  1. 41. Using Trees to Capture Reticulate Evolution : Lateral Gene Transfers and Cancer Progression

    Författare :Ali Tofigh; Jens Lagergren; Mike Steel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lateral Gene Tranfer; Horizontal Gene Transfer; Cancer Progression; Bioinformatics; Bioinformatik; Computer science; Datalogi;

    Sammanfattning : The historic relationship of species and genes are traditionally depicted using trees. However, not all evolutionary histories are adequately captured by bifurcating processes and an increasing amount of research is devoted towards using networks or network-like structures to capture evolutionary history.

  2. 42. Inter and intra-tumor models of somatic evolution in cancer

    Författare :Mohammadreza Mohaghegh Neyshabouri; Jens Lagergren; Ben Raphael; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cancer progression models; MCMC; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Sammanfattning : Cancer is a disease caused by the accumulation of somatic mutations in an evolutionary process. Mutations in so-called cancer driver genes provide the harboring cells with particular selective advantages and result in cancer progression. LÄS MER

  3. 43. Intelligence-Driven Software Performance Assurance

    Författare :Mahshid Helali Moghadam; Markus Bohlin; Mehrdad Saadatmand; Markus Borg; Björn Lisper; Antonia Bertolino; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : Software performance assurance is of great importance for the success of software products, which are nowadays involved in many parts of our life. Performance evaluation approaches such as performance modeling, testing, as well as runtime performance control methods, all can contribute to the realization of software performance assurance.

  4. 44. Computational Problems in Modeling Evolution and Inferring Gene Families

    Författare :Mehmood Alam Khan; Lars Arvestad; Jens Lagergren; Christophe Dessimoz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution; Phylogenetics; Lateral Gene Transfer; Gene Families; Clustering; Datalogi; Computer Science;

    Sammanfattning : Over the last few decades, phylogenetics has emerged as a very promising field, facilitating a comparative framework to explain the genetic relationships among all the living organisms on earth. These genetic relationships are typically represented by a bifurcating phylogenetic tree — the tree of life. LÄS MER

  5. 45. Enhancing Differential Evolution Algorithm for Solving Continuous Optimization Problems

    Författare :Miguel Leon; Ning Xiong; Yigen Zenlander; Peter Funk; Ronnie Johansson; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : Differential Evolution (DE) has become one of the most important metaheuristics during the recent years, obtaining attractive results in solving many engineering optimization problems. However, the performance of DE is not always strong when seeking optimal solutions. It has two major problems in real world applications. LÄS MER
