  1. 1. The value of cardiac MRI texture analysis in patients with clinically suspected myocarditis

    Master-uppsats,

    Författare :Evin Ina Papalini; [2021-05-10]
    Nyckelord :Medical physics; Myocarditis; Cardiac magnetic resonance; Texture analysis;

    Sammanfattning : Purpose: The aim of this proof-of-concept study was to assess the diagnostic value of texture analysis (TA) based on conventional balanced steady-state-free precession (bSSFP), late gadolinium enhancement (LGE) and T2-weighted cardiac magnetic resonance imaging (CMRI) in patients with clinically suspected myocarditis. Method: A retrospective cohort study was performed based on 30 patients who underwent a comprehensive CMRI due to clinically suspected myocarditis between 2013 and 2018 at the Sahlgrenska University Hospital: 10 patients with clinical signs and positive myocardial biomarkers (Troponin T, indicating myocardial injury) as well as positive CMRI findings according to Lake Louise Criteria (LLC; group 1), 10 patients with clinical signs and positive myocardial biomarkers but negative CMRI findings according to LLC (group 2), and 10 patients with clinical signs but both negative myocardial biomarkers as well as CMRI findings according to LLC (control group).

  3. 2. Study of ohmic contact formation on AlGaN/GaN heterostructures

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Kai-Hsin Wen; [2019]
    Nyckelord :ohmic contacts; wide bandgap; Ta-based; recess etch; N-vacancies;

    Sammanfattning : It is challenging to achieve low-resistive ohmic contacts to III-nitride semiconductors due to their wide bandgap. A common way to reduce the contact resistance is to recess the ohmic area prior to metallization. LÄS MER

  4. 3. Preschoolers Favour Teachable Agent’s Action over Distraction

    Master-uppsats, Lunds universitet/Kognitionsvetenskap

    Författare :Anton Axelsson; [2013]
    Nyckelord :teachable agent; attention; executive functions; theory of mind; preschooler; distractibility; eyetracking; Technology and Engineering; Social Sciences;

    Sammanfattning : Studies on teachable agents (TA) have repeatedly demonstrated their benefits in primary school pupils’ learning, but no study has yet been devised to investigate whether the same effects can be observed in preschoolers. Preschool age is an important time for development of executive functions (EF) and theory of mind (ToM), and it can be argued that preschoolers might not be able to pay enough attention to a TA due to underdevelopment of these cognitive abilities.
