We report on an ASCA discovery of a new X-ray pulsar, AX J0049−732, in the Small Magellanic Cloud (SMC). The pulse shape is sinusoidal with a barycentric period of 9.1320 ± 0.0004 s. The X-ray spectrum was fitted by an absorbed power-law model with a photon index of 0.6 −0.7 and a column density of 1.3 −1.3 × 10 22 cm. An unabsorbed flux at 0.7–10.0 keV was estimated to be 8× 10 erg cm s corres...

There is investigated generalized Tychonov well-posedness of the problem of minimization of error functionals over admissible sets formed by variable-basis functions, which include neural networks. For admissible sets formed by variable-basis functions of increasing complexity, rates of decrease of infima of error functionals are estimated. There are derived upper bounds on such rates that do n...

Degradable polymers based on polyanhydrides are essentially polymeric prodrugs; the polymers hydrolytically degrade into salicylic acid, just as aspirin hydrolyzes into salicylic acid upon ingestion. This talk describes medical applications where the polymer serves as a temporary barrier that degrades into therapeutically active molecules such as non-steroidal antiinflammatory drugs (NSAIDs) an...
