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

    Author : Fei Xie; Teoretisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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.

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

    Author : Fei Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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

  3. 3. Computational Materials Design of Medium Mn Steels

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

  4. 4. Design, fabrication and characterization of plasmonic components based on silicon nanowire platform

    Author : Fei Lou; Lech Wosinski; Lars Thylén; Sebastian Lourdudoss; Anatoly Zayats; KTH; []
    Keywords : Planar integrated circuit; silicon photonics; plasmonics; subwavelength; directional coupler; polarization beam splitter; disk resonator; ring resonator; finite-difference time-domain; photonic crystal; electro-optic polymer; Purcell factor.;

    Abstract : Optical interconnects based on CMOS compatible photonic integrated circuits are regarded as a promising technique to tackle the issues traditional electronics faces, such as limited bandwidth, latency, vast energy consumption and so on. In recent years, plasmonic integrated components have gained great attentions due to the properties of nano-scale confinement, which may potentially bridge the size mismatch between photonic and electronic circuits.

  5. 5. Learning-based Software Testing using Symbolic Constraint Solving Methods

    Author : Fei Niu; Karl Meinke; Reiner Hähnle; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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.
