Factoring is believed to be a diflcult task. Although factoring is of interest in its own right, the security of RSA cryptography, among other cryptographic systems, is dependent on the diflculty of factoring the product of two large primes. We show how to cast the problem of factoring integers as a state-based search to which the techniques of AI may be applied. Using small primes as operators...

Results OPN levels (ng/ml) were significantly higher in asthmatics in exacerbation period when compared to nonexacerbation period, and controls [30,61±3,21 vs. 28,7 ±3,71 vs. 27,62±3,91, respectively; p<.001]. There was no significant difference among OPN levels between asthmatics and controls, (p=.094). 25(OH)D levels (ng/ml) were significantly lower in asthmatics in exacerbation period when c...

A new categorical factor analysis metbad is proposed and it is applied to investigate the influence of phonemic context on the distribution ofvowel spectra. Conventional categorical factor analysis methods, such as quantification theory, assume that the influence ofmultiple categories are expressed by the linear combination of that of single category. In onr method, the theory is modified to de...
