We present coding methods for protecting against tampering of write-once optical disks which turns them into a secure digital medium for applications where critical information must be stored in a way that prevents or allows detection of an attempt at falsiication. Our method involves adding a small amount of redundancy to a modulated sector of data. This extra redundancy is not used for normal...

The rapid prosperity and future prospects of this colony are to me, not understanding these subjects, very puzzling. The two main exports are wool and whale oil, and to both of these productions there is a limit. Pasture everywhere is so thin that settlers have already pushed far into the interior: moreover the country further inland becomes extremely poor. Agriculture, on account of the drough...

It is shown that there is a distinctively practical sort of know-how and a corresponding interpretation of 'S knows how to 0', and that this special sort of know-how, while possessing representational content, is not simply ordinary knowledge-that. The view rests on a novel distinction be...

Serum erythropoietin (EPO) concentration was measured by an enzyme-linked immunosorbent assay (ELISA) in 31 cases of chronic renal failure (CRF), including 20 hemodialysis (HD) patients, and compared with that of 31 healthy normal controls. Each patient served as a self-control comparing his or her pretreatment level with post-treatment values. There was a significant negative correlation ...
