  1. 16. Fighting microbial infections with force fields: Evaluating conformational ensembles of intrinsically disordered proteins

    Författare :Stephanie Jephthah; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; force field; Monte Carlo; coarse-grained modeling; simulation; intrinsically disordered protein; histatin 5; small-angle x-ray scattering; circular dichroism; atomistic MD simulations; all-atom protein models;

    Sammanfattning : The main goal of this compilation thesis has been to investigate the conformational ensemble of the intrinsically disordered protein (IDP) histatin 5 by using a mixture of experimental and computational techniques including, but not limited to, small-angle X-ray scattering (SAXS), circular dichroism (CD) spectroscopy, atomistic molecular dynamics (MD) simulations, and coarse-grained Monte Carlo (MC) simulations. Histatin 5 is a peptide of particular interest for two reasons. LÄS MER

  3. 17. Cultivating educational research in Lao PDR : For a better future?

    Författare :Keophouthong Bounyasone; Ngouay Keosada; Lars Dahlström; Ann-Louise Silfver; Gustave Callewaert; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; action research; teacher education; globalisation; technical rationality; hidden policy ensembles; policy backlashes; context; Lao PDR; Education; Pedagogik; pedagogik; Education;

    Sammanfattning : This thesis looks at the introduction of educational action research as part of the national education reforms in Lao PDR. National policies on education emphasise concepts such as ‘education for all’ and ‘student-centred education’ taken from the globalised education reform agenda. LÄS MER

  4. 18. Hydrological Seasonal Forecasting

    Författare :Kean Foster; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrological seasonal forecasting; seasonal forecast; spring flood; multi-model ensembles; teleconnection patterns; modelling chain;

    Sammanfattning : In Sweden, almost half of the electricity produced comes from hydropower. However, the amount of water in the reservoir catchments is not evenly distributed throughout the year. During the colder months, precipitation usually falls as snow and accumulates into a snowpack. LÄS MER

  5. 19. Spatially Coupled Turbo-Like Codes

    Författare :Saeedeh Moloudi; Kommunikationsteknologi; []
    Nyckelord :;

    Sammanfattning : The focus of this thesis is on proposing and analyzing a powerful class of codes on graphs---with trellis constraints---that can simultaneously approach capacity and achieve very low error floor. In particular, we propose the concept of spatial coupling for turbo-like code (SC-TC) ensembles and investigate the impact of coupling on the performance of these codes. LÄS MER

  7. 20. Sampling from molecular unnormalized distributions with Deep Generative Models

    Författare :Juan Viguera Diez; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; machine learning; Cheminformatics; conformational sampling; generative models; drug discovery; Boltzmann generators;

    Sammanfattning : This thesis investigates how Deep Generative Models (DGMs) can address important drug discovery problems involving sampling from unnormalized distributions. It consists of two papers focusing on this challenge’s aspects: molecular design and conformational sampling. LÄS MER
