This paper is concerned with the differences between deterministic and randomized finite-memory decision rules. It is shown that for any hypothesis-testing problem there exists a b < CO such that, for any B, the optimal deterministic rule with B + b bits in memory has a lower error probability than the optimal randomized rule with B bits in memory. Suboptimal deterministic rules with this prope...

background and objectives : carbapenem resistant pseudomonas aeruginosa is a serious cause of nosocomial infections.the main purpose of the study is to determine the prevalence rate of imipenem resistant pseudomonas aeruginosa carrying metallo- beta- lactamase (mbl) genes. material and methods : 236 pseudomonas aeruginosa isolates were collected from teaching hospitals of ahvaz university of me...

background klebsiella pneumoniae is a family member of enterobacteriaceae. isolates of k. pneumoniae produce enzymes that cause decomposition of third generation cephalosporins. these enzymes are known as extended-spectrum beta-lactamase (esbl). resistance of k. pneumoniae to beta-lactamase antibiotics is commonly mediated by beta-lactamase genes. objectives the aim of this study was to identif...

ation of many strings. Rule-based systems can do better , but the rules are based on years of s tudy by phoneticians, and are not only complex, but are supplemented by large lists of lexical exceptions. Presumably a connectionist system that could be taught rules as well as learn from example would outperform both versions; and that is what a human seems to b e a system that can be taught rules...

in this paper,  we determine necessary and sufficient tauberian conditions under which convergence in pringsheim&apos;s sense of a double sequence of fuzzy numbers follows from its $(c,1,1)$ summability. these conditions are satisfied if the double sequence of fuzzy numbers is slowly oscillating in different senses. we also construct some interesting double sequences of fuzzy numbers.

Cultured cells cloned from the C1300 neuroblastoma have been shown by several laboratories to extend neurites (1-6) and to accumulate nervespecific enzymatic activities (7) when grown under conditions in which cell division is inhibited. Study of this system has been stimulated by the hope that it might serve as an in vitro model of nerve cell differentiation. Many of the neurite-inducing agent...

the glucose oxidase (gox) electrochemical sensors were used to detect a little amount of glucose. in this paper, the pure platinum plate (length of 5 cm and a width of 3 mm), the ag/agcl electrode and platinum electrode (diameter of 1 mm) were applied as a working electrode (w.e), reference electrode and auxiliary electrode sequential. factors measured, glucose concentration and ph is phosphate...
