  3. 12. Semi Markov chain Monte Carlo

    Författare :Håkan Ljung; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Adaptive simulation; error-in-the-variables; Kullback-Leibler divergence; Markov chain simulation; Markov chain Monte Carlo; semi-regenerative; MATEMATIK; MATHEMATICS; MATEMATIK; matematisk statistik; Mathematical Statistics;

    Sammanfattning : The first paper introduces a new simulation technique, called semi Markov chain Monte Carlo, suitable for estimating the expectation of a fixed function over a distribution π, Eπf(χ). Given a Markov chain with stationary distribution p, for example a Markov chain corresponding to a Markov chain Monte Carlo algorithm, an embedded Markov renewal process is used to divide the trajectory into different parts.

  4. 13. Engraftment and tolerance induction in cellular therapy : focus on mesenchymal stromal cells

    Författare :Karin Ljung; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Different cell types have been employed in the search for a cellular therapy that is applicable for the treatment of heart failure. Remuscularization strategies using stem-cell-derived cardiomyocytes have been prone to arrhythmias. LÄS MER

  5. 14. Holocene climate and environmental dynamics on the Tristan da Cunha island group, South Atlantic

    Författare :Karl Ljung; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palynologi; Geology; climate change; pollen analysis; Palaeobotany; phylogeny; palynology; Paleobotanik; fylogeni; vegetation change; gyttja; peat; Holocene; Quaternary; South Atlantic; Tristan da Cunha; physical geography; Geologi; fysisk geografi;

    Sammanfattning : It has been shown that the present interglacial has been climatically dynamic with both rapid and severe climatic fluctuations. The spatial and temporal differences of these changes are however not fully resolved. The aim of this thesis is to present a detail high resolution record of past climate changes from the central South Atlantic. LÄS MER

  7. 15. Early diagnosis and risk stratification in patients with symptoms suggestive of acute coronary syndrome

    Författare :Lina Ljung; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Chest pain is one of the most common symptoms in patients presenting to the emergency department (ED). Identifying the minority of patients with an acute coronary syndrome (ACS) is a challenge. The introduction of high-sensitivity cardiac troponin (hs-cTn T and I) assays has radically improved the assessment. LÄS MER
