  1. 41. Linkage and association analysis in multiple sclerosis

    Författare :Yamei Dai; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system, which is characterized by relapsing or progressive demyelinating plaques in the brain and spinal cord. It is well established that complex genetic factors influence susceptibility to MS. LÄS MER

  3. 42. Muliple-access techniques for adaptive wireless systems

    Författare :Wei Wang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : With the growing demand for mobile content, the roles of mobile handsets have started shifting from merely communication tools to multi-media channels. This trend will push the current 3G/UMTS networks towards higher throughput, mobility and connectivity. LÄS MER

    Sammanfattning : Impact of chronic total occlusions, arterial access site and pretreatment with antiplatelet drugs on mortality in patients with ischemic heart disease: A report from the SWEDEHEART registry Background Treatment of ischemic heart disease has advanced substantially in the past half-century. However, despite these achievements the survival rates in high-income countries such as Sweden have reached a plateau in the last decade. LÄS MER

  5. 44. Multihop Wireless Networks with Advanced Antenna Systems : An Alternative for Rural Communication

    Författare :Marvin Sánchez Garache; Jens Zander; Martha Steenstrup; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multihop Wirless Networks; Advanced Antenna Systems; Multiple Access Protocols; Spatial TDMA; CSMA CA; link-scheduling; power control; variable transmission rate; Telecommunication; Telekommunikation;

    Sammanfattning : Providing access to telecommunication services in rural areas is of paramount importance for the development of any country. Since the cost is the main inhibiting factor, any technical solution for access in sparsely populated rural areas has to be reliable, efficient, and deployable at low-cost. LÄS MER

  7. 45. A study in integrating multiple biological data sources

    Författare :Vaida Jakoniené; Patrick Lambrix; Nahid Shahmehri; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; information integration; databases; bioinformatics; biological data; BioTrifu; Computer science; Datavetenskap;

    Sammanfattning : Life scientists often have to retrieve data from multiple biological data sources to solve their research problems. Although many data sources are available, they vary in content, data format, and access methods, which often vastly complicates the data retrieval process. LÄS MER
