  1. 1. A Multitype Branching Processes Approach to the Evolutionary Dynamics of Escape

    Författare :Maria Conceicao Serra; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galton-Watson branching processes; multitype; decomposable processes; population dynamics; extinction; mutation; path to escape; waiting time to escape; Galton-Watson branching processes;

    Sammanfattning : Evolutionary dynamics of escape is a recent development in theoretical biology. It is an attempt to predict possible patterns of population dynamics for a certain strain of viruses placed in a hostile environment. The only way to escape extinction for the virus is to find a new form better adapted to the new environment. LÄS MER

  3. 2. The Final Size of Multitype Chain-Binomial Epidemic Processes

    Författare :Mikael Andersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multitype epidemic process; counting process; Markov process; weak convergence; counting process;

    Sammanfattning : A multitype chain-binomial epidemic process is defined for a closed finite population by sampling a simple multidimensional counting process at certain points. The final size of the epidemic is then characterised, given the counting process, as the smallest root of a non-linear system of equations. LÄS MER

  5. 4. Towards Precision Medicine: Exploiting Genetic Variation in Tumours by Inferring Multitype Gene Regulatory Networks

    Författare :Tobias Abenius; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; precision medicine; survival; cancer; gene regulatory networks; high-dimensional data; LASSO; Reproducible research; Generalized Pairwise Fused LASSO; Split Bregman;

    Sammanfattning : Precision medicine aims to customize treatment to a patient given measured genetic or other molecular data for diagnostics. In cancer, optimal medical treatment, depends on how far the disease has progressed, type and subtype of cancer and, the individual tumor’s circumstances. LÄS MER

  7. 5. Extensions of the Reed-Frost process

    Författare :Gianpaolo Scalia-Tomba; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The Reed-Frost process is a discrete time stochastic model for the spread of an infectious disease in a homogeneous population. In this work, extensions of the basic model are investigated. LÄS MER
