2. 1. Suspensions of finite-size rigid particles in laminar and turbulent flows

   Author : Walter Fornari; Luca Brandt; Jérémie Bec; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Suspensions; complex fluids; sedimentation; rheology; turbulence;

   Abstract : Dispersed multiphase flows occur in many biological, engineering and geophysical applications. Understanding the behavior of suspensions is a difficult task. In the present work, we numerically study the behavior of suspensions of finite-size rigid particles in different flows. READ MORE

4. 2. Immune interactions with the liver

   Author : Azza Karrar; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Liver sinusoid; endothelial cells; apoptosis; antibodies; liver immunity; biliary cells; autoimmune liver diseases; estrogen;

   Abstract : The liver has an important role in the induction of immune tolerance and can be a target for immune mediated damage. The following studies are performed to address the role of liver sinusoidal endothelial cells (LSEC) in tolerance induction and to understand some of the mechanisms involved in the pathogenesis of primary sclerosing cholangitis (PSC).

5. 3. Coding and Transmission Strategies for Secrecy

   Author : Mattias Andersson; Mikael Skoglund; Matthieu Bloch; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : In this thesis we consider several problems relating to information theoretic security. The wiretap channel is the simplest information theoretic setting which takes security into account, and in the first chapters of the thesis we design some practical coding schemes for this channel model.

6. 4. Coding for the Wiretap Channel

   Author : Mattias Andersson; Mikael Skoglund; Michael Lentmaier; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Abstract : We consider code design for Wyner’s wiretap channel. Optimal coding schemes for this channel require an overall code that is capacity achieving for the main channel, partitioned into smaller subcodes, all of which are capacity achieving for the wiretapper’s channel. READ MORE

7. 5. Mechanisms of liver allograft rejections

   Author : Xupeng Ge; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Liver transplantation; acute rejection; antibody; biliary epithelial cell; sinusoidal endothelial cell; cholangitis; toll-like receptor;

   Abstract : Liver transplantation (M) has become a standard treatment for many end-stage liver diseases. However, acute rejections still occur in about half of the liver transplant recipients even treated with a combination of different modem immunosuppressants. READ MORE
