  2. 1. Experimental and theoretical study of quantum dot resonant tunneling diodes for single photon detection

    Author : Ying Hou; Ying Fu; KTH; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Single photon detection has a broad application in the medical, telecommunication, as well as in infrared imaging fields. In this thesis I present my work in studying quantum dot (QD) resonant tunneling diodes (RTD) for single photon detection. The device was processed in the form of a free-standing small-area air bridge. READ MORE

  4. 2. Design and Evaluation of 3D Multimodal Virtual Environments for Visually Impaired People

    Author : Ying Ying Huang; Yngve Sundblad; Eva-Lotta Sallnäs; Charlotte Magnusson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multimodal interaction; 3D worlds; Haptics; Audio; Visually impaired users; Collaboration; Navigation; Computer science; Datavetenskap;

    Abstract : Spatial information presented visually is not easily accessible to visually impairedusers. Current technologies, such as screen readers, cannot intuitively conveyspatial layout or structure. This lack of overview is an obstacle for a visuallyimpaired user, both when using the computer individually and when collaboratingwith other users. READ MORE

  5. 3. Regulation of striated muscle contraction

    Author : Ying Dou; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background and Aims: Muscle contraction involves cross-bridge interaction between actin and myosin filaments, which is regulated by variations of intracellular [Ca2+] and influenced by several external control systems. To characterize the mechanism of contraction, we have studied the effects of pharmacological compounds influencing the actin-myosin interaction and/or Ca2+ activation systems. READ MORE

  6. 4. A novel principle for immunomodulator delivery with hematopoietic cells as vehicles Focus on soluble TNF-receptor gene expression, targeting to secretory lysosomes and regulated secretion

    Author : Ying Gao; Avdelningen för hematologi och transfusionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellulära vätskor; extracellular fluids; Hematologi; Medicin människa och djur ; Haematology; Medicine human and vertebrates ; neutrophil; granule; secretory lysosome; sorting; phagocytosis; degranulation.; mast cell; hematopoietic cell; inflammation; soluble TNF receptor;

    Abstract : The goal of this research is to use hematopoietic cells as vehicles for targeting transgenic immunomodulators to the inflammatory sites. The work presented was focused on the anti-inflammatory soluble TNF receptor. A transmembrane soluble TNF receptor (sTNFR1) construct was expressed in hematopoietic cell lines. READ MORE

  7. 5. Effects of eye and neck muscle proprioception on ocular motor control in normal and strabismic subjects

    Author : Ying Han; Karolinska Institutet; Karolinska Institutet; []
    Keywords : strabismus; binocular function; proprioception; eye position; muscle vibration; eye muscle; neck muscle; hand pointing; accommodative vergence movement; dynamics;

    Abstract : Abundant proprioceptive information originates in eye and neck muscles but their role in normal visual function is unknown. Under experimental conditions, proprioceptive activation induces illusory visual movement, whereas clinical evidence indicates that proprioceptive dysfunction causes disturbances in spatial orientation.
