  1. 6. Multiscale Stochastic Simulation of Reaction-Transport Processes : Applications in Molecular Systems Biology

    Författare :Andreas Hellander; Per Lötstedt; Sverker Holmgren; Samuel Isaacson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stochastic simulation; chemical master equation; reaction-diffusion master equation; unstructured mesh; active transport; hybrid methods; URDME; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : Quantitative descriptions of reaction kinetics formulated at the stochastic mesoscopic level are frequently used to study various aspects of regulation and control in models of cellular control systems. For this type of systems, numerical simulation offers a variety of challenges caused by the high dimensionality of the problem and the multiscale properties often displayed by the biochemical model.

  2. 7. Computational Ecotoxicology

    Författare :Sergio Manzetti; David Van der Spoel; Janez Mavri; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pollutants; simulation; molecular; dynamic; quantum; chemistry; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Human society has progressed by polluting ecosystems since at least the early industrial revolution. Large amounts of harmful chemical compounds have been dispersed in soils, seas, ground waters and wildlife habitats by industrial and anthropomorphic activities over the last two centuries, leading to a persistent toxicological load on the environment.

  3. 8. Computational prediction of receptor-ligand binding affinity in drug discovery

    Författare :John Marelius; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; computer-aided ligand design; molecular dynamics simulation; linear interaction energy; free energy perturbation; scoring function; dihydrofolate reductase; thrombin; serine proteases; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; Molecular Biotechnology; molekylär bioteknik avd f jonfysik ;

    Sammanfattning : The evaluation of inhibition constants or, more generally, receptor-ligand binding affinities is a crucial part of the drug discovery process. Chemical synthesis and affinity screening is only affordable for a limited number of compounds. This makes computational methods to predict binding affinities of candidate ligands highly desirable.

  4. 9. Stochastic Simulation of Reaction-Diffusion Processes

    Författare :Stefan Hellander; Per Lötstedt; Johan Elf; Koichi Takahashi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; stochastic simulation; microscale; mesoscale; Smoluchowski s equation; hybrid methods; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Sammanfattning : Numerical simulation methods have become an important tool in the study of chemical reaction networks in living cells. Many systems can, with high accuracy, be modeled by deterministic ordinary differential equations, but other systems require a more detailed level of modeling. LÄS MER

  5. 10. Plasticization of Biobased Polymers: A Combined Experimental and Simulation Approach
