  2. 21. Electromagnetic Field Induced Out-of-Equilibrium Structural Dynamics in Protein Crystals: From Picoseconds to Milliseconds

    Author : Viktor Ahlberg Gagnér; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Terahertz radiation; low frequency vibrations; B-factors; ADP tensor; bovine trypsin; FemtoMAX; resampling; femtosecond structural dynamics; millisecond structural dynamics; LCLS; displacements; distances; photosynthetic reaction center;

    Abstract : Light-induced interactions in biomolecules are strongly varying over different model systems. Most amino acids and proteins absorb ultraviolet light, but only a few with specialised chromophores or fluorophores, are able to absorb light in the visible spectrum. READ MORE

  4. 22. Input Estimation in Structural Dynamics

    Author : Lars Nordström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensitivity analysis; dynamic programming; input estimation; load identification; ill-posedness; regularization; indirect force measurement; inverse problems;

    Abstract : Knowledge of time-varying excitation is of importance in the design of a wide range of engineering applications, from spacecraft and processing plants to electronic circuits. Regardless of the actual application or underlying physics, the expected input will play a key role in the determination of adequate system properties and parameters. READ MORE

  5. 23. Structural and Biochemical Studies of Antibiotic Resistance and Ribosomal Frameshifting

    Author : Yang Chen; Maria Selmer; Dominique Fourmy; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein synthesis; elongation; elongation factor G; fusidic acid; antibiotic resistance; aminoglycoside adenyltransferase; ribosomal frameshifting; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Abstract : Protein synthesis, translation, performed by the ribosome, is a fundamental process of life and one of the main targets of antibacterial drugs. This thesis provides structural and biochemical understanding of three aspects of bacterial translation.Elongation factor G (EF-G) is the target for the antibiotic fusidic acid (FA). READ MORE
