  2. 1. Inference of Hierarchical Structure in Complex Systems

    Author : Olof Görnerup; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein evolution; Substitution groups; Modularity; Hierarchical dynamics; RNA world; Genetic code; Aggregation; Primordial evolution; Molecular evolution; Model reduction; Self-organization; Lumping; Emergence; Coarse graining;

    Abstract : Hierarchical organization is a central property of complex systems. It is even argued that a system is required to be hierarchical in order to evolve complexity within reasonable time. A hierarchy of a system is defined as the set of self-contained levels at which the system operates and can be described on. READ MORE

  4. 2. Metapopulations dynamics and sex-specific resource allocation in Silene dioica

    Author : Elisabet Peedu; Pär Ingvarsson; Barbara Giles; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Silene dioica; Skeppvik Archipelago; Metapopulation Dynamics; Population Genetic Structuring; Genetic Diversity; Gene Flow; Sex-Specific Resource Allocation; Cost of Reproduction; Life-History Theory; Sexual Dimorphism; Reproductive Effort; biology; biologi; evolutionär genetik; evolutionary genetics; ekologisk botanik; Ecological Botany;

    Abstract : Rising archipelagos provide unique settings for the study of the temporal and spatial dynamics of their biota. This offers the possibility to study the ecology and genetics of early successional processes; both between islands that differ in age and within islands when already established organisms have to keep pace with the changing environment.

  5. 3. Structural and evolutionary aspects of stochastic processes

    Author : Olof Görnerup; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Proto-cells.; Emergence; Self-organization; Coarse graining; Model reduction; Hierarchical dynamics; Pre-biotic evolution; Complexity;

    Abstract : Stochastic processes constitute a broad class of objects of central importance in complex systems. The main structural aspect of stochastic processes that is treated in this thesis is their hierarchical dynamics. READ MORE

  6. 4. Novel Multi-Scale Modeling Framework for Structure and Transport in Complex Battery Electrolytes

    Author : Rasmus Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hierarchical analysis; electrolytes; force field development; molecular dynamics; non-vehicular transport; multi-scale method; Lithium-ion batteries; genetic algorithms;

    Abstract : Affordable high energy rechargeable batteries are crucial for further electrification of the transport sector, which is necessary in order to contribute to limit our CO2 emissions to acceptable levels. While today’s lithium-ion batteries (LIBs) have indeed initiated the electrification of the transportation section successfully, electric vehicles are still expensive and typically have ranges limited to ca.

  7. 5. Hierarchical Assembly Investigations and Multiscale Characterization of Protein-based Materials : Insights from Whey Protein Nanofibrils and Recombinant Spider Silk Microspheres

    Author : Eirini Ornithopoulou; My Hedhammar; Thomas Crouzier; Christina Divne; Tim Melander Bowden; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hierarchical Assembly; Protein-based materials; Whey Protein Nanofibrils; β-Lactoglobulin; Recombinant Spider Silk; Microspheres; Biomedical Applications; Surface Biofunctionalization; Hierarkisk montering; Proteinbaserade material; Vassleprotein nanofibriller; β-Laktoglobulin; Rekombinant spindelsilke Mikrosfärer; Biomedicinska tillämpningar; Ytbiokonjugering; Biotechnology; Bioteknologi;

    Abstract : Protein-based materials, with their unique properties of combining high strength, while maintaining elasticity, and their inherent biocompatibility, hold immense potential for various applications. In order to harness these properties, we need to understand and control how protein building blocks come together to form hierarchically structured materials. READ MORE
