    Sammanfattning : Mechanical forces exists in many cellular processes, including cell proliferation, migration, rearrangement and differentiation. The transformation of cancer cells from normal cells, cancer metastasis and cell rearrangement during morphogenesis all involve changes in cellular mechanical forces. LÄS MER

  2. 2. Sequence and dispersion of repolarization of the right atrium: Implications of repolarization disturbance in atrial fibrillation

    Författare :Zhen Li; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; electroanatomical mapping; monophasic action potential; atrial fibrillation; repolarization; dispersion;

    Sammanfattning : To explore the global sequence and dispersion of repolarization of the right atrium, monophasic action potentials (MAPs) were sequentially recorded from the right atrium using an electroanatomical mapping (CARTO) system in 10 healthy pigs and in 10 patients with (n=6) and without (n=4) paroxysmal atrial fibrillation (PAF) during sinus rhythm, or using two MAP recording catheters in 30 patients with or without PAF (n=15 each) during sinus rhythm, pacing, and programmed stimulation. The dispersion of activation time (AT), repolarization time (RT) and MAP duration (MAPd) were analyzed. LÄS MER

    Författare :Zhen Zhang; Shi-Li Zhang; Tsu-Jae King Liu; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS technology; MOSFET; FinFET; Schottky diode; Schottky barrier soure drain; silicide; SALICIDE; SOI; multiple-gate; nanowire; sidewall transfer lithography; Electronics; Elektronik;

    Sammanfattning : The steady and aggressive downscaling of the physical dimensions of the conventional metal-oxide-semiconductor field-effect-transistor (MOSFET) has been the main driving force for the IC industry and information technology over the past decades. As the device dimensions approach the fundamental limits, novel double/trigate device architecture such as FinFET is needed to guarantee the ultimate downscaling. LÄS MER

  4. 4. Silicon Nanowire Field-Effect Devices as Low-Noise Sensors

    Författare :Xi Chen; Zhen Zhang; Shi-Li Zhang; Si Chen; Fengnian Xia; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon nanowire; field-effect transistor; Schottky junction gate; low frequency noise; ion sensor; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : In the past decades, silicon nanowire field-effect transistors (SiNWFETs) have been explored for label-free, highly sensitive, and real-time detections of chemical and biological species. The SiNWFETs are anticipated for sensing analyte at ultralow concentrations, even at single-molecule level, owing to their significantly improved charge sensitivity over large-area FETs. LÄS MER
