  1. 1. On Face Vectors and Resolutions

    Författare :Afshin Goodarzi; Anders Björner; Volkmar Welker; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis consist of the following three papers.Convex hull of face vectors of colored complexes. In this paper we verify a conjecture by Kozlov (Discrete ComputGeom18(1997) 421–431), which describes the convex hull of theset of face vectors ofr-colorable complexes onnvertices. LÄS MER

  2. 2. Topological and Shifting Theoretic Methods in Combinatorics and Algebra

    Författare :Afshin Goodarzi; Anders Björner; Volkmar Welker; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Mathematics; Matematik;

    Sammanfattning : This thesis consists of six papers related to combinatorics and commutative algebra.In Paper A, we use tools from topological combinatorics to describe the minimal free resolution of ideals with a so called regular linear quotient. Our result generalises the pervious results by Mermin and by Novik, Postnikov & Sturmfels. LÄS MER

  3. 3. Advances in Task-Based Parallel Programming for Distributed Memory Architectures

    Författare :Afshin Zafari; Elisabeth Larsson; George Bosilca; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel programming; task-based programming; distributed memory system; scientific computing; hierarchical data; hierarchical tasks;

    Sammanfattning : It has become common knowledge that parallel programming is needed for scientific applications, particularly for running large scale simulations. Different programming models are introduced for simplifying parallel programming, while enabling an application to use the full computational capacity of the hardware. LÄS MER

  4. 4. Approaches for analysis of mutations and genetic variations

    Författare :Afshin Ahmadian; KTH; []
    Nyckelord :LOH; microsatellite; fragment analysis; DNA sequencing; pyrosequencing; cancer; mutation; variation; SNP; allele-specific extension; apyrase; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Detecting mutations and genomic variations is fundamental indiagnosis, isolating disease genes, association studies,functional genomics and pharmacogenomics. The objective hasbeen to use and further develop a variety of tools andtechnologies to analyze these genetic alterations andvariations. LÄS MER

  5. 5. Influence of oxidative stress on aryl hydrocarbon receptor signaling

    Författare :Afshin Mohammadi Bardbori; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : The aryl hydrocarbon receptor (AHR), a multifunctional protein and a key regulator of drug metabolizing enzymes, belongs to the basic-helix-loop-helix (bHLH)/PAS (Per- Arnt-Sim) super-family of transcription factors. The AHR responds to exogenous and endogenous chemicals by induction or repression of a large number of genes involved in many physiological processes and normal development. LÄS MER
