  4. 2. Cognitive control in reinforcement learning : brain structure and function

    Author : Björn C Schiffler; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Adapting behaviour according to internal or external feedback is a fundamental property of cognitive control. For example, humans tend to slow down when they make mistakes, a process called post-error slowing (PES), which has previously received extensive attention in research on response inhibition.

  5. 3. Hydrogen in nano-sized metals : Diffusion and hysteresis effects

    Author : Wen Huang; Björgvin Hjörvarsson; Max Wolff; Gavin Walker; Uppsala universitet; []
    Keywords : Hydrogen; diffusion; hysteresis; optical technique; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Metal hydrides can be used as hydrogen storage materials for fuel cells and batteries, and as sensors for detecting hydrogen gas. The use of metal hydrides for hydrogen storage can be hindered by poor kinetics and low capacity. Moreover, poor sensitivity, long recovery and response time, limit the applications of metal hydrides as hydrogen sensors. READ MORE

  6. 4. Uncovering Ocean Mixing near Rough Bathymetry : Using Broadband Acoustics

    Author : Julia C. Muchowski; Christian Stranne; Martin Jakobsson; Lars Umlauf; Lars Arneborg; Fer Ilker; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ocean mixing; diapycnal mixing; broadband acoustics; turbulence microstructure; rough bathymetry; stratified flow over obstacles; observations of turbulent mixing; Baltic Sea research; maringeologi; Marine Geology;

    Abstract : Ocean mixing related to rough bathymetry is highly dynamic and exhibits large spatial and temporal variability. Therefore, established in-situ methods as well as numerical models often lack the resolution to capture this type of mixing. In this thesis, acoustics are used to observe, map and quantify stratified mixing at unprecedented resolution. READ MORE

  7. 5. Development of new affinity proteins for neurodegenerative disorders

    Author : Linnea C. Hjelm; John Löfblom; Stefan Ståhl; Hanna Lindberg; Ylva Ivarsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein engineering; sequestrins; amyloid beta; alpha-synuclein; phage display; affibodies; blood–brain barrier; Transferrin receptor; receptor-mediated transcytosis; recombinant spider silk; Biotechnology; Bioteknologi;

    Abstract : Neurodegenerative disorders include a full spectrum of diagnoses, including dementias and other neuronal diseases, characterised by degradation of neurons in the brain occurring along with disease progression. Amongst the dementias, the most prevalent are Alzheimer’s (AD) and Parkinson’s disease (PD) that affect millions of people worldwide. READ MORE
