This chapter describes an experimental computer program that deduces the meaning of novel verbs from the context of story descriptions. The key idea is a variation on Winston's (Winston, 1975) program that learned the structural descriptions of block world scenes. Instead of learning descriptions of toy block assemblies like ARCH and TOWER, the word-learning program acquires frame-based descrip...

With the wide-world expansion of the social web, subjectivity analysis became lately one of the main research focus in the area of intelligent information retrieval. Being able to find out what people feel about a specific topic, be it a marketed product, a public person or a political issue, represents a very interesting application for a large class of actors, from the everyday product and se...

Few morphological differences have been identified so far that distinguish the human brain from the brains of our closest relatives, the apes. Comparative analyses of the spatial organization of cortical neurons, including minicolumns, can aid our understanding of the functionally relevant aspects of microcircuitry. We measured horizontal spacing distance and gray-level ratio in layer III of 4 ...

Barium/Calcium profiles of bivalve shells are characterized by flat background signals periodically interrupted with sharp peaks, with the background signals correlated with water Ba/Ca. To test if the peaks are an environmental signal related to productivity, we analyzed high resolution Ba/Ca profiles in bivalve shells that grew adjacent to one another. Two aragonitic Saxidomus giganteus show ...

Influence of bronchial asthma (BA) severity on physical development in children patients was evaluated in comparison with healthy population. Materials and Methods. 1042 children and adolescents (768 boys) with atopic BA were evaluated. All children underwent standard examination in a clinical setting, including anthropometry. The control group included 875 healthy children of a comparable age ...

Betulinic acid (BA), a pentacyclic triterpene, represents a new therapeutic substance that has potential benefits for treating glioblastoma. Recently, new strategies for producing BA derivatives with improved properties have evolved. However, few studies have examined the combination of BA or BA derivatives using radiotherapy. The effects of two BA derivatives, NVX-207 and B10, on cellular and ...
