  2. 1. The space of Cohen–Macaulay curves and related topics

    Author : Katharina Heinrich; Roy Skjelnes; Ragni Piene; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : The space of Cohen–Macaulay curves is a compactification of the space of curves that are embedded in a given projective space Pn. The idea is similar to that of the Hilbert scheme but instead of adding degenerated curves, one considers only curves without embedded or isolated points. READ MORE

  4. 2. Human cytotoxic lymphocyte differentiation in health and disease

    Author : Heinrich Schlums; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cytotoxic lymphocytes, comprising natural killer (NK) cells and CD8+ cytotoxic T cells, eradicate infected or malignant cells by release of lytic granules and alarm the immune system through production of pro-inflammatory cytokines and chemokines. NK cells and CD8+ T cells belong to different arms of the immune system, employing complementary strategies for target cell recognition. READ MORE

  5. 3. Drivers of Population Dynamics in Bacterioplankton : Spotlight on Alphaproteobacteria and its dominant SAR11 Lineage

    Author : Friederike Heinrich; Stefan Bertilsson; Alexander Eiler; David Kirchman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacterial community dynamics; Alphaproteobacteria; SAR11; LD12; Southern Ocean; lakes; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Bacteria are mediators of biogeochemical cycles and are in this way vital for maintaining life on earth. Their distribution, abundance and functioning are driven by environmental heterogeneity and dynamic change in abiotic and biotic factors. READ MORE

  6. 4. Coping with Stress : Regulation of the Caulobacter crescentus cell cycle in response to environmental cues

    Author : Kristina Heinrich; Kristina Jonas; Emanuele Biondi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Caulobacter crescentus; bacteria; cell cycle; stress; filamentation; cell morphology; DNA replication; cell division; molekylär biovetenskap; Molecular Bioscience;

    Abstract : All organisms have to respond to environmental changes to maintain cellular and genome integrity. In particular, unicellular organisms like bacteria must be able to analyze their surroundings and rapidly adjust their growth mode and cell cycle program in response to environmental changes, such as changes in nutrient availability, temperature, osmolarity, or pH.

  7. 5. The space of Cohen-Macaulay curves

    Author : Katharina Heinrich; Roy Skjelnes; Lars Halvard Halle; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis we discuss a moduli space of projective curves with a map to a given projective space. The functor CM parametrizes curves, that is, Cohen-Macaulay schemes of pure dimension 1, together with a finite map to the projective space that is an isomorphism onto its image away from a finite set of closed points.
