Popular Abstract in Swedish I kroppen produceras varje dag ca 1 000 000 000 000 nya blodceller för att ersätta celler som förbrukats eller sorterats undan som odugliga. I toppen av hierarkin finns den hematopoietiska stamcellen, eller blodstamcellen, en cell med ett antal unika egenskaper: (i) Förmågan att dela sig och ge upphov till minst en ny blodstamcell (cell med samma egenskaper som modercelHOXB4 is one of 39 members of the homeobox (HOX) family, a family of transcription factors involved in embryonic development. Several HOX transcription factors, including HOXB4, are highly expressed in hematopoietic stem cells (HSCs) but are downregulated upon differentiation towards more mature progeny cells. Enforced expression of HOXB4 dramatically increases the regeneration of murine HSC follo

In this paper we examine the ambiguities between extrinsic and intrinsic parameters in the uncalibrated structure and motion problem. The Jacobian J of the reprojection error is considered, treating each camera separately. Ambiguities correspond to linear dependencies in the column space of J and we thus detect and quantify these by using the condition number of selected combinations of columns of

This paper reconsiders how central banks get involved in the process of determining nominal variables such as market interest rates and inflation rates. It is argued that the traditional story deriving central bank power from its monopoly of issuing base money is flawed. That story - in its various guises - is based on the quantity equation. This equation, however, is only applicable in the hypoth

Language use is fundamentally multimodal. Speakers use their hands to point to locations, to represent content and to comment on ongoing talk; they position their bodies to show their orientation and stance in interaction; they use facial displays to comment on what is being said; and they engage in mutual gaze to establish intersubjectivity. This volume brings together studies by leading scholars

De nordiska länderna har i stort sett likalydande avtalslagar. Den svenska avtalslagen har i år varit i kraft i 100 år och avtalslagarna i de övriga nordiska länderna är nästan lika gamla.I denna bok bidrar ett antal nordiska rättsvetenskapliga forskare med analyser av avtalslagarnas bakgrund, deras nuvarande betydelse i den moderna nordiska avtalsrätten liksom frågan om hur väl de kan förväntas f
