is able to keep relay requirements on the air interface and to support delay sensitive high interactive services. The analytical results are validated by(More)
