  3. 2. Development of Flourescence-based Immunosensors for Continous Carbohydrate Monotoring : Applications for Maltose and Glucose

    Författare :Henrik Engström; Sten Ohlson; Per Ola Andersson; Christopher Lowe; Högskolan i Kalmar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carbohydrate; Diabetes; Immunosensor; ; Glucose; Maltose; Weak affinity chromatograhpy; Kolhydrater; Glukos; Maltose; Affinitetskromatografi; Diabetes; Biochemistry; Biokemi; Bioteknik; Biotechnology;

    Sammanfattning : Weak affinity interaction of monoclonal antibodies and carbohydrate antigens can be detected and quantified by alterations in the antibodies' intrinsic tryptophan fluorescence. These weak/transient binding events have been monitored by total internal reflection fluorescence (TlRF) by facilitating the change in intrinsic tryptophan fluorescence. LÄS MER

  4. 3. Perturbed Markov Chains with Damping Component and Information Networks

    Författare :Benard Abola; Sergei Silvestrov; Christopher Engström; Dmitrii Silvestrov; Anatoliy Malyarenko; Milica Rancic; Vladimir Anisimov; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : This thesis brings together three thematic topics, PageRank of evolving tree graphs, stopping criteria for ranks and perturbed Markov chains with damping component. The commonality in these topics is their focus on ranking problems in information networks. LÄS MER

  5. 4. Asymptotics of implied volatility in the Gatheral double stochastic volatility model

    Författare :Mohammed Albuhayri; Anatoliy Malyarenko; Sergei Silvestrov; Ying Ni; Christopher Engström; Yulia Mishura; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : We consider a market model of financial engineering with three factors represented by three correlated Brownian motions. The volatility of the risky asset in this model is the sum of two stochastic volatilities. The dynamic of each volatility is governed by a mean-reverting process. LÄS MER

  7. 5. A Cubature Method for Solving Stochastic Equations : A Modern Monte-Carlo Approach with Applications to Financial Market

    Författare :Hossein Nohrouzian; Anatoliy Malyarenko; Ying Ni; Christopher Engström; Viktor Abramov; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : Before the financial crisis started in 2007, there were no significant spreads between the forward rate curves constructed either using the market quotes of overnight indexed swaps or those of forward rate agreements. After the crisis, we observe such spreads in the form of forward spread curves. LÄS MER
