    Sammanfattning : The aim of this prospective longitudinal multicenter study was to evaluate the health-related quality of life (HRQL) in patients with head and neck cancer at diagnosis, after one and five years in relation to tumour location, stage, sub site, treatment modality, gender and age. The first part of the study, lasting for one year, consisted of 357 patients (mean age 63 years; 72% males) that were included between 1993 and 1995. LÄS MER

    Sammanfattning : Background Prospective longitudinal studies in Alzheimer's disease (AD) that include cholinesterase inhibitor (ChEI) treatment in routine clinical settings are scarce. The patients vary in severity of the disease, clinical course, rate of progression and response to treatment. LÄS MER

  4. 18. Multicriteria optimization for managing tradeoffs in radiation therapy treatment planning

    Författare :Rasmus Bokrantz; Anders Forsgren; Karl-Heinz Küfer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; multicriteria optimization; robust optimization; Pareto optimality; Pareto surface approximation; Pareto surface navigation; intensity-modulated radiation therapy; volumetric-modulated arc therapy; intensity-modulated proton therapy; Optimering; flermålsoptimering; robust optimering; Paretooptimalitet; Paretofrontsapproximation; Paretofrontsnavigering; intensitetsmodulerad strålterapi; rotationsterapi; intensitetsmodulerad protonterapi;

    Sammanfattning : Treatment planning for radiation therapy inherently involves tradeoffs, such as between tumor control and normal tissue sparing, between time-efficiency and dose quality, and between nominal plan quality and robustness. The purpose of this thesis is to develop methods that can facilitate decision making related to such tradeoffs. LÄS MER

  5. 19. Physics-Informed Neural Networks and Machine Learning Algorithms for Sustainability Advancements in Power Systems Components

    Författare :Federica Bragone; Stefano Markidis; Kateryna Morozovska; Tor Laneryd; Michele Luvisotto; Matthias Ehrhardt; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics-Informed Neural Networks; Machine Learning; Data-Driven Methods; Circular Economy; Power Systems Components; Sustainability; Cellulose Nanofibrils; Fysikinformerade Neurala Nätverk; Maskininlärning; Datadrivna Metoder; Cirkulär Ekonomi; Kraftsystemets Komponenter; Hållbarhet; Cellulosananofibriller; Datalogi; Computer Science;

    Sammanfattning : A power system consists of several critical components necessary for providing electricity from the producers to the consumers. Monitoring the lifetime of power system components becomes vital since they are subjected to electrical currents and high temperatures, which affect their ageing. LÄS MER

  7. 20. Neuropsychological Function After Coronary Artery Bypass Grafting

    Författare :Cecilia Dautovic Bergh; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; neuropsychology; neurophysiology; Neurology; coronary artery bypass surgery; S100B; neuropsychological function; Psychology; Neurologi; neuropsykologi; neurofysiologi; Psykologi;

    Sammanfattning : Despite considerable research efforts, the incidence and mechanisms of diffuse cognitive impairment after coronary artery bypass surgery are not fully understood. The aim of the dissertation was to describe cognitive changes after coronary artery bypass grafting (CABG) and the predictors and consequences thereof. LÄS MER
