  1. 1. Temporal dynamics of brain plasticity : characterizing brain structural changes during skill acquisition

    Författare :Tomás Mediavilla; Daniel Marcellino; Alexandra Badea; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motor learning; brain plasticity; structural plasticity; magnetic resonance imaging; voxel-based morphometry; tractography; connectivity; motor cortex; posterior parietal cortex; cerebellum; vesicular glutamate transporter;

    Sammanfattning : Traditionally, structural plasticity in the human brain has been considered to follow a linear or asymptotic increase over the course of training. However, recent studies using structural MRI revealed transient increases in grey matter volume (GMV) with learning. LÄS MER

  3. 2. Body movement as material : Designing temporal expressions

    Författare :Linnea Bågander; Clemens Thornquist; Lise Amy Hansen; Högskolan i Borås; []
    Nyckelord :HUMANIORA; HUMANITIES; Design; body; body as material; fashion design; performing arts; temporal form; practice-led research; design methods; motion design; Textiles and Fashion Design ; Textil och mode konstnärlig ;

    Sammanfattning : Movement and temporal qualities have a significant effect on design expressions. However, in the design of dress these are often overlooked, and the static form of a positioned body is considered to be the main driver of design. This work explores the expressions of the body in motion, engaged in the interaction constituted by wearing. LÄS MER

  4. 3. Modelling calving and sliding of Svalbard outlet glaciers : Spatio-temporal changes and interactions

    Författare :Dorothée Vallot; Rickard Pettersson; Veijo Pohjola; Ken Mattsson; Tómas Jóhannesson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cryospheric science; glacier modelling; time-lapse imagery; undercutting; sliding inversion; discrete particle model; calving model; subglacial hydrology; sliding law; automatic detection method; calving events size and frequency; ocean interaction; melt water runoff; ice dynamics; ice flow model; Geovetenskap med inriktning mot naturgeografi; Earth Science with specialization in Physical Geography;

    Sammanfattning : Future sea level rise associated to global warming is one of the greatest societal and environmental challenges of tomorrow. A large part of the contribution comes from glaciers and ice sheets discharging ice and meltwater into the ocean and the recent worldwide increase is worrying. LÄS MER

  5. 4. Radar Measurements of Temporal Variation in a Boreal Forest

    Författare :Albert Monteith; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; remote sensing; temporal variation; tomography; antenna array; temporal coherence; Synthetic aperture radar SAR ;

    Sammanfattning : Synthetic aperture radar (SAR) on a satellite platform is a suitable technique for all-weather global monitoring of forest parameters such as biomass. This is important for increasing the accuracy of the global terrestrial carbon flux, the largest uncertainty in our current understanding of the Earth’s carbon cycle. LÄS MER

  7. 5. A Purkinje cell Timing Mechanism. On the Physical Basis of a Temporal Duration Memory

    Författare :Fredrik Johansson; Associativ inlärning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cerebellum; Purkinje cell; Timing; Temporal; Memory; Eyeblink conditioning; mGluR7; Kir3; GIRK;

    Sammanfattning : The standard view of neural signaling is that a neuron can influence its target cell by exciting or inhibiting it. Learning is thought to involve strengthening or weakening synaptic connections. For most behaviors, the brain must learn to produce precisely timed activity patterns. LÄS MER
