  1. 11. Definition of axonal injury tolerances across scales : A computational multiscale approach

    Författare :Annaclaudia Montanino; Svein Kleiven; Alessandra Villa; Xiaogai Li; Kacy Cullen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traumatic Brain Injury; Axonal Injury; Mechanoporation; Multiscale;

    Sammanfattning : Traumatic brain injury (TBI) is today regarded as a global health challenge. Revealing how external mechanical loads translate into tissue and cellular damage is necessary, not only for the development of better preventive measures, but also for the definition of treatments that could spare the patients from suffering TBI's devastating consequences.

  3. 12. From Multiple Scale Modeling to Multiscale-Modeling

    Författare :Fabian Årén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-scale modeling; AIMD; DFT; MD; lithium-ion batteries; electrolytes; machine learning;

    Sammanfattning : To power a sustainable future, interest in battery research and technology is at an all time high. In order to enable a transition to green tech many applications, such as the automotive industry, is in need of higher power densities, energy densities, longer life-times, and safer batteries.

  4. 13. Active Memory Processing on Multiple Time-scales in Simulated Cortical Networks with Hebbian Plasticity

    Författare :Florian Fiebig; Anders Lansner; Tim Vogels; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Working memory; Long-term memory; consolidation; spiking; neural network; BCPNN; cortical microcircuit; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics; Biological Physics; Biologisk fysik;

    Sammanfattning : This thesis examines declarative memory function, and its underlying neural activity and mechanisms in simulated cortical networks. The included simulation models utilize and synthesize proposed universal computational principles of the brain, such as the modularity of cortical circuit organization, attractor network theory, and Hebbian synaptic plasticity, along with selected biophysical detail from the involved brain areas to implement functional models of known cortical memory systems.

  5. 14. Tailoring the magnetic order in mesoscopic spin systems

    Författare :Henry Stopfel; Vassilios Kapaklis; Hjörvarsson Björgvin; Unnar Arnalds; John Cumings; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; artificial spin ice; magnetic nano-structures; mesoscopic spin systems; mesospins; model systems; Shakti; Saint George; interaction modifier; engineering of energy-landscape; multiple energy-scales; Fysik; Physics;

    Sammanfattning : Mesoscopic spin systems can be designed and fabricated using modern nano-fabrication techniques. These systems can contain large numbers of patterned ferromagnetic elements, for which the shape will generally determine their effective mesospin dimensionality. LÄS MER

  7. 15. The Impact of Multiple Drivers on Marine Systems : Novel approaches for studying structural changes

    Författare :Johanna Yletyinen; Thorsten Blenckner; Örjan Bodin; Erik Bonsdorff; Daniel Stouffer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; naturresurshushållning; Natural Resources Management;

    Sammanfattning : Human action is transforming the species composition, biogeochemistry and habitats of the world’s oceans at unprecedented rates. The cumulative effect of natural and anthropogenic drivers is challenging to measure, in part due to indirect effects and the complexity of marine systems. LÄS MER
