M proteins of the group A streptococcus, despite their well-recognized immunological variations, have the unique capacity of maintaining a common antiphagocytic function for the organism. Antibodies to M proteins, however, are capable of neutralizing the antiphagocytic activity of these molecules (1-3). Although, immunological cross-reactions between different M types have been observed (4-6), ...

ions Mappings The structural component Abstraction here refers to the relation between the domains of the two objects Mapping between the domains of objects is the mathematical tool used to express the abstractions However since abstractions by themselves cannot capture the semantic similarity they have to be associated either with the context Kashyap and Sheth or with extra knowledge in order ...

In this paper we propose a technique for detecting the similarity in the structure of XML documents. The technique is based on the idea of representing the structure of an XML document as a time series in which each occurrence of a tag corresponds to a given impulse. By analyzing the frequencies of the corresponding Fourier transform, we can hence state the degree of similarity between document...

In this paper, we present some studies about relations existing between well known Chomsky string grammars and graph grammars, in particularly hypergraph grammars. We are discussing about deterministic context free Lindenmayer Systems used to describe commands to a device that generates black and white digital images. Instead of well-known methods of drawing, we will paint squares, not lines. A...

The symptoms and signs of severe tinnitus and chronic pain have many similarities and similar hypotheses have been presented regarding how the symptoms are generated. Pain and tinnitus have many different forms. The severity of the symptoms of both varies within wide limits, and it is not likely that all forms have the same pathology. Some individuals with severe tinnitus perceive sounds to be ...

Generalisation of the foundational basis for many-valued logic programming builds upon generalised terms in form of powersets of terms. A categorical approach involving set and term functors as monads allows for a study of monad compositions that provide variable substitutions, and compositions thereof. In this paper, substitutions and unifiers appear as constructs in Kleisli categories related...

In this paper, we present an approach to automatically revealing phonological classes within historically related languages. A newly created bilingual German-Dutch pronunciation dictionary is used for learning phonological similarities between the onsets, nuclei and codas of these two languages via EM-based clustering. Our evaluation is twofold: we apply the models to predict from a German word...

south indian language, culture and civilization, dravidian civilization, is important for many of linguists, anthropologists and archaeologists. so, they are trying to find the origins of it. today, the scholars of civilizations try, however, to find any connection between dravidians culture and their own language and culture. so, they attempt to study in this field. it is clear that the cultur...

As show in 7,230 parent-child pairs (6,726 biological and 504 adoptive), adoptive parents and their adopted children tend to resemble each other in height, weight and fatfolds to an extent paralleling height, weight and fatfold resemblances of natural (biological) parents and their children. Accordingly, the magnitudes of parent-child resemblances commonly given may not be indicative of the ext...
