  4. 2. High Voltage DC-biased Oil Type Medium Frequency Transformer; A Green Solution for Series DC Wind Park Concept

    Author : Mohammad Kharezy; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High voltage DC; Insulation design; Offshore wind farm; Leakage inductance; High power isolated DC DC converter; Dual active bridge; Medium-frequency power transformer; Parasitic capacitance; HVDC;

    Abstract : The electric energy generated by remote offshore wind parks is transported to the consumers using high voltage submarine cables. On the generation site, such transmissions are realized today by collecting the energy produced by several wind turbines in a bulky and expensive transformer placed on a dedicated platform.

  5. 3. Gating and modulation mechanism of voltage gated sodium channels

    Author : Koushik Choudhury; Lucie Delemotte; Erik Lindahl; Philip Biggin; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Voltage gated sodium channels; Molecular dynamics simulation; π-helix; open state; Biologisk fysik; Biological Physics;

    Abstract : Voltage-gated sodium channels (Nav channels) play an essential role in nerve impulse conduction in excitable cells. Thus, these channels are involved in several neurological and muscular disorders. Understanding their mechanism of functioning  is essential for designing drugs targeting them. READ MORE

  6. 4. Transport Properties of Superconducting d-wave junctions

    Author : Tomas Löfwander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : At surfaces and interfaces of d-wave superconductors, quasiparticle bound states with zero energy, midgap states (MGS), are necessarily formed as a consequence of the sign change of the d-wave order parameter upon 90° rotation. The MGS can never exist at s-wave superconductor surfaces and are therefore true fingerprints of unconventional superconductivity. READ MORE

  7. 5. Adiabatic Andreev Levels Under Irradiation - Coherent Dynamics and Dephasing

    Author : Niklas I:son Lundin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A study of the Andreev level current through a weakly voltage-biased single-mode superconducting quantum point contact under microwave irradiation is presented. The applied microwave field induces resonant transitions between the current carrying Andreev states localized to the contact region, which results in an increase of the dc subgap current by several orders of magnitude.
