1. 26. Spike-Based Bayesian-Hebbian Learning in Cortical and Subcortical Microcircuits

   Författare :Philip Tully; Anders Lansner; Matthias Hennig; Gordon Pipa; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayes rule; synaptic plasticity and memory modeling; intrinsic excitability; naïve Bayes classifier; spiking neural networks; Hebbian learning; neuromorphic engineering; reinforcement learning; temporal sequence learning; attractor network; Computer Science; Datalogi;

   Sammanfattning : Cortical and subcortical microcircuits are continuously modified throughout life. Despite ongoing changes these networks stubbornly maintain their functions, which persist although destabilizing synaptic and nonsynaptic mechanisms should ostensibly propel them towards runaway excitation or quiescence.

3. 27. Structural and functional studies on ribonucleotide reductase protein B2 from Escherichia coli

   Författare :Margareta Karlsson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribonucleotide reductases; Eshcerichia coli;

   Sammanfattning : Ribonucleotide reductase catalyzes the reduction of ribonucleotidesto the corresponding deoxyribonucleotides, the building blocks forDNA. The enzyme from Escherichia coli consists of two proteins.Bl and B2. Protein B2 contains two dinuclear iron centers and astable tyrosyl radical. LÄS MER

4. 28. Marine Current Energy Conversion

   Författare :Staffan Lundin; Mats Leijon; AbuBakr S. Bahaj; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marine current energy; renewable energy; turbine; energy conversion; wake; Söderfors; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : Marine currents, i.e. water currents in oceans and rivers, constitute a large renewable energy resource. This thesis presents research done on the subject of marine current energy conversion in a broad sense. LÄS MER

5. 29. Formation and Early Evolution of Planetary Systems

   Författare :Daniel Carrera; Astronomi - Genomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; planet formation; planets and satellites: dynamical evolution and stability -- planets and satellites: gaseous planets -- planets and satellites: terrestrial planets; planets and satellites: terrestrial planets;

   Sammanfattning : Over the past 20 years we have discovered that exoplanets are common in the Galaxy, and are far more diverse than anyone expected. Half of all Sun-like stars are accompanied by at least one super-Earth (a planet with a size between Earth and Neptune), many planets have very high eccentricities indicative of a dynamical origin, and a small fraction of stars are accompanied by hot Jupiters, whose origin is poorly understood.

   Sammanfattning : Reality isn’t what it appears to be. Contexts are not always clear and visible. People don’t always say what they really mean. And they don’t always mean what they say. LÄS MER
