  4. 2. Validation of Several Nucleoside Tracers as Proliferation Markers

    Author : Li Lu; Sven Reske; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biopharmacy; PET; cell proliferation; DNA synthesis; hydroxyurea; cimetidine; diuretic; Biofarmaci; Biopharmacy; Biofarmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Positron emission tomography (PET) is a powerful method for in vivo characterization of tumor biochemistry and clinically has been used for diagnosing and grading of malignancy. A key element in oncology is proliferation potential, a feature that is assumed to be an important indicator of tumor growth. READ MORE

  5. 3. Ab Initio Investigation of Interfacial and Grain Boundary Properties of Metals and Alloys

    Author : Changle Li; Levente Vitos; Song Lu; Hongbin Zhang; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : Phase interface (IF) and grain boundary (GB) are both common yet critical planar defects influencing the mechanical and physical properties of polycrystalline materials. Due to the complex nature of IFs and GBs in terms of structure and chemistry, determining the accurate excess energies associated with these defects is challenging for both experimental measurements and theoretical simulations.

    Abstract :  The explosive proliferation of mobile users and wireless data traffic in recent years pose imminent challenges upon wireless system design. The trendfor wireless communications becoming more complicated, decentralized andintelligent is inevitable. READ MORE

  7. 5. Time-resolved laser spectroscopic studies of atoms, ions and Molecules

    Author : Zhongshan Li; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:2000:Li;

    Abstract : Time-resolved laser spectroscopy has been performed to study the radiative properties of various microscopic systems. Using Laser-Induced Fluorescence (LIF) techniques, natural radiative lifetimes have been studied not only in neutral B, S, Ge, Ce, Pb, and in singly ionized V, Fe, Zr, Mo, La, Ce, Eu, Gd and Yb, but also in doubly ionized La, Ce, Pr, Eu, Er, Gd, Tm, Lu, and W.
