  1. 1. Studies of Light Emitting Devices Based on Er-doped Si and SiGe Layered Structures

    Author : Chun-Xia Du; Fransesco Priolo; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electroluminescence; diode; transistor; hot electron; recombination; excitation; de-excitation; Auger effect; molecular beam epitaxy; Er; Si; SiGe;

    Abstract : Doping with rare earth element erbium (Er) in Si has recently attracted a lot of research interest due to potential applications in Si-based opto-electronics. By using molecular beam epitaxy (MBE), precipitate-free Er-doping in Si has been made together with other co-dopants, e.g., oxygen (0) and fluorine (F), up to a level ∼1020 cm-3. READ MORE

  2. 2. Upconversion in Er doped silica : - characterization and modeling

    Author : Dmitry Khoptyar; Bozena Jaskorszynska; Anders Bjarklev; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Further increase of erbium concentrations in Er-doped amplifiers and lasers is needed for the design of efficient, reliable, compact and cost-effective components for telecommunications and other photonic applications. However, this is hindered by Er concentration dependent loss mechanism known as upconversion. READ MORE

  3. 3. Predictive markers for tamoxifen response in primary breast cancer

    Author : Maria Stendahl; Malmö Patologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; General pathology; Cytologi; onkologi; prognosis; Cytology; oncology; cancerology; predictive marker; p27; cyclin D1; tamoxifen; PR; breast cancer; ER; pathological anatomy; Patologi allmän ; patologisk anatomi;

    Abstract : It is well-known that a majority of breast cancers are hormone-dependent, making endocrine therapy an important adjuvant treatment after surgery. Susceptibility to endocrine treatment is determined by the presence of estrogen receptors (ER) and progesterone receptors (PR) in the tumors. READ MORE

  4. 4. Storage organelles that are distinct from the classical granules in human neutrophils

    Author : Sara Pellmé; Göteborgs universitet; []
    Keywords : neutrophil; HL-60 cells; cytoplasts; granules; CXCL-8; ER; phagocytosis; HLA-I; subcellular fractionation; immunogold;

    Abstract : The human neutrophil is a crucial participant in acute inflammation. Appropriate immune response is dependent on rapid direction of phagocytic cells through the tissue, towards the inflammatory focus. Such movement is governed by chemoattractants, e.g. READ MORE

  5. 5. Mobility Management and Localizability for Cellular Connected UAVs

    Author : Irshad Ahmad Meer; Cicek Cavdar; Mustafa Ozger; Ki Won Sung; Halim Yanikomeroglu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Unmanned aerial vehicles; Localization; Service availability; Air-to-ground channel; Mobility; Handover; Unmanned aerial vehicles; Localization; Service availability; Air-to-ground channel; Mobility; Handover;

    Abstract : Unmanned Aerial Vehicles (UAVs) connected to cellular networks present novel challenges and opportunities in mobility management and localization, distinct from those faced by terrestrial users. This thesis presents an integrated approach, combining two key aspects essential for the integration of UAVs with cellular networks. READ MORE
