  2. 1. Theoretical and Experimental Studies of Polymer Adsorption and Polymer Mediated Interactions

    Author : Fei Xie; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte; Adsorption; Colloid; Polymer; Dispersion; Interation; Ellipsometry; Monte Carlo Simulation; Classical Density Functional Theory;

    Abstract : Polyelectrolyte adsorption and polymer mediated interactions in different colloidal polymer systems have been studied in this work. Theoretical methods and experimental techniques are combined, in order to obtain more general reliable results, as well as a deep understanding of the molecular mechanisms that are responsible for the observed behaviors.

  4. 2. Studies on vascular remodeling in acute coronary artery disease

    Author : Fei Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Atherosclerosis; unstable angina; matrix metalloproteinase; apoptosis; angiogenesis; remodeling;

    Abstract : Atherosclerosis is an arterial disease, characterized by endothelial dysfunction, vascular inflammation, and lipid accumulation in the vessel wall. Unstable coronary syndroms may be initiated by rupture of the atherosclerotic plaque, which may be caused by activation of matrix metalloproteinases (MMPs), apoptosis and angiogenesis. READ MORE

  5. 3. Computational Materials Design of Medium Mn Steels

    Author : Fei Huyan; Annika Borgenstam; Peter Hedström; Marcel Somers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Medium Mn steels (~ 3–10 mass % Mn), a new category of advanced high strength steels, attracted worldwide research interests recent years due to their excellent mechanical properties and low cost. These steels have fine microstructures and contain large fraction of metastable retained austenite (~ 30 volume %), therefore exhibit excellent strength and elongation. READ MORE

  6. 4. Learning-based Software Testing using Symbolic Constraint Solving Methods

    Author : Fei Niu; Karl Meinke; Reiner Hähnle; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Testing; Machine learning; Symbolic constraint solving; Model checking;

    Abstract : Software testing remains one of the most important but expensive approaches to ensure high-quality software today. In order to reduce the cost of testing, over the last several decades, various techniques such as formal verification and inductive learning have been used for test automation in previous research.

  7. 5. Can Parkinson’s disease be prevented? Epidemiological evidence on lifestyle factors

    Author : Fei Yang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The etiology of Parkinson’s disease (PD) is largely unknown, but epidemiological studies have provided robust evidence that environmental factors have a central role in PD pathogenesis and progression. The studies included in this thesis examined associations between several lifestyle factors and subsequent risk of PD. READ MORE
