The phenomena discussed include: quasiclassical memory effects in systems with various types of disorder, transport in lateral superlattices, interaction-induced quantum magnetoresistance, quantum magnetooscillations in dc and ac transport, and oscillatory microwave photoconductivity.Mini-review for Proceedings of the DFG Priority Progamme "Quantum Hall Systems"; to be published in a special issue of Physica Status Solidi (b); 27 pages, 22 figuresDisordered Systems and Neural NetworksMesoscale and Nanoscale Physicstext
