4. 2. Untangling Cortico-Striatal Circuitry and its Role in Health and Disease - A computational investigation

   Author : Jovana Belic; Jeanette Hellgren Kotaleski; Arvind Kumar; Abigail Morrison; Arthur Leblois; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cortico-striatal circuits; levodopa-induced dyskinesia; Parkinson’s disease; effective connectivity; cross-frequency coupling; corticostriatal network; network oscillations; GABAergic transmission. basal ganglia; striatum; cortex; fast spiking interneurons; medium spiny neurons; neuronal avalanches;

   Abstract : The basal ganglia (BG) play a critical role in a variety of regular motor and cognitive functions. Many brain diseases, such as Parkinson’s diseases, Huntington’s disease and dyskinesia, are directly related to malfunctions of the BG nuclei. READ MORE

5. 3. A Novel Oil-immersed Medium Frequency Transformer for Offshore HVDC Wind Farms

   Author : Mohammad Kharezy; Per Olof Hedekvist; Yuriu Serdyuk; Thomas Hammarström; Karsten Backhaus; RISE; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; prototype design methodology; finite element analysis; HVDC insulation design; medium frequency transformer; Wind energy; DC-DC power converters;

   Abstract : In this project, a design of an oil type medium frequency transformer for offshore wind farm applications is proposed. The design is intended for applications when series coupling of the output of the DC/DC converters of the wind turbine on their secondary side is done to achieve a cost-effective high voltage solution for collecting energy from offshore wind parks.

6. 4. VO2-based Thermochromic and Nanothermochromic Materials for Energy-Efficient Windows : Computational and Experimental Studies

   Author : Shuyi Li; Claes-Göran Granqvist; Gunnar Niklasson; Ivan Parkin; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; VO2; thermochromism; nanothermochromics; energy efficient windows; optical modeling; effective medium theory; thin film characterization; doping;

   Abstract : VO2-based films are thermochromic and exhibit high or low infrared transmittance when the temperature is below or above a critical temperature. The thermochromic switching is passive and reversible, and therefore VO2 based films are promising for energy-efficient window appli­cations. READ MORE
