A plasma membrane fraction of HeLa Sa cells, consisting of ghosts, is characterized more fully. A simple procedure is described which permits light and electron microscope study of the plasma membrane fraction through the entire depth of the final product pellet and through large areas parallel to the surface. Contamination by nuclei is 0.14%, too little for DNA detection by the diphenylamine r...

THE N - EXTENT OF S 3 ( p , m ) PAUL

In this paper we estimate xtn S3 (p, m) , the n-extent of various lens spaces. We give numerical evidence for extending certain results of D. G. Yang [Duke Math. J., 74 (1994), 531-545.] to primes p between 11 and 37. We explain the implication of our results for the topology of 4-dimensional manifolds of positive sectional curvature with nontrivial isometric Zp-actions.

M - Theory Solutions in Multiple Signatures from E 11 Paul

We generalise the previously given E11 half BPS solution generating group element to general weights of A10. We find that it leads to solutions of M The signature transformations of the solution are naturally generated by the Weyl reflections required to transform the lowest A10 weight into a general weight in the same representation. We also rediscover known S-brane solutions in M-theory from ...

In this paper, we present a theory of synchronous data-ow languages. Our theory is supported by both some heuristic analysis of applications and some theoretical investigation of the data-ow paradigm. Our model covers both behavioural and operational aspects, and allows both synchronous and asynchronous styles of implementation for synchronous programs. This model served as a basis to establish...
