  1. 1. Reinforcement in Biology : Stochastic models of group formation and network construction

    Författare :Qi Ma; David Sumpter; Edward Codling; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reinforcement in biology; merge and split model; preferential attachment; reinforced random walk; network construction; shortest path problem; transport networks; ant algorithm; slime mould; physarum polycephalum; speed-accuracy tradeoff.; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

    Sammanfattning : Empirical studies show that similar patterns emerge from a large number of different biological systems. For example, the group size distributions of several fish species and house sparrows all follow power law distributions with an exponential truncation. LÄS MER

  3. 2. Mathematical modelling approach to collective decision-making

    Författare :Natalia Zabzina; Denis Gaidashev; Torbjörn Lundh; Uppsala universitet; []
    Nyckelord :collective behaviour; collective decision-making; communication mechanisms; positive feedback; mathematical modelling; bifurcation phenomena; steady state solutions; symmetry breaking; symmetry restoring; diffusion-limited aggregation; fractal dimension;

    Sammanfattning : In everyday situations individuals make decisions. For example, a tourist usually chooses a crowded or recommended restaurant to have dinner. Perhaps it is an individual decision, but the observed pattern of decision-making is a collective phenomenon. LÄS MER

  4. 3. The Art of Modelling Oscillations and Feedback across Biological Scales

    Författare :Linnéa Gyllingberg; David J. T. Sumpter; Helen Byrne; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mathematical biology; mathematical modelling; oscillations; feedback mechanisms; dynamical systems; individual-based models; complex systems; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

    Sammanfattning : This thesis consists of four papers in the field of mathematical biology. All papers aim to advance our understanding of biological systems through the development and application of innovative mathematical models. LÄS MER
