  1. 1. Predictor Antennas : Enabling channel prediction for fast-moving vehicles in wireless broadband systems

    Författare :Joachim Björsell; Mikael Sternad; Anders Ahlén; Fredrik Tufvesson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Predictor antenna; Channel prediction; Long-range prediction; Massive MIMO; Spline interpolation; Channel aging; Outdated CSI; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Sammanfattning : Many advanced transmission techniques utilize channel state information (CSI) at the transmitter (CSIT) to improve throughput, spectral efficiency, power efficiency, and other performance metrics. Estimating CSI accurately is important to fully benefit from many of these techniques. LÄS MER

  4. 3. Regulation of insulin secretion in diabetes: Molecular mechanism and applications

    Författare :Rui Wu; Diabetes - öpatofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Insulin production secretion; CaV channels; DEGs; aging; magnetic field;

    Sammanfattning : Diabetes is a highly ageing-related disease manifesting with a deteriorated capacity of insulin secretion and uncontrolled blood glucose-raising, hyperglycemia. In this thesis, we aim to explore the underlying roles of CaV channels and aging-associated genetic changes in the development of Type 2 diabetes (T2D). LÄS MER

  5. 4. Stochasticity in Biophysical Systems: Searching, Aging, and Spreading

    Författare :Lloyd Sanders; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anomalous diffusion; Single-file; Markov process; Epidemiology; First Passage Time;

    Sammanfattning : The role of stochasticity throughout many biophysical systems is of great importance. From evolution to foraging, from the spreading of viruses to cell fate, all hinge in one way or another on inherent stochasticity. LÄS MER
