  1. 1. Sexual Signals and Speciation : A Study of the Pied and Collared Flycatcher

    Author : Jon Haavie; Glenn-Peter Saetre; Trevor Price; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Speciation; Sexual signals; Hybridization; Reinforcement; Song; Female preference; Sex-linkage; Biologi; Biology; Biologi;

    Abstract : Speciation is the process in which reproductive barriers evolve between populations. In this thesis I examine how sexual signals contribute to the maintenance, reinforcement or breakdown of reproductive barriers.Male pied flycatchers (Ficedula hypoleuca) and collared flycatchers (F. albicollis) differ in song and plumage traits.

  2. 2. Signals and Noise in Complex Biological Systems

    Author : Johan Rung; Erkki Brändas; Måns Ehrenberg; Uppsala universitet; []
    Keywords : Engineering physics; complex systems; computational biology; gene networks; genome-wide; stochastic resonance; microarray; diabetes; association study; transcription regulation; gene expression; Teknisk fysik;

    Abstract : In every living cell, millions of different types of molecules constantly interact and react chemically in a complex system that can adapt to fluctuating environments and extreme conditions, living to survive and reproduce itself. The information required to produce these components is stored in the genome, which is copied in each cell division and transferred and mixed with another genome from parent to child. READ MORE

  3. 3. Stimuli Generation Techniques for On-Chip Mixed-Signal Test

    Author : Shakeel Ahmad; Jerzy Dabrowski; Torkel Arnborg; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : With increased complexity of the contemporary very large integrated circuits the need for onchip test addressing not only the digital but also analog and mixed-signal RF blocks has emerged. The standard production test has become more costly and the instrumentation is pushed to its limits by the leading edge integrated circuit technologies. READ MORE

  4. 4. A Risk or a Resource? : A Study of the Swedish State’s Shifting Perception and Handling of Minority Religious Communities between 1952-2019

    Author : Linnea Lundgren; Lars Trägårdh; Annette Leis-Peters; Elisabeth Christiansson; Grace Davie; Ersta Sköndal Bräcke högskola; []
    Keywords : HUMANIORA; HUMANITIES; religion; religious diversity; faith community; state; government documents; mixed method; policy; civil society; religion-state; pluralism; religious schools; Människan i välfärdssamhället; Social välfärd med inriktning mot civilsamhället; The Individual in the Welfare Society; Social Welfare and the Civil Society;

    Abstract : In Sweden, as in many other European countries, governments and other public authorities increasingly seem to view religious communities as an important resource that should be included in welfare provision and help combat problems that societies are facing, thereby intentionally or unintentionally bringing religion back into the public arena. However, religious communities also seem to be perceived as a risk and a problem that needs to be further regulated and controlled. READ MORE

  5. 5. Dynamic control of the yeast AMPK/SNF1 pathway in response to glucose signals

    Author : Loubna Bendrioua; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AMPK; SNF1; Mig1; glucose signalling; dynamic control; mechanism; Saccharomyces cerevisiae;

    Abstract : The SNF1/AMP-activated protein kinase (AMPK) belongs to a family of energy sensors that is conserved in all eukaryotes. Activated by ATP depletion, AMPK plays a vital role in restoring the energy balance by enhancing energy-generating and damping energy-requiring processes. READ MORE
