The Library of Babel, described by Jorge Luis Borges, stores an enormous amount of information. The Library exists ab aeterno. Wikipedia, a free online encyclopaedia, becomes a modern analogue of such a Library. Information retrieval and ranking of Wikipedia articles become the challenge of modern society. While PageRank highlights very well known nodes with many ingoing links, CheiRank highlig...

The qualitative and quantitative composition of the floral odour of Peltandra uirginica was determined by trapping odour components from freshly cut inflorescences on Tenax and Carbotrap adsorbents using a purge and trap apparatus. Analysis showed that a single novel compound, 1,3,6-trimethyl-2,5-dioxabicyclo[3.2.l.]nonane, comprised nearly 70% of the odour. Four isomers of this compound were f...

This study was conducted to evaluate the frequency of FV1691 G-A, FV4070 A-G, PT20210 G-A, EPCR 23 gene bp insertion and ACE gene 300 bp deletion among healthy Egyptians. One hundred and eighty eight healthy Egyptians were included to the study. Previously reported molecular techniques were used for the determination of mutations. Thirthy one individuals had FV1691 G-A (16.5%) mutation with an ...

In this paper we examine story-driven interactive spaces and argue that story development requires centralized control of the actions of the characters that inhabit such environments. This argument leads us to propose the story-character-device (SCD) architecture that, unlike previous approaches, separates the locus of story control in a distinct software module. To exemplify the use of the arc...

firdausi shahnameh has been illustrated more than any other literary work in the history of persian paintings. so far, many studies have been carried out on these historical paintings of shahnameh. most of these studies have been formalistic and have been considered to be merely representational works of written text. those studies have been focused on form, performing techniques and style clas...

We define analytic torsion τ (X,E ,H) ∈ detH(X, E ,H) for the twisted de Rham complex, consisting of differential forms on a compact Riemannian manifold X valued in a flat vector bundle E , with a differential given by ∇ +H ∧ · , where ∇ is a flat connection on E , H is an odd-degree closed differential form on X, and H(X, E ,H) denotes the cohomology of this Z2-graded complex. We show that whe...
