The Internet of Things (IoT) paradigm, extending the computing and communicating capabilities to virtually every object, raises many new challenges to IoT-enabling systems. At the middleware layer, a context aware adaptive component has to fit the requirements and constraints for different applications, deal with heterogeneous data, be scalable to large(More)
In this paper, we propose to introduce syntactic classes in a lexicalized formalism like dependency. Subcategories of words are organized hierarchically from a general, abstract level (syntactic categories) to a word-speciic level (single lexical items). The formalism is linguistically perspicuous, and useful for processing. A parsing model is deened, that(More)
PURPOSE Few prospective follow-up studies evaluating the use of peripherally inserted central catheters (PICCs) to deliver chemotherapy and/or home parenteral nutrition (HPN) have focused exclusively on oncology outpatients. The aim of this prospective study was to assess the reliability and the safety of PICCs over a 5-year use in non-hospitalized cancer(More)
This paper proposes a hierarchical organization of the linguistic knowledge, that views grammar as an abstraction of item-dependent information (in particular, an abstraction of subcategorization frames into a hierarchy of classes). The formalism has been successfully applied to a classiication of 105 Italian verbal frames, developed by analysing a corpus(More)
Much recent work in computational linguistics emphasizes the role of lexical information in syntactic representation and processing. In this paper, I propose to represent syntax as an abstraction of subcategorization frames, from a word-speciic level to a general, abstract level (syntactic categories). The representation is linguistically perspicuous, and(More)
BACKGROUND Recent data have highlighted a higher rate of neurological injuries in minimal invasive mitral valve surgery (MIMVS) compared with the standard sternotomy approach; therefore, the role of specific clamping techniques and perfusion strategies on the occurrence of this complication is a matter of discussion in the medical literature. The purpose of(More)
BACKGROUND Intensivists and cardiothoracic surgeons are commonly worried about surgical site infections (SSIs) due to increasing length of stay (LOS), costs and mortality. The antimicrobial prophylaxis is one of the most important tools in the prevention of SSIs. The objective of this study was to investigate the relationship between the timing of(More)
