  1. 11. Decoding the language of transmission among vector-pathogen-host

    Författare :Melika Hajkazemian; S. Noushin Emami; Richard Hopkins; Stockholms universitet; []

    Sammanfattning : Vector-borne diseases account for over 17 percent of all infectious diseases and lead to more than 700,000 mortalities annually. Importantly, there is a complex interaction between infectious organisms and their host. LÄS MER

  4. 13. Theoretical Studies of Hadronic Reactions with Vector Mesons

    Författare :Carla Terschlüsen; Stefan Leupold; Stefan Scherer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Vector mesons; Effective field theories; Chiral Lagrangian; Meson-meson interactionss; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Sammanfattning : Aiming at a systematic inclusion of pseudoscalar and vector mesons as active degrees of freedom in an effective Lagrangian, studies have been performed in this thesis concerning the foundations of such an effective Lagrangian as well as tree-level and beyond-tree-level calculations. Hereby, vector mesons are described by antisymmetric tensor fields. LÄS MER

  5. 14. On Robust LPC-spectrum Coding and Vector Quantization

    Författare :Roar Hagen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robustness against channel noise; LPC-spectrum coding; vector quantization; speech coding; linear mapping of a block code;

    Sammanfattning : Digital speech coding is concerned with representing a discrete-time speech signal with as few bits per second as possible without introducing annoying artifacts in the coded speech. Many modern speech coders are based on Linear Predictive Coding (LPC) which employ a source-filter model for speech production. LÄS MER

  7. 15. Lifestyle and Genome Evolution in Vector-Borne Bacteria : A Comparison of Three Bartonella Species

    Författare :Anna Carolin Frank; Siv Andersson; Stewart Cole; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Bartonella; evolution; host-restriction; vector-borne; horizontal gene transfer; genome reduction; alpha-proteobacteria; Type-IV secretion; Biologi; Biology; Biologi;

    Sammanfattning : Bacterial genomes provide records of the molecular processes associated with emergence and evolution of different bacterial lifestyles. This thesis is based on whole-genome comparisons within the genus Bartonella, an excellent model system for studies of host- and vector-specificity and infection outcome in animal-associated bacteria.
