  1. 1. Spectrum Sensing Algorithms Based on Second-Order Statistics

    Författare :Erik Axell; Erik G. Larsson; Jan-Åke Larsson; Danyo Danev; Visa Koivunen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Cognitive radio is a new concept of reusing spectrum in an opportunistic manner. Cognitive radio is motivated by recent measurements of spectrum utilization, showing unused resources in frequency, time and space. Introducing cognitive radios in a primary network inevitably creates increased interference to the primary users. LÄS MER

  2. 2. The role of nuclear membrane proteins in differentiation and chromatin organization

    Författare :Cecilia Bergqvist; Einar Hallberg; Neus Visa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nuclear membrane proteins; chromatin organization; epigenetics; differentiation; stem cells; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : The nuclear envelope, consisting of an outer and an inner nuclear membrane, surrounds the genomic material. The genomic material (chromatin) is highly structured with (transcriptionally inactive) heterochromatin mostly found in the nuclear periphery and (transcriptionally active) euchromatin mostly found in the nuclear interior.

  3. 3. The p97 ATPase and the Drosophila Proteasome : Protein Unfolding and Regulation

    Författare :Kristian Björk Grimberg; Patrick Young; Neus Visa; Lars Thelander; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proteasome; ubiquitin; p97; unfolding; regulation; RNAi screen; high-throughput screen; cnc; basic leucine zipper; transcription factors; proteasome inhibition; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : For all living systems, there is a requirement to recycle and regulate proteins. In eukaryotic organisms this is accomplished by the proteasome. The p97 ATPase is another highly conserved and essential complex present throughout the eukaryotic cell. LÄS MER

  4. 4. The exosome and the maintenance of genome integrity

    Författare :Judit Domingo Prim; Neus Visa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The RNA exosome acts on different RNA substrates and plays important roles in RNA metabolism. The fact that short non-coding RNAs are involved in the DNA damage response led us to investigate whether the exosome plays a role in DNA repair. LÄS MER

  5. 5. The RNA exosome and the maintenance of genome integrity

    Författare :Judit Domingo Prim; Neus Visa; Andrés Aguilera; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EXOSC10; RRP6; DNA damage; diRNA; DDRNA; DNA end resection; homologous recombination; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The RNA exosome is a ribonucleolytic complex that acts on different RNA substrates and plays important roles in RNA metabolism. In recent years, the synthesis and the processing of RNA have been directly linked to the integrity of the genome. LÄS MER
