We prove that there is a family of permutations which are computable by a family ofNC circuits while their inverses are P-hard to compute. Thus these permutations are oneway from the point of view of parallel computation.

We study the parallel time-complexity of basic cryptographic primitives such as one-way functions (OWFs) and pseudorandom generators (PRGs). Specifically, we study the possibility of implementing instances of these primitives by NC functions, namely by functions in which each output bit depends on a constant number of input bits. Despite previous efforts in this direction, there has been no con...

9-nitrocamptothecin (9-nc) is a semisynthetic and a low soluble analogue of camptothecin alkaloids that target nuclear enzyme topoisomerase i. the unstable lactone form of 9-nc in biological fluids requires for its cytotoxic activity. to improve aqueous solubility and stability in biological media, 9-nc was loaded in polymeric nanoparticles. in this paper, we studied the effect of peg percent (...

The aimed at all developers users technology to ptovide solutions for various stages design manufacturing. about technol...

objective: there is a large amount of information published about art infants worldwide but apparently the similar data did not published by iranian art centers till now. this study is a comparative study for developmental assessment of these infants. materials and methods: in one case- control study 400 art ' infants have been compared with 420 nc ' infants. their developments have been assess...

Based on the results of Blum, Shub and Smale 1], Meer 5], Cucker and Matamala 3] and Koiran 7], we develop the study of real computation models restricted to additive operations. More speciically we introduce some complexity classes deened by algebraic circuits and we study their relationships with the real computation model. We show that the languages accepted by nonuniform additive circuits o...

The presence of pronounced inequalities in mortality and life expectancy across income, education and social groups has long been a “stylized fact” of demography. Research across a large number of developed and wealthy countries, including Ireland, has shown that those with fewer resources, less education or a lower occupational class have higher standardised mortality rates (SMRs) than more ad...

In order to study circuit complexity classes within NC in a uniform setting we need a uniformity condition which is more restrictive than those in common use Two such conditions stricter than NC uniformity Ru Co have appeared in recent research Immerman s families of circuits de ned by rst order formulas Im a Im b and a unifor mity corresponding to Buss deterministic log time reductions Bu We s...
