  2. 1. Nanowire Transistors and RF Circuits for Low-Power Applications

    Author : Karl-Magnus Persson; Institutionen för elektro- och informationsteknik; []
    Keywords : InAs; Nanowire; Metal-oxide-semiconductor field-effect transistor; MOSFET; RF; Mixer; Circuit; 1 f-noise; Simulation; Modelling;

    Abstract : The background of this thesis is related to the steadily increasing demand of higher bandwidth and lower power consumption for transmitting data. The work aims at demonstrating how new types of structures, at the nanoscale, combined with what is referred to as exotic materials, can help benefit in electronics by lowering the consumed power, possibly by an order of magnitude, compared to the industry standard, silicon (Si), used today.

  4. 2. The Genetics of Adaptation and Evolvability in Yeast

    Author : Karl Persson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Evolution; Genetics; Adaptation; Evolvability; Yeast;

    Abstract : Evolution is the hereditary change in life forms that has shaped the divergence of all organisms that inhabit planet Earth. I used the yeast Saccharomyces cerevisiae to study how adaptive evolution increases the fitness and changes the properties of experimental and natural yeast populations. READ MORE

  5. 3. Influence of cyanobacterial blooms on coastal fish recruitment

    Author : Karl-Johan Persson; Catherine Legrand; Markku Viitasalo; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; coastal fish recruitment; Akvatisk ekologi; Aquatic Ecology;

    Abstract : Cyanobacteria are the oldest oxygen-producing organisms on Earth and can be found in almost every terrestrial and aquatic habitat. Their long evolutionary history has enabled them to develop diverse adaptations in order to increase their survival in environments subjected to natural and anthropogenic changes. READ MORE

  6. 4. Parallel Numerical Procedures for the Solution of Contact-Impact Problems

    Author : Per Persson; Karl Schweizerhof; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Finite element (FE) simulations of complex problems tend to yield very large models if detailed knowledge of the problem is required. As the model becomes larger, the time needed for solving the problem increases. The solution time is even longer if contact is present in the model. READ MORE

  7. 5. Responsibility and health: explanation-based perspectives

    Author : Karl Persson de Fine Licht; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; responsibility; health; explanations; the explanation hypothesis; explanatory perspectives; priority-setting; health care; bariatric surgery;

    Abstract : There is a growing trend of holding people responsible for their lifestyle-based diseases. For example, policymakers as well as researchers have argued that medical conditions caused by smoking, overweight, or extreme sports should be given lower priority in publicly funded healthcare.
