متن کاملAccuracy evaluation of NIST-F1
The evaluation procedure of a new laser-cooled caesium fountain primary frequency standard developed at the National Institute of Standards and Technology (NIST) is described. The new standard, NIST-F1, is described in some detail and typical operational parameters are discussed. Systematic frequency biases for which corrections are made – second-order Zeeman shift, black-body radiation shift, ...
متن کاملHistone F1 of Tetrahymena Macronuclei
Histone fraction F1 has been isolated and purified from macronuclei of the ciliated protozoan, Tetrahymena pyriformis. In many respects, Tetrahymena F1 is similar to that of other organisms. It is the only Tetrahymena histone soluble in 5% perchloric acid or 5% trichloroacetic acid, has a higher molecular weight than any other Tetrahymena histone, is the histone most easily dissociated from Tet...
متن کاملF1-schemes and Toric Varieties
There are by now several attempts to make the theory of the field of one element F1 rigorous. In [10] the authors formalize the transition from rings to schemes on a categorial level and apply this machinery to the category of sets to obtain the category of F1-schemes as in [1]. In [3] and [5] the authors extend the definition of rings in order to capture a structure that deserves to be called ...
متن کاملSelective response to H-Y antigen by F1 female mice sensitized to F1 male cells
T-cell mediated cytotoxic responses to H-Y antigen require co-recognition of H-Y and H-2 gene products. F1 mael stimulating cells and target cells express H-Y antigen in association with both parental H-2 haplotypes. However, F1 females primed in vivo and challenged in vitro with F1 male cells lyse male target cells of F1 and only one parental H-2 haplotype. Thus, (CBA X B10)F1 females sensitiz...
