the concept of  -semihyperring is a generalization of semiring, a generalization of semihyperring and a generalization of      -semiring. since the theory of ideals plays an important role in the theory of  - semihyperring, in this paper, we will make an intensive study of the notions of noetherian, artinian, simple and   regular      -semihyperrings. the bulk of this paper...

Recently, many approaches have been proposed for building simple symbolic proofs of cryptographic protocols with computational soundness. However, most of them support only bare-bone execution model without any ideal setup, such as the existence of authenticated channel, and only deterministic protocols. Thus many protocols are not expressible in those models. Following the work of Canetti and ...

Background: Mentorship develops a personal relationship in which a more experienced and knowledgeable person helps a less experienced person. In this study we aimed to investigate mentorship status and its impact from viewpoint of clinical professors of Shiraz medical school. Methods: In this cross-sectional study 99 clinical professors of medicine at Shiraz medical school were investigated usi...

the aim of this paper is to introduce and study set- valued homomorphism on lattices and t-rough lattice with respect to a sublattice. this paper deals with t-rough set approach on the lattice theory. the result of this study contributes to, t-rough fuzzy set and approximation theory and proved in several papers. keywords: approximation space; lattice; prime ideal; rough ideal; t-rough set; set...

L2 motivation research has a longstanding monolingual bias. Recently, however, the motivational systems of a multilingual’s different languages have been conceptualized as constituting a multilingual motivational system, and it has been suggested that interactions between the ideal Lx self and the ideal Ly self can lead to the emergence of an ideal multilingual self. While the notion of an idea...

Gentry proposed a fully homomorphic public key encryption scheme that uses ideal lattices. He based the security of his scheme on the hardness of two problems: an average-case decision problem over ideal lattices, and the sparse (or “low-weight”) subset sum problem (SSSP). We provide a key generation algorithm for Gentry’s scheme that generates ideal lattices according to a “nice” average-case ...

A characteristic of African pre-transitional fertility regimes is large ideal family size. This has been used to support claims of cultural entrenchment of high fertility. Yet in Kenya fertility rates have fallen. In this paper this fall is explored in relation to trends in fertility norms and attitudes using four sequential cross-sectional surveys spanning the fertility transition in Kenya (19...
