  1. 1. Continuous-Time Delta-Sigma Modulators for Wireless Communication

    Författare :Mattias Andersson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; return-to-zero; A D converter; loop delay; delta-sigma; ADC; CMOS; STF; continuous-time; sigma; delta; filtering; CT; RZ;

    Sammanfattning : The ever increasing data rates in wireless communication require analog to digital converters (ADCs) with greater requirements on speed and accuracy, while being power efficient to prolong battery life. This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC. LÄS MER

  3. 2. Molecular Probing of Local Protein-Protein Interactions : Studies of the tissue factor, factor VIIa complex formation

    Författare :Maria Österlund; Mikael Oliveberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Protein-protein interactions are intrinsic to virtually all cellular processes. However, very little is known about the dynamics of the formation of protein complexes or the order of events that direct the association between two protein molecules (the association pathway), especially when different interacting surfaces are involved.

  4. 3. Tissue Factor in Complex : Studies of interactions between blood coagulation proteins

    Författare :Karin Carlsson; Magdalena Svensson; Susanne Wisén; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Many biological processes rely on specific protein-protein interactions, for example immune responses, cell signaling, transcription, and blood coagulation. Blood coagulation is initiated when a vessel wall is damaged, exposing tissue factor (TF) to the circulating factor VII/factor VIIa (FVII/FVIIa) which results in the formation of the TF:FVIIa complex and thereby the initiation of blood coagulation.

  5. 4. The Location and Variability of Southern ocean Fronts

    Författare :Robert M. Graham; Agatha M. de Boer; Jonas Nycander; Qiong Zhang; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The location of fronts has a direct influence on both the physical and biological processes in the Southern Ocean. Moreover, the Subtropical Front (STF) is believed play a key role in the global climate system. LÄS MER

  7. 5. Studies of Local Interactions between and within Proteins using Site-Directed Labeling Techniques

    Författare :Rikard Owenius; Lawrence J. Berliner; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Proteins are essential participants in virtually all cellular processes. The key to the understanding of the function of a certain protein is a detailed knowledge about its atomic three-dimensional structure. LÄS MER
