  2. 1. The link between brain size, cognitive ability, mate choice and sexual behaviour in the guppy (Poecilia reticulata)

    Author : Alberto Corral López; Niclas Kolm; Janette Boughman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sexual selection; artificial selection; brain evolution; optomotor test; decision-making; discrimination; assessment; optimal decisions; rational choice; behavioural flexibility; expensive tissue; predation; sex ratio; OSR; maintenance of variation; etologi; Ethology;

    Abstract : Competition over access for mates has led to the evolution of many striking examples of morphological traits and behaviour in animals. The rapid development of the sexual selection field in recent decades have dramatically advanced our understanding of what traits make individuals more successful in attracting mates and how preferences for mates evolve over time.

  4. 2. Evaluation of Furnishes for Tissue Manufacturing

    Author : Johan Kullander; Lars Nilsson; Christophe Barbier; Thad Maloney; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : Water removal on a tissue machine becomes progressively more difficult and expensive in each successive zone. Since a big part of the cost is allocated to the drying section, improved water removal in the wet end may lead to huge savings in the manufacturing process. READ MORE

  5. 3. Robust and Efficient Cell-Based Models of Tissue Mechanics

    Author : Sonja Mathias; Andreas Hellander; Ruth Baker; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cell-based model; numerical methods; time integration; adaptivity; GPU acceleration; cell mechanics; embryonic development; cartilage formation; Beräkningsvetenskap; Scientific Computing;

    Abstract : Cell-based models of tissue mechanics have become an important tool in cancer research and developmental biology. Complementary to wet-lab experiments, they allow for cost-efficient in-silico evaluation of mechanisms not easily probed in the lab. READ MORE

  6. 4. Thinking in water : Brain size evolution in Cichlidae and Syngnathidae

    Author : Masahito Tsuboi; Niclas Kolm; Andrew Iwaniuk; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; brain evolution; phylogenetic comparative method; the expensive tissue hypothesis; cichlid; pipefish; seahorse; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : Brain size varies greatly among vertebrates. It has been proposed that the diversity of brain size is produced and maintained through a balance of adaptations to different types and levels of cognitive ability and constraints for adaptive evolution. READ MORE

  7. 5. The Spatial Context – through the lens of method development

    Author : Linda Kvastad; Joakim Lundeberg; Lars Feuk; KTH; []
    Keywords : RNA; RNA-sequencing; transcriptomics; spatial transcriptomics; single cells; pediatric brain tumors; Spatial RIN; Bioteknologi; Biotechnology;

    Abstract : In the present moment of time, we find ourselves in a period where the advancement of genomic tools is progressing at a fast pace. Of particular interest for this thesis is the study of gene activity. READ MORE
