Ontology languages like OWL allow for semantically rich annotation of resources, such as products advertised at an electronic online marketplace, while the Description Logic (DL) formalism underlying OWL provides reasoning techniques to perform matchmaking on such annotations. We identify peculiarities in the use of DL inferences for matchmaking which are due to the open-world semantics of OWL,...

Exercise 1. Let G be a group, equipped with the structure of a C∞-manifold. Let μ : G×G→ G, (x, y) 7→ xy be the multiplication map. We assume that μ is smooth, i.e., C∞. (a) Show that the tangent map T(e,e)μ : TeG×TeG→ TeG of μ at (e, e) is given by (X,Y ) 7→ X + Y. Hint: use partial derivatives with respect to x and y. (b) Show that the inversion map ι : G → G, x 7→ x−1 is smooth in an open ne...

Online communities have become become a crucial ingredient of e-business. Supporting open social networks builds strong brands and provides lasting value to the consumer. One function of the community is to recommend new products and services. Open social networks tend to be resilient, adaptive, and broad, but simplistic recommender systems can be 'gamed' by members seeking to promote certain p...

Although vitamin E has been known as an essential nutrient for reproduction since 1922, we are far from understanding the mechanisms of its physiological functions. Vitamin E is the term for a group of tocopherols and tocotrienols, of which alpha-tocopherol has the highest biological activity. Due to the potent antioxidant properties of tocopherols, the impact of alpha-tocopherol in the prevent...

Reading is a hobby to open the knowledge windows. Besides, it can provide the inspiration and spirit to face this life. By this way, concomitant with the technology development, many companies serve the e-book or book in soft file. The system of this book of course will be much easier. No worry to forget bringing the photoperiod and testicular function in phodopus sungorus book. You can open th...

Let Ω = R 3 ∖ K ¯, where is an open bounded domain with smooth boundary Γ. V ( t ) e G b , ⩾ 0, be the semigroup related to Maxwell’s equations in dissipative condition ν ∧ E + γ x H > ∀ ∈ We study case when ≠ 1, Γ, and we establish a Weyl formula for counting function of eigenvalues polynomial neighbourhood negative real axis.

Background & Aim:Cognitive impairment is one of the age-related mental problems and a typical indicator of neurodegeneration. Eragrostis tremula Hochst. ex Steud. is a commonly used medicinal plant in Nigeria for memory enhancement. This study, therefore, aimed at evaluating the memory-enhancing potential of aqueous ethanolic extract of E. tremula in ...

Various methods are needed to extract information from current (digital) comics. Furthermore, the use of different (proprietary) formats by comic distribution platforms causes an overhead for authors. To overcome these issues, we propose a solution that makes use of the EPUB 3 specification, additionally leveraging the Open Web Platform to support animations, reading assistance, audio and multi...
