  2. 1. System Design for Opportunistic Networks

    Author : Sylvia T. Kouyoumdjieva; Gunnar Karlsson; Andrea Passarella; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; opportunistic communication; system design; mobility; energy-saving mechanisms; device-to-device communication; mobile data offloading; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Device-to-device communication has been suggested as a complement to traditional cellular networks as a means of offloading cellular traffic. In this thesis we explore a solution for device-to-device communication based on opportunistic content distribution in a content-centric network. READ MORE

  4. 2. Cluster investigations of the extent and altitude distribution of the auroral density cavity

    Author : Love Alm; Göran T. Marklund; Tomas Karlsson; Rickard Lundin; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Auroral density cavity; auroral accelaration; Cluster; in situ observation; electron density; pseudo altitude; Physics; Fysik;

    Abstract : The auroral density cavity constitutes the boundary between the cold, dense ionospheric plasma and the hot, tenuous plasma sheet plasma. The auroral density cavity is characterized by low electron density and particle populations modified by parallel electric fields. READ MORE

  5. 3. Effects of warming and browning on benthic and pelagic ecosystem components in shallow lakes

    Author : Francisco Rivera Vasconcelos; Sebastian Diehl; Jan Karlsson; Christopher T. Solomon; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; benthic; pelagic; algae; consumers; browning; warming; shallow lakes; food web; dissolved organic matter;

    Abstract : The majority of lakes on Earth are shallow, unproductive and located at high latitudes. These lakes are experiencing big changes due to climate change, where two environmental drivers operate simultaneously, browning and warming. How they affect lake ecosystems is not well understood.

  6. 4. CD19-targeting CAR T Cells for Treatment of B Cell Malignancies : From Bench to Bedside

    Author : Hannah Karlsson; Angelica Loskog; Karl-Johan Malmberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chimeric antigen receptors; CAR T cells; T cell therapy; immunotherapy; CD19; Bcl-2 family inhibitors; B cell malignancies; Klinisk immunologi; Clinical Immunology;

    Abstract : Immunotherapy for cancer is a young research field progressing at high speed. The first chimera of an antibody and a signaling chain was designed by Zelig Eshhar and was later further developed to enhance existing T cell therapy by combining a single-chain fragment of an antibody with the CD3 zeta chain of the TCR complex.

  7. 5. T lymphocytes in allergic rhinitis

    Author : Mats G. Karlsson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The role of the T lymphocyte and T cell associated events in the allergic reaction were investigated in the nasal mucosa and in the peripheral blood. Patients with seasonal allergic rhinitis (birch pollen) and healthy controls were subjected to an allergen provocation study during non-pollen season. READ MORE
