  1. 1. On Probabilistic Shaping and Learned Decoders with Application to Fiber-Optic Communications

    Författare :Andreas Buchberger; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Error correcting codes; learned decoders; machine learning; iterative decoding; probabilistic shaping; fiber-optic communications; pruning;

    Sammanfattning : We live in an ubiquitously connected world whose backbone are optical fibers. Achieving high spectral efficiencies and hence high transmission rates requires a careful combination of forward error correction (FEC) and higher-order modulation. This is referred to as coded modulation. LÄS MER

  4. 3. Computational Approaches to the Degeneration of Brain Networks and Other Complex Networks

    Författare :Simachew Abebe Mengiste; Jeanette Hällgren Kotaleski; Arvind Kumar; Ad Aertsen; Michelle Rudolph; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neurodegeneration; Synaptic pruning; Networks; Structure; Dynamics; Controllability;

    Sammanfattning : Networks are ubiquitous with several levels of complexity, configuration, hierarchy and function. Many micro- and macro-scale biological or non-biological interactions define complex systems. LÄS MER

  5. 4. On macrophage contributions to tissue homeostasis : New insights on pancreas development and healing of ischemic injury

    Författare :Carmen Herrera Hidalgo; Mia Phillipson; Andrés Hidalgo; Uppsala universitet; []
    Nyckelord :macrophages; islets of Langerhans; β cell function; postnatal β cell maturation; hindlimb ischemia; blood flow regulation; mural cells; vessel pruning; diabetes mellitus; ischemic diseases;

    Sammanfattning : Besides providing host defence against innumerable threats, macrophages display additional key functions for preservation of tissue homeostasis. This thesis includes four studies that explore novel macrophage functions in both the development of islets of Langerhans and healing of ischemic injury in mice. LÄS MER
