1. 6. Polyunsaturated Fatty Acids Modifying Ion Channel Voltage Gating

   Författare :Sara Börjesson; Fredrik Elinder; Klaus Benndorf; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Voltage-gated ion channels play fundamental roles in neuronal excitability and therefore dysfunctional channels can cause disease. Epilepsy is such a disease, affecting about 1% of the population and being characterized by synchronous electric activity of large groups of neurons leading to various types of seizures. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

4. 8. Static Power Reduction and Estimation in CMOS Circuits Considering Emerging Leakage Mechanisms

   Författare :Mindaugas Drazdziulis; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; subthreshold; CMOS; wake-up time; power gating; gate leakage; VLSI;

   Sammanfattning : Due to semiconductor technology advancements, the static power dissipation caused by leakage currents in CMOS circuits is growing at a much faster rate than dynamic power; the dominant power component. As a result, controlling and limiting static power becomes as crucial as controlling dynamic power. LÄS MER

5. 9. Interpolymer complexation of a polymer brush

   Författare :John Andersson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional materials; macromolecular gating; Interpolymer complex; nanopores; polymer brush; pH responsive;

   Sammanfattning : Controllable macromolecular gating between nanoscopic compartments is of high interest for single molecule studies of biological macromolecules. By definition, a good macromolecular gate should completely stop biomolecules, such as proteins, from crossing between compartments in its closed state while letting them pass in its open state.

7. 10. Generation of Ultrashort Pulses – From Femtoseconds to Attoseconds

   Författare :Maite Louisy; Atomfysik; []
   Nyckelord :Attosecond; Femtosecond; Ultrashort laser pulses; Ultrafast optics; High-order harmonic generation; extreme ultraviolet; Post-compression; Hollow-core capillary; d-scan; Optical gating; Fysicumarkivet A:2017:Louisy;

   Sammanfattning : Electronic dynamics takes place on the attosecond timescale and can thus only be studied using a tool with attosecond temporal resolution. High harmonic generation (HHG) provides coherent attosecond pulses in the extreme ultraviolet spectral region. LÄS MER
