  1. 6. Streptococcal protein Rib and related proteins: a family of repetitive surface proteins that elicit protective immunity

    Författare :Margaretha Stålhammar-Carlemalm; Institutionen för laboratoriemedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; cross-protection; epithelial cell adhesion; protective immunity; vaccination; surface proteins; Group B streptococcus; Streptococcus pyogenes; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : ABSTRACT Streptococci constitute a heterogeneous group of Gram-positive bacteria, divided into different serological groups on the basis of antigenic differences in a cell wall-associated carbohydrate. This thesis describes related surface proteins expressed by bacteria in two of these groups, the group B streptococcus (GBS) and the group A streptococcus (GAS). LÄS MER

  3. 7. Precision in neuropsychology. Four challenges when using simplified assumptions

    Författare :Jacob Stålhammar; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuropsychology; practice effects; mild cognitive impairment; dementia; second language effects; bilingualism;

    Sammanfattning : Cognition comprises all thought processes, from perception to memory. Neuropsychological tests are the gold standard (= best way) to measure cognition. However, clinical assessment may at times have to rely on simplified assumptions. LÄS MER

  4. 8. Knots and Transport in Topological Matter

    Författare :Marcus Stålhammar; Emil Johansson Bergholtz; Christiane Morais Smith; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transport; Knots; Topology; non-Hermiticity; Weyl semimetals; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Topology has manifestations in physics ranging from the field of condensed matter to photonics. This dissertation provides a two-fold study on the impact of topology in Hermitian and non-Hermitian band structures. LÄS MER

  5. 9. Knotted Nodal Band Structures

    Författare :Marcus Stålhammar; Emil Bergholtz; Edwin Langmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Sammanfattning : It is well known that in conventional three dimensional (3D) Hermitian two band models, the intersections between the energy bands are generically given by points. The typical example are Weyl semimetals, where these singular points can be effectively described as Weyl fermions in the low energy regime. LÄS MER
