  1. 1. Methods for the analysis and characterization of brain morphology from MRI images

    Författare :Irene Brusini; Chunliang Wang; Örjan Smedby; Eric Westman; Lars-Olof Wahlund; Jorge Cardoso; KTH; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain MRI; Image Segmentation; Machine Learning; Deep Learning; Shape Analysis; Aging; Neurodegeneration; MRT av hjärnan; Bildsegmentering; Maskininlärning; Djupinlärning; Formanalys; Åldrande; Neurodegeneration; Medical Technology; Medicinsk teknologi;

    Sammanfattning : Brain magnetic resonance imaging (MRI) is an imaging modality that produces detailed images of the brain without using any ionizing radiation. From a structural MRI scan, it is possible to extract morphological properties of different brain regions, such as their volume and shape. LÄS MER

  3. 2. Pharmacometric Investigations of Prediction Precision and Advances of Models for Composite Scale Data

    Författare :Gustaf Wellhagen; Maria C. Kjellsson; Bengt Hamrén; Per Olsson Gisleskog; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacometrics; modelling; non-linear mixed effects modelling; composite scale data; total score data; total score analysis; precision prediction; bounded integer; bounded integer model; IRT-informed total score analysis; item response theory-informed; mixed models for repeated measures; MMRM; dose-response; dose-response mixed models for repeated measures; DR-MMRM; HbA1c models; fit-for-purpose analysis; clinical trial analysis; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Clinical trials are needed to evaluate new treatments. In late-stage clinical trials, failures are mostly due to lack of efficacy. Fit-for-purpose analysis methods will likely increase the success rates and advance drug development by providing higher precision to support decisions such as go/no-go, dose selection, or sample size.

  4. 3. Neuro-immuno-regulation of inflammation in the colonic mucosa : Focus on mast cells and eosinophils in bowel disorders

    Författare :Maria Teresa Casado Bedmar; Åsa Keita; Johan D Söderholm; Marie Carlson; Melanie Gareau; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mast cells; Eosinophils; Vasoactive intestinal polypeptide; Neuro-immune; Intestinal barrier; Irritable bowel syndrome; Inflammatory bowel diseases; Ussing chamber; Advance image analysis;

    Sammanfattning : Intestinal homeostasis is key to control uptake across the mucosa and protect from harmful substances. Disturbances in the bidirectional communication between the gut and the brain are implicated in irritable bowel syndrome (IBS) and inflammatory bowel diseases (IBD), being Crohn’s disease (CD) and ulcerative colitis (UC) the two most common IBD subtypes.

  5. 4. Machine Behavior Development and Analysis using Reinforcement Learning

    Författare :Yuan Gao; Ginevra Castellano; Elin Anna Topp; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcement learning; robotics; human robot interaction; Computer Science; Datavetenskap;

    Sammanfattning : We are approaching a future where robots and humans will co-exist and co-adapt. To understand how can a robot co-adapt with humans, we need to understand and develop efficient algorithms suitable for our interactive purposes. Not only it can help us to advance the field of robotics but also it can help us to understand ourselves. LÄS MER

  7. 5. Visioner och verkligheter : Kommunikationen om företagets strategi

    Författare :Catrin Johansson; Lowe Hedman; Börje Alström; Sven Windahl; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Media and communication studies; organizational communication; organizational processes; corporate strategy; vision; mission and values; management of meaning; sense making; Balanced Scorecard; participant observation; discourse analysis; face; framing and footing; Medie- och kommunikationsvetenskap; Media and communication studies; Medie- och kommunikationsvetenskap; Medie- och kommunikationsvetenskap; Media and Communication Studies; Other social sciences;

    Sammanfattning : The starting point for this study is the question of why organizational visions are often interpreted by employees as unintelligible and insignificant. The knowledge gap in this area makes the study of communication about vision and goals both urgent and interesting. LÄS MER
