  1. 1. Mitigating Distributed Denial-of-Service Attacks: Application-defense and Network-defense Methods

    Författare :Zhang Fu; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Distributed Denial-of-Service; Network Security; Distributed Computing; System Design;

    Sammanfattning : Distributed Denial of Service (DDoS) attacks can be so powerful that theycan easily deplete the computing resources or bandwidth of the potential targets.Based on the types of the targets, DDoS attacks can be addressed in two levels:application-level and network-level. LÄS MER

  3. 2. Multifaceted Defense Against Distributed Denial of Service Attacks: Prevention, Detection, Mitigation

    Författare :Zhang Fu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data Streaming; Network Security; Overlay; Distributed Denial-of-Service; System Design; DDoS Detection; Distributed Computing;

    Sammanfattning : Distributed Denial of Service (DDoS) attacks can be so powerful that they can easily deplete the computing resources or bandwidth of the potential targets, by flooding massive packets. Internet infrastructures and network applications, including social services and communication systems for emergency management, are under the threat of the DDoS problem. LÄS MER

  4. 3. Human herpesvirus 6 infection after allogeneic stem cell transplantation

    Författare :Fu-Zhang Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Human herpesvirus 6 (HHV-6) is a lymphotropic virus mainly infecting T lymphocytes but also other types of cells. Seroepidemiological studies have shown that more than 90% of individuals older than 2 years are seropositive for HHV-6. LÄS MER

  5. 4. Making sense from nonsense and missense : pharmacological rescue of mutant tumor suppressor p53

    Författare :Meiqiongzi Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : A large fraction of human tumors carry inactivating mutations in the TP53 tumor suppressor gene. Approximately 75% of these mutations are missense mutations and around 10% are nonsense mutations. TP53 inactivation allows evasion of cell death and rapid tumor progression. LÄS MER
