Security Tokens and Their Derivatives
The primary purpose of this paper is to model uncertain digital objects in view of nancial risk management in an open network. We have made an abstraction of the objects and deened the security token, which is abbreviated into a word coinage setok. Each setok has its price, values, and timestamp on it as well as the main contents. Not only the price but also the values can be uncertain and may ...
متن کاملConstrained Expressions and their Derivatives
First order logic without quantifiers, a.k.a. zeroth order logic, is more expressive than propositional logic. In this paper, we introduce two new operators for regular expressions allowing us to handle zeroth order boolean formula in order to increase the expressive power of expressions; We also extend the notion of interpretation and of realization using expression interpretation. We thus def...
متن کاملP-48: Infertility and Stress
Background: Infertility is one of the major problems in life which affects about 20% of couples in developed countries and a large population in the developing countries including Iran. Since not much has been discussed, published or talked about in the literature and infertilityconferences in Iran, we have decided to conduct a review of literature and provide a summary of what is known in the ...
متن کاملIsocorydine derivatives and their anticancer activities.
In order to improve the anticancer activity of isocorydine (ICD), ten isocorydine derivatives were prepared through chemical structure modifications, and their in vitro and in vivo activities were experimentally investigated. 8-Amino-isocorydine (8) and 6a,7-dihydrogen-isocorydione (10) could inhibit the growth of human lung (A549), gastric (SGC7901) and liver (HepG2) cancer cell lines in vitro...
متن کاملOn Implicit Image Derivatives and Their Applications
Fast and reliable estimation of image derivatives is among the most fundamental tasks of low level image processing. Implicit finite differences offer much higher spectral resolving efficiency compared to explicit finite differences while the computational effort increases only slightly. Although implicit finite differences had become known to a general audience of numerical mathematicians and ...
