  1. 1. Techniques to Reduce Inefficiencies in Hardware Transactional Memory Systems

    Författare :Mridha Mohammad Waliullah; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intermediate checkpoint; conflicting address prediction; Bloom filter; conflict resolution; multiprocessor; speculative buffer overflow; parallel programming; 5C model for cache-misses; transactional memory; conflict classification; starvation;

    Sammanfattning : The recent trend of multicore CPUs pushes for major changes in software development. Traditional single-threaded applications can no longer get a sustainable performance boost from this new generation of CPUs that consist of multiple processors (cores). LÄS MER

  3. 2. Molecular aspects of cellular radiosensitivity in small cell lung carcinoma

    Författare :Florin Sirzén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :lung carcinoma; radiosensitivity; DNA double-strand breaks; DNA-dependent protein kinase; cell cycle checkpoints; apoptosis;

    Sammanfattning : To clarify some important molecular aspects of radiosensitivity (RS) in small cell (SCLC) compared with non small cell (NSCLC) lung carcinoma, five studies focusing on DNA damage repair, cell cycle checkpoints and apoptosis were performed. As repair of DNA double-strand breaks (DNA dsb), a critical DNA lesion, may be an important determinant of cellular RS, induction and rejoining of DNA dsb were studied using pulsed field gel electrophoresis in a radiosensitive SCLC line, U-1285 and a radioresistant NSCLC line, U-1810 (paper I).

  4. 3. Biogenesis of the bc1 complex in mitochondria

    Författare :Katharina Stephan; Martin Ott; Daniel Daley; Erika Fernandez-Vizarra; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Respiratory chain; bc1 complex assembly; mitochondrial protein biogenesis; molecular biology; yeast; Biochemistry; biokemi;

    Sammanfattning : Mitochondria perform a variety of tasks, but the function they are most prominent for is the energy conversion to form ATP, the universal energy equivalent of the cell. The majority of this ATP is created by the oxidative phosphorylation system, consisting of the respiratory chain and the ATP synthase. LÄS MER

  5. 4. Fault Tolerance for Real-Time Systems: Analysis and Optimization of Roll-back Recovery with Checkpointing

    Författare :Dimitar Nikolov; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft errors; fault tolerance; real-time systems; checkpointing; reliability;

    Sammanfattning : Increasing soft error rates in recent semiconductor technologies enforce the usage of fault tolerance. While fault tolerance enables correct operation in the presence of soft errors, it usually introduces a time overhead. LÄS MER
