Crossover from hc Õe to hc Õ2e current oscillations in rings of s-wave superconductors

We analyze the crossover from an hc /e periodicity of the persistent current in flux-threaded clean metallic rings toward an hc /2e-flux periodicity of the supercurrent upon entering the superconducting state. On the basis of a model calculation for a one-dimensional ring we identify the underlying mechanism, which balances the hc /e versus the hc /2e periodic components of the current density....

We thank Dr Schachner for his interest and comments on our recent experimental findings [1]. The first facet of our study was that although initially (at 1 month), neointima formation in vein grafts was inhibited by perivenous application of fibrin glue at the time of implantation, at 4 months neointimal formation was not significantly different from controls [1]. Dr Schachner has implied that ...

We appreciate the comments of Drs von Oppell and Rammohan on our article. The definition in our paper relates specifically to deep sternal wound infections and we appreciate that perhaps this is not made abundantly clear in the methodology. Superficial wound infections were defined as those that do not penetrate the subcutaneous tissue layer. The wound may exhibit erythema and a small amount of...
