  2. 1. A class of infinite dimensional stochastic processes with unbounded diffusion

    Author : John Karlsson; Jörg-Uwe Löbus; Christian Bayer; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malliavin calculus; Dirichlet form on Wiener space; unbounded diffusion;

    Abstract : The aim of this work is to provide an introduction into the theory of infinite dimensional stochastic processes. The thesis contains the paper A class of infinite dimensional stochastic processes with unbounded diffusion written at Linköping University during 2012. READ MORE

  4. 2. A class of infinite dimensional stochastic processes with unbounded diffusion and its associated Dirichlet forms

    Author : John Karlsson; Jörg-Uwe Löbus; Torkel Erhardsson; Hans-Jürgen Engelbert; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis consists of two papers which focuses on a particular diffusion type Dirichlet form  where  Here  is the basis in the Cameron-Martin space, H, consisting of the Schauder functions, and ν denotes the Wiener measure.In Paper I, we let  vary over the space of wiener trajectories in a way that the diffusion operator A is almost everywhere an unbounded operator on the Cameron–Martin space.

  5. 3. Improved diagnosis and management of sepsis and bloodstream infection

    Author : John Karlsson Valik; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Sepsis is a severe organ dysfunction triggered by infections, and a leading cause of hospitalization and death. Concurrent bloodstream infection (BSI) is common and around one third of sepsis patients have positive blood cultures. READ MORE

  6. 4. Protected Lignin Biorefining: Fundamental Insights on Lignin Reactivity

    Author : Maria Karlsson; Martin Lawoko; Åsa Emmer; Olena Sevastyanova; John Ralph; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sustainability; lignin; biorefinery; cyclic organosolv extraction; preserved structure; NMR; MALDI-TOF MS; Hållbarhet; lignin; bioraffinaderi; cyklisk organosolv extraktion; bevarad struktur; NMR; MALDI-TOF MS; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The potential to utilize lignin, which constitutes as much as 15-30% of the biomass, needs further evaluation. In the transition towards a bioeconomy, lignin has the potential to replace fossil-based phenols. Attempts to valorize the available technical lignins are ongoing; however, that lignin suffers from molecular heterogeneity. READ MORE

  7. 5. Communicating climate action : Combining action repertoires and linguistic repertoires in social movement message construction

    Author : Sol Agin; Michael Karlsson; Emilia Ljungberg; John Lynch; Ulrika Olausson; Karlstads universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; climate change communication; social movements; communicative action repertoire alignment; emotional appeals; threat perception; Media and Communication Studies; Medie- och kommunikationsvetenskap;

    Abstract : The climate crisis is one of the largest global challenges that humanity has ever faced. Despite the scientific consensus on the threat, action is not occurring on the pace or level needed to stave off the consequences. READ MORE
