  1. 16. Statistical models of TF/DNA interaction

    Författare :Aymeric Fouquier d'Herouel; Erik Aurell; Otto Berg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gene expression; regulation; transcription factor; binding motif; matrix representations; gibbs sampling; binding affinity; non-specific binding; Biological physics; Biologisk fysik;

    Sammanfattning : Gene expression is regulated in response to metabolic necessities and environmental changes throughout the life of a cell. A major part of this regulation is governed at the level of transcription, deciding whether messengers to specific genes are produced or not. LÄS MER

  4. 18. Supersymmetry vis-à-vis Observation : Dark Matter Constraints, Global Fits and Statistical Issues

    Författare :Yashar Akrami; Joakim Edsjö; Lars Bergström; Roberto Trotta; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supersymmetry; cosmology of theories beyond the Standard Model; dark matter; gamma rays; dwarf galaxies; direct detection; statistical techniques; scanning algorithms; genetic algorithms; statistical coverage; Astroparticle physics; Astropartikelfysik; Cosmology; Kosmologi; Astroparticle physics; Astropartikelfysik; teoretisk fysik; Theoretical Physics;

    Sammanfattning : Weak-scale supersymmetry is one of the most favoured theories beyond the Standard Model of particle physics that elegantly solves various theoretical and observational problems in both particle physics and cosmology. In this thesis, I describe the theoretical foundations of supersymmetry, issues that it can address and concrete supersymmetric models that are widely used in phenomenological studies. LÄS MER

  5. 19. Statistical Downscaling of Precipitation from Large-scale Atmospheric Circulation : Comparison of Methods and Climate Regions

    Författare :Fredrik Wetterhall; Sven Halldin; Chong-Yu Xu; Lars-Christer Lundin; Deliang Chen; Hans von Storch; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Statistical; Downscaling; Precipitation; Large-scale circulation; PCA; TWS; Weather pattern; Regression; Weather generator; Hydrologi; Hydrology; Hydrologi;

    Sammanfattning : A global climate change may have large impacts on water resources on regional and global scales. General circulation models (GCMs) are the most used tools to evaluate climate-change scenarios on a global scale. They are, however, insufficiently describing the effects at the local scale. LÄS MER

  7. 20. Statistical Methods for Taxon Classification and Bird Migration Phenology

    Författare :Måns Karlsson; Ola Hössjer; Jonas Knape; Benjamin Bolker; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Classification; quantile regression; phenology; statistical ornithology; L-functionals; set-valued classification; species identification; statistical ecology; multispecies modelling; matematisk statistik; Mathematical Statistics;

    Sammanfattning : The connection between ecology and statistics is deep. Methodological advancement in statistics open up new possibilities to understand the distribution of life on earth, and research questions in ecology cause new statistical methods to be developed. LÄS MER
