  1. 1. Multicarrier modulation : duplexing design and interference/distortion mitigation

    Författare :Rickard Nilsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : Aspects of modern communication systems is the overall theme of this thesis with emphasis placed on multicarrier modulation. The work considers four facets of such systems; namely duplexing design, interference mitigation, channel estimation and multiuser detection. LÄS MER

  3. 2. Membrane Stress and the Role of GYF Domain Proteins

    Författare :Alexander Georgiev; Åke Wieslander; Hana Sychrova; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SYH1; SMY2; YPT6; RIC1; MYR1; processing bodies; vesicular trafficking; lipid bilayer; budding yeast; GYF; membrane stress; mRNA decay; Saccharomyces cerevisiae; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Intracellular membrane trafficking is regulated by a large number of protein complexes and lipids. Blocking of trafficking disrupts normal membrane dynamics and causes membrane stress. LÄS MER

  4. 3. Functionalization and processing of porous powders into hierarchically porous monoliths

    Författare :Petr Vasiliev; Lennart Bergström; Yoshio Sakka; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Porous; zeolite; hierarchical; monolith; nanoparticle; functionalization; amorphization; PCP; SPS; pulsed current processing; spark plasma sintering.; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Inorganic porous materials are widely used in a number of applications, where is a need to functionalize and produce materials with a multiscale porosity. The first part of the thesis describes how a novel and facile powder processing approach, using pulsed current processing (PCP) or, as it is commonly called, spark plasma sintering (SPS), has been employed to produce mechanically stable, hierarchically porous bodies from different porous powders.

  5. 4. How hands shape the mind : The P400 as an index of manual actions and gesture perception

    Författare :Marta Bakker; Gustaf Gredebäck; Amy Needham; Uppsala universitet; []
    Nyckelord :goal-directed actions; action processing; EEG; ERP; P400; gestures; grasping; embodiment; social development; give-me gesture; dynamic system theory; Psychology; Psykologi;

    Sammanfattning : Being able to perform and understand actions is crucial for proper functioning in the social world. From birth, we use our bodies to act and to promote learning about ourselves, our environment and other people’s actions and intentions. Our mind is embodied; thus, our actions play a crucial role in cognitive and social development. LÄS MER

  7. 5. mRNA degradation factors as regulators of the gene expression in Saccharomyces cerevisiae

    Författare :Mridula Muppavarapu; Tracy Nissan; Per Sunnerhagen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mRNA decapping; mRNA degradation; Pat1; Edc3; Lsm4; Lsm1-7; P bodies; Dcp2; Transcription; Ribosome biogenesis; Exosome.; molekylärbiologi; Molecular Biology;

    Sammanfattning : Messenger RNA degradation is crucial for the regulation of eukaryotic gene expression. It not only modulates the basal mRNA levels but also functions as a quality control system, thereby controlling the availability of mRNA for protein synthesis. LÄS MER
