  2. 1. Deciphering Carbohydrate Structure : From NMR Chemical Shifts to Conformational Analysis

    Author : Kevin M. Dorst; Göran Widmalm; Martina Delbianco; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR chemical shift prediction; Structural elucidation; Conformational studies; NMR spectroscopy; MD simulations; Organic Chemistry; organisk kemi;

    Abstract : Carbohydrates are ubiquitous in nature and exhibit a multitude of roles. Besides nucleic and amino acids, they can be regarded as the third alphabet of life. They are used as energy source to fuel the cells, as structural building blocks and play a key role in cellular recognition processes. READ MORE

  5. 3. Generalization under Model Mismatch and Distributed Learning

    Author : Martin Hellkvist; Ayca Özcelikkale; Anders Ahlén; Martin Jaggi; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine learning; Signal processing; Generalization error; Training error; Double-descent; Double descent; Distributed learning; Distributed optimization; Learning over networks; Model mismatch; Model misspecification; Fake features; Missing features; linear regression; regularization; Machine learning; Maskininlärning;

    Abstract : Machine learning models are typically configured by minimizing the training error over a given training dataset. On the other hand, the main objective is to obtain models that can generalize, i.e., perform well on data unseen during training. READ MORE

  6. 4. Robust optimization of radiation therapy accounting for geometric uncertainty

    Author : Albin Fredriksson; Anders Forsgren; Timothy C. Y. Chan; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optimization; intensity-modulated proton therapy; uncertainty; robust planning; setup error; range error; intensity-modulated radiation therapy; multicriteria optimization;

    Abstract : Geometric errors may compromise the quality of radiation therapy treatments. Optimization methods that account for errors can reduce their effects.The first paper of this thesis introduces minimax optimization to account for systematic range and setup errors in intensity-modulated proton therapy.

  7. 5. Sensitivity, Noise and Detection of Enzyme Inhibition in Progress Curves

    Author : Omar Gutierrez Arenas; Helena Danielson; Athel Cornish-Bowden; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Progress curves; limit of detection; Z -factor; primary screening; enzyme inhibition; error structure; sensitivity analysis; High-throughput screning; Biokemi;

    Abstract : Starting with the development of an enzymatic assay, where an enzyme in solution hydrolysed a solid-phase bound peptide, a model for the kinetics of enzyme action was introduced. This model allowed the estimation of kinetic parameters and enzyme activity for a system that has the peculiarity of not being saturable with the substrate, but with the enzyme. READ MORE
