  2. 16. Hypospadias : analysis of a complex genetic disorder

    Author : Ana Maria Beleza Meireles; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : BACKGROUND: Hypospadias is a common inborn error of the male urethra that involves an abnormally placed urethral opening. Its complex etiology is largely elusive to date. Twin and familial studies highlight a genetic background in hypospadias. Environmental factors have also been identified, particularly the exposure to endocrine disrupters. READ MORE

  4. 17. Depression : genetic, epigenetic and DNA biobank studies

    Author : Philippe A Melas; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Depression is a disease that has an estimated lifetime prevalence of ~15% and a heritability of ~36%. There is support for a heterogeneous etiology of depression, which includes: a) numerous genetic loci, b) various epigenetic contributors, and c) different environmental risk factors. READ MORE

  5. 18. Generation and Optimization of Motor Behaviors in Real and Simulated Robots

    Author : Krister Wolff; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; behavior-based robotics; bipedal robots; behavior selection; evolutionary robotics; linear genetic programming; autonomous robots;

    Abstract : In this thesis, the problems of generating and optimizing motor behaviors for both simulated and real, physical robots have been investigated, using the paradigms of evolutionary robotics and behavior-based robotics. Specifically, three main topics have been considered: (1) On-line evolutionary optimization of hand-coded gaits for real, physical bipedal robots. READ MORE

  6. 19. Evolutionary Humanoids for Embodied Artificial Intelligence

    Author : Krister Wolff; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; linear genetic programming; bipedal locomotion; humanoid robotics; evolutionary algorithms;

    Abstract : The work presented in this thesis aims at investigating the potential of a proposed methodology to create a cognitive control architecture for a humanoid robot. This architecture comprises three hierarchical layers: the reactive layer, the model building layer, and the reasoning layer. READ MORE

  7. 20. Fetal programming and subsequent risks in adulthood : are the associations confounded by genetic and/or environmental factors?

    Author : Niklas Bergvall; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The fetal origins hypothesis proposes that fetal growth is inversely associated with subsequent adult disease risk. The objective of this thesis was to investigate whether familial (shared environmental and genetic) factors confound the association between birth weight and risks of hypertension, low intellectual performance, and type-2 diabetes.
