Definiteness expresses a constellation of semantic, pragmatic, and discourse properties—the communicative functions—of an NP. We present a supervised classifier for English NPs that uses lexical, morphological, and syntactic features to predict an NP's communicative function in terms of a language-universal classification scheme. Our classifiers establish(More)
We present a definiteness annotation scheme that captures the semantic, pragmatic, and discourse information associated with noun phrases, which we call communicative functions. A survey of the linguistics literature suggests that definiteness does not express a single communicative function but is a grammaticalization of many such functions, for example,(More)
Staphylococcus epidermidis septicemia and pneumonia developed in an 18-year-old male undergoing bone marrow transplantation. The organism was isolated from multiple blood cultures, sputum cultures, an indwelling catheter tip and post-mortem lung biopsy specimens. The bacterium was resistant to penicillin, erythromycin, clindamycin, chloramphenicol,(More)
BACKGROUND Clinical immunotherapy trials using DCs depend on large-scale methods for DC generation that fulfil current good manufacturing practice requirements. Our goal was to develop data on two variables, monocyte-enrichment method and culture container, which could be used to design a closed-system process for ex vivo generation of immature DCs. (More)
Piezoelectric sensors have been shown to respond reproducibly to changes in tissue mechanical properties surrounding an implant over a 4-month period. The vibrational amplitude at a frequency corresponding to the radial resonance shows a statistically significant change over time. The initial period of inflammation is marked by a significant reduction in(More)
Serum phosphodiesterase I (PDE I) activity was determined in 13 control and 51 breast-cancer patients with various stages of disease. Patients with both localized and metastatic breast cancer had significantly elevated serum PDE I activity. The highest activity was seen in patients with liver metastases. A decline in serum PDE I activity was seen after(More)
VP 16-213, an antineoplastic, semisynthetic podophyllotoxin derivative, inhibits NBT reduction in the polymorphonuclear neutrophil (PMN). In the resting PMN an almost complete inhibition is seen at a concentration of 170 microM and a partial inhibition is seen at 17 microM. In PMN's stimulated with zymosan activated serum, partial inhibition is seen at(More)
The isopropanol precipitation test is widely used for the detection of unstable hemoglobins. A method for accurately and easily determining the amount of hemoglobin precipitated is described. This study demonstrates that changes in incubation time, pH, temperature, and isopropanol and hemoglobin concentrations affect the precipitation of oxy Hb A and oxy Hb(More)
The molecular stability and function of hemoglobin (Hb) Hasharon (alpha 2 H beta 2) and Hb Hasharon2 (alpha 2 H delta 2) were studied and compared to Hbs A, A2 and S. Hb Hasharon and Hb Hasharon2 had slightly lower P50 values than Hb A and Hb A2 but had normal responses to organic phosphates. The molecular stability of Hb Hasharon and Hb Hasharon2 (as(More)
Cord blood angiotensin-I-converting enzyme (ACE) activity was examined in 21 term and 21 premature infants. Values were significantly higher in premature infants than in term infants. Cord blood ACE activity was found to have a significant negative correlation with birth weight and gestational age. ACE activity measured from peripheral blood during the(More)
