BACKGROUND Although many studies have suggested that biomass smoke is a risk factor for COPD, the relationship between the two has not been firmly established. In particular, the extent of the association between exposure of biomass smoke and COPD in different populations, as well as the relationship between biomass smoke and cigarette smoke, is not clear.(More)
This paper is concerned with automatic extraction of titles from the bodies of HTML documents. Titles of HTML documents should be correctly defined in the title fields; however, in reality HTML titles are often bogus. It is desirable to conduct automatic extraction of titles from the bodies of HTML documents. This is an issue which does not seem to have(More)
A maximum entropy based model for prosody phrase break prediction was proposed in this paper, and a comparison was conducted on large corpora between the new model and the decision tree based model which was the mainstream method for prosody phrase break prediction. The contribution of lexical information and influences of different cutoff values were also(More)
Cloze-style queries are representative problems in reading comprehension. Over the past few months, we have seen much progress that utilizing neural network approach to solve Cloze-style questions. In this paper, we present a novel model called attention-over-attention reader for the Cloze-style reading comprehension task. Our model aims to place another(More)
OBJECTIVE To evaluate the effects of a community based integrated intervention for early prevention and management of chronic obstructive pulmonary disease (COPD) in China. DESIGN Cluster randomised controlled trial. SETTING Eight healthcare units in two communities. PARTICIPANTS Of 1062 people aged 40-89, 872 (101 with COPD and 771 without COPD) who(More)
This paper presents two new ideas for text dependent mispronunciation detection. Firstly, mispronunciation detection is formulated as a classification problem to integrate various predictive features. A Support Vector Machine (SVM) is used as the classifier and the loglikelihood ratios between all the acoustic models and the model corresponding to the given(More)
Integration of viral-DNA into host chromosome mediated by the viral protein HIV-1 integrase (IN) is an essential step in the HIV-1 life cycle. In this process, human protein Lens epithelium-derived growth factor (LEDGF/p75) is discovered to function as a cellular co-factor for integration. LEDGF/p75-HIV-1 IN interaction represents an attractive target for(More)
In this paper we address the problem of entity search. Expert search and time search are used as examples. In entity search, given a query and an entity type, a search system returns a ranked list of entities in the type (e.g., person name, time expression) relevant to the query. Ranking is a key issue in entity search. In the literature, only expert search(More)
OBJECTIVE To determine whether the pneumonia severity index (PSI) can predict in-hospital mortality for AECOPD patients and compare its usefulness with the CURB65 and BAP65 indexes to predict mortality. METHODS Demographics, clinical signs and symptoms, comorbidities, and laboratory and radiographic findings of hospitalized AECOPD patients were obtained.(More)
BACKGROUND Epidemiological research and meta-analyses of published data have shown that biomass smoke (BS) is a risk factor for chronic obstructive pulmonary disease (COPD). However, the link between BS and COPD lacks experimental confirmation. OBJECTIVES To verify whether BS can induce pathologic changes and systemic oxidative stress, which may be(More)
