This article presents a systemic method to generate and map an optimal virtual topology onto a certain physical wide area optical fiber network so as to maximize the scaleup which provides an estimate of the network throughput. The problem is to find the best possible virtual topology over a given wavelength-routed all-optical physical topology for wide area coverage. The physical topology cons...

Let $D$ be an integral domain and $star$ a semistar operation stable and of finite type on it. We define the semistar dimension (inequality) formula and discover their relations with $star$-universally catenarian domains and $star$-stably strong S-domains. As an application, we give new characterizations of $star$-quasi-Pr"{u}fer domains and UM$t$ domains in terms of dimension inequal...

Background: Protein-protein interactions do not provide any direct information re‌garding the domains within the proteins that mediate the interactions. The majority of proteins are multi domain proteins and the interaction between them is often defined by the pairs of their domains. Most of the former studies focus only on interacting do‌main pairs. However they do not consider the in...

due to high speed computer networks, the use of digitally formatted data has increased many folds.the digital data can be duplicated and edited with great ease which has led to a need for effectivecopyright protection tools. digital watermarking is a technology of embedding watermark withintellectual property rights into images, videos, audios and other multimedia data by a certainalgorithm .di...

introduction: recent studies suggest that endocytosis of romk channels is important for regulation of k+ secretion in cortical collecting ducts. in this study the effect of v364d mutation is examined on the membrane turnover and stability of romk2 channel when expressing in xenopus laevis oocytes. materials and methods: in this experimental study, oocytes were isolated by standard protocols usi...

This paper introduces a formal model of internal constraints that derives the link between initial disadvantage with aspirations and choices. We show how the cognitive windows of individuals are endogenously determined and show how an individual’s cognitive neighbors impacts on internal constraints. Our analysis suggests that accounting for poverty traps requires an account of how the external ...

the domain of the qur’an has been one of the issues which have raised various viewpoints among the muslim scholars, particularly in recent decades that it has been more widely welcomed due to the muslims increasing attention to their revealed book and their encountering with the views of other religions and schools. in this respect, three viewpoints can be clearly seen among the muslim thinkers...
