  1. 41. Single-cell RNA sequencing as a tool to study panarthropod evolution

    Författare :Brenda Irene Medina Jimenez; Ralf Janssen; Graham Budd; Tatjana Haitina; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Single-cell RNA sequencing; EvoDevo; gene expression; tissue dissociation; cell capture; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Panarthropoda is a monophyletic group comprised of arthropods and lobopods, molting animals with a segmented body, paired appendages, dorsal brain, and ventral nerve cords. Evolutionary Developmental Biology (EvoDevo) is an interdisciplinary field that seeks to understand how changes in development form the basis for variations in morphology and phenotypic evolution, including the genetic network underlying these processes.

    Sammanfattning : This thesis is concerned with theoretical studies of aqueous solutions and biomolecular systems. Part of the present work is to understand equilibrium solvent and solute properties, while the other part is to study processes that occur in these solutions. LÄS MER

  5. 44. Multimode resonant X-ray scattering of free molecules

    Författare :Nina Ignatova; Victor Kimberg; Faris Gel’mukhanov; Sergey Polyutov; Hans Ågren; Piero Decleva; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray absorption spectroscopy; core-excited state; nuclear dynamic; wave-packet; resonant inelastic X-ray scattering; Franck-Condon; water; methanol; water isotopomer; pump-probe; quantum chemistry; ultrafast dissociation; Kemi; Chemistry; Fysik; Physics;

    Sammanfattning : This thesis is focused on the role that nuclear dynamics plays in the formation of X-ray absorption (XAS) and resonant inelastic X-ray scattering (RIXS) spectra of multimode free molecules. A combined approach based on ab initio electronic structure methods and quantum nuclear wave packet dynamics is applied to two systems -- water and methanol in the gas phase. LÄS MER
