In this paper, we propose to introduce syntactic classes in a lexicalized dependency formalism. Subcategories of words are organized hierarchically from a general, abstract level (syntactic categories) to a word-specific level (single lexical items). The formalism is parsimonious, and useful for processing. We also sketch a parsing model that uses the(More)
BACKGROUND Although home parenteral nutrition (HPN) is often indicated in cancer patients, many physicians are concerned about the risks potentially associated with the use of central venous access devices (VADs) in these patients. The aim of this prospective study was to investigate the actual incidence of VAD-related complications in cancer patients on(More)
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)
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 patients(More)
The study of canine vaginal cytology underwent limited evolution over the years. Presence and significance of inflammatory cells in vaginal smears are little considered aspects in the bitch. Moreover, occurrence of vaginal bacteria in breeding bitches during follicular phase of the reproductive cycle, in absence of clinical signs of infection, involves the(More)
An 84-year-old male with degeneration of a radiolucent mitral bioprosthesis was successfully treated with transapical valve-in-valve implantation exclusively guided by transesophageal echocardiography. The techniques involved in performing this procedure are reviewed.
Despite many advances in prevention and perioperative care, deep sternal wound infection (DSWI) remains a pressing concern in cardiac surgery, with a still relevant incidence and with a considerable impact on in-hospital mortality and also on mid- and long-term survival. The permanent high impact of this complication is partially related to the increasing(More)
A non-invasive approach to define grafts patency and stenosis in the follow-up of coronary artery bypass graft (CABG) patients may be an interesting alternative to coronary angiography. 64-slice-coronary computed tomography is nowadays a diffused non-invasive method that permits an accurate evaluation of coronary stenosis, due to a high temporal and spatial(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)
