Topoisomerases may unknot by recognizing specific DNA juxtapositions. The physical basis of this hypothesis is investigated by considering single-loop conformations in a coarse-grained polymer model. We determine the statistical relationship between the local geometry of a juxtaposition of two chain segments and whether the loop is knotted globally, and ascertain how the knot/unknot topology is...

Picture books are profusely illustrated books in which the illustrations are, to varying degrees, essential to the en joyment and understanding of the story (Tomlinson and Lynch-Brown, 1996). As the most characteristic form of children’s literature (Nodelman, 1996), picture books hold a prominent place in children’s literature because of the juxtaposition of pictures and words. Thanks to the pu...

This paper describes the work that has been done concerning the phonetic transcriptions for the New Dictionary of Italian Anglicisms directed by Prof. Pulcini (University of Turin): the dictionary contains both transcriptions of how Italians pronounce anglicisms and of how the corresponding English words are pronounced by native speakers of English. We shall explain how different pronunciation ...

“A picture is worth a thousand words,” but finding the right thousand words to describe a picture has no simple adage. Camera phones and other mobile devices can easily capture a scene, but processing the image to inform its contents and describe the scene requires efficient object recognition and identification. In an effort to augment reality in a potential virtual museum guide, this document...

Six cases of juxtaposition of the atrial appendages are documented by necropsied specimens and analyzed. A high incidence of conotruncal anomalies, especially transposition of the great arteries, further A-V valve abnormalities, and pulmonary valve atresia, is found. The recognition of juxtaposition of the atrial appendages during cardiac catheterization should alert the investigator to the pre...
