  1. 1. Inflammation-associated genes and genetic variations in colorectal cancer

    Författare :Nils Elander; Peter Söderkvist; Karin Fransén; Mef Nilbert; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Colorectal cancer is a major cause of morbidity and mortality around the world, each year affecting about one million individuals worldwide. The disease is characterized by an accumulation of genetic alterations, and a sequence of events leading to the development of an invasive and metastasising tumour. LÄS MER

  3. 3. A Theoretical Study of Atomic Trimers in the Critical Stability Region

    Författare :Moses Salci; Nils Elander; Sergey Levin; Gunnar Nyman; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; atomic trimers; halos; quantum resonances; finite element method; Physics; Fysik;

    Sammanfattning : When studying the structure formation and fragmentation of complex atomic and nuclear systems it is preferable to start with simple systems where all details can be explored. Some of the knowledge gained from studies of atomic dimers can be generalised to more complex systems. LÄS MER

  4. 4. Ways of determining and characterising resonances in scattering processes

    Författare :Ksenia Shilyaeva; Nils Elander; Dage Sundholm; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; quantum scattering theory; complex scaling; resonances; Molecular physics; Molekylfysik; Physics; fysik;

    Sammanfattning : Scattering cross sections very often display structures. To clarify if these structures correspond to resonances one has to check if they are poles of the scattering matrix (S-matrix) in the fourth quadrant of the complex momentum plane. Furthermore, the states corresponding to these poles also need to have an appropriate scattering amplitude. LÄS MER

  5. 5. Solving the quantum scattering problem for systems of two and three charged particles

    Författare :Mikhail Volkov; Nils Elander; William McCurdy; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Scattering theory; three body scattering; Atomic and molecular physics; Atom- och molekylfysik; Mathematical physics; Matematisk fysik; Physics; fysik;

    Sammanfattning : A rigorous formalism for solving the Coulomb scattering problem is presented in this thesis. The approach is based on splitting the interaction potential into a finite-range part and a long-range tail part. In this representation the scattering problem can be reformulated to one which is suitable for applying exterior complex scaling. LÄS MER
