  2. 1. Computational Models in Deep Brain Stimulation : Patient‐Specific Simulations, Tractography, and Group Analysis

    Author : Teresa Nordin; Karin Wårdell; Simone Hemm-Ode; Johannes D. Johansson; Harith Akram; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anisotropy; Deep brain stimulation DBS ; Finite element method FEM ; Patient‐specific simulation; Probabilistic stimulation maps PSM ; Tractography;

    Abstract : Deep brain stimulation (DBS) is an established method for symptom relief in movement disorders like Parkinson’s disease, essential tremor (ET), and dystonia. The therapy is based on implanting an electrode with four contacts in the deep brain structures where it provides electrical stimulation, mainly impacting the nerve tracts. READ MORE

  4. 2. Structure and properties of Vasa oak

    Author : Jonas Ljungdahl; Lars Berglund; Magnus Burman; Per Hoffmann; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oak; archaeological wood; European oak; transverse anisotropy; Materials science; Teknisk materialvetenskap;

    Abstract : The Vasa ship is not adequately supported. Measurements of the hull show that the ship deforms and rotate towards the port side. In addition, damages on the hull at support areas have been observed. The damages are due to high compressive loads. READ MORE

  5. 3. Anomaly and Topology : On the axial anomaly, domain wall dynamics, and local topological markers in quantum matter

    Author : Julia D. Hannukainen; Jens H. Bardarson; Adolfo G. Grushin; Teemu Ojanen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chiral anomaly; axial anomaly; topological phases of matter; Weyl semimetals; magnetic domain walls; local topological markers;

    Abstract : Chiral anomalies and topological phases of matter form the basis of the research presented in this dissertation. The chiral anomaly is considered both in the context of magnetic Weyl semimetals and in the context of non-Hermitian Dirac actions. READ MORE

  6. 4. Spin Dynamics and Magnetic Multilayers

    Author : Björn Skubic; Olle Eriksson; Lars Nordström; Mark D. Stiles; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; magnetism; electronic structure; density functional theory; spin dynamics; spin-transfer torque; spin-density wave; multilayer; interface structure; Fysik;

    Abstract : Theoretical studies based on first-principles theory are presented for a number of different magnetic systems. The first part of the thesis concerns spin dynamics and the second part concerns properties of magnetic multilayers. The theoretical treatment is based on electronic structure calculations performed by means of density functional theory. READ MORE
