  2. 2. Influence of Genes and Post-translational Modifications in the Pathogenesis of Light Chain Amyloidosis

    Författare :Stina Enqvist; Per Westermark; Robert Kisilevsky; Uppsala universitet; []
    Nyckelord :MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : Amyloid is formed when a normally soluble protein undergoes conformational changes that results in self-aggregation. The pathogenic protein in light chain amyloidosis is an immunoglobulin light chain produced by a plasma cell clone mainly in the bone marrow. LÄS MER

  3. 3. Dynamic Optimization for Agent-Based Systems and Inverse Optimal Control

    Författare :Yibei Li; Xiaoming Hu; Per Enqvist; Yishao Zhou; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Inverse optimal control; formation control; differential game; credit scoring; Matematik; Mathematics;

    Sammanfattning : This dissertation is concerned with three problems within the field of optimization for agent--based systems. Firstly, the inverse optimal control problem is investigated for the single-agent system. Given a dynamic process, the goal is to recover the quadratic cost function from the observation of optimal control sequences. LÄS MER
