  1. 1. Train your brain : updating, transfer, and neural changes

    Författare :Erika Dahlin; Lars Nyberg; Anna Stigsdotter Neely; Torkel Klingberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cognitive training; executive functioning; transfer; fMRI; brain system; young adults; elderly; practice; neural correlates; individual differences; Experimental brain research; Experimentell hjärnforskning; Cognitive science; Kognitionsforskning; fysiologi; Physiology;

    Sammanfattning : An initial aim of this thesis was to determine whether training of a specific executive function (updating) produces improvements in performance on trained and transfer tasks, and whether the effects are maintained over time. Neural systems underlying training and transfer effects were also investigated and one question considered is whether transfer depends on general or specific neural overlap between training and transfer tasks.

  3. 2. Plant lipid transfer proteins : Evolution, expression and function

    Författare :Monika Edstam; Johan Edqvist; Kristina Blomqvist; Jenny Hagenblad; Frederica Theodoulou; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The plant non-specific lipid transfer proteins (nsLTPs) are known for the ability to transfer different lipids in vitro, but their in vivo functions have not yet been elucidated. They seem to play a role in the defense against biotic and abiotic stresses; the gene expression of nsLTPs is often upregulated when exposed to stresses. LÄS MER

  4. 3. On the Mean Square Error of Transfer Function Estimates with Applications to Control

    Författare :Svante Gunnarsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mean square error; Transfer function; Estimation; Applications;

    Sammanfattning : In this report we study the mean square error of transfer function estimates obtained by identification. The model quality is related to the use of models in regulator design, and the properties of affecting the bias part of the mean square error, both in fixed parameter control and adaptive control.

  7. 5. Structure and Function of Cytochrome c Oxidase

    Författare :Gisela Brändén; Peter Brzezinski; Mårten Wikström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytochrome c oxidase; proton pumping; proton transfer; electron transfer; X-ray crystallography; flow flash; Biochemistry; Biokemi;

    Sammanfattning : Aerobic organisms, ranging from bacteria to humans, obtain their energy through the process of respiration. Electrons from the breakdown of food are transported through the membrane-bound enzyme complexes of the respiratory chain, to the terminal acceptor molecule, oxygen. LÄS MER
