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

    University essay from

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

    Abstract : 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 whounderwent a comprehensive CMRI due to clinically suspected myocarditisbetween 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).

  2. 2. The effects of political uncertainty on options: An empirical study of S&P 500, Euro Stoxx 50, and S&P sectors around political events

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Gabriel Wannes; Nihat Anwar; [2021]
    Keywords : Political uncertainty; Options; Implied volatility; Sectors;

    Abstract : We study options spanning political events and examine whether a price premium, associated with the political uncertainty from events, exists. First, we use recent data and replicate parts of Kelly, Pastor, and Veronesi (2016) by analysing how the price risk, variance risk, and tail risk associated with political events, affect equity options on the S&P 500 and Euro Stoxx 50 indices.

  3. 3. Cyclical consumption and the aggregate stock market: Evidence from the Nordic countries

    University essay from Jönköping University/IHH, Företagsekonomi; Jönköping University/IHH, Företagsekonomi

    Author : Sasu Huttunen; Govert Looije; [2021]
    Keywords : Cyclical consumption; Aggregate stock market; Nordic countries; Out-of-Sample Predictability;

    Abstract : Researchers have dedicated considerable work to explaining components to excess stock market returns. Recently, Atanasov et al. (2020) managed to explain some of this variance in the US stock markets with a cyclical consumption variable. READ MORE

  4. 4. Is there a relationship between spatial orientation ability, and field of study and gender?

    University essay from Umeå universitet/Institutionen för psykologi

    Author : Teodora Neagu; [2021]
    Keywords : spatial ability; spatial orientation; gender; STEM; spatial förmåga; spatial orientering; kön; STEM; naturvetenskap;

    Abstract : Spatial ability has been studied in relation to education and gender previously, concluding that men outperform women in any field of study in spatial tasks and test batteries. For that reason, the present study aims to confirm such differences through a spatial orientation task and the Santa Barbara Sense of Direction Scale (SBSOD). READ MORE

  5. 5. Outlier detection with ensembled LSTM auto-encoders on PCA transformed financial data
