Named entities form the major components in a document. When we catch the fundamental entities, we can understand a document to some degree. This paper employs different types of information from different levels of text to extract named entities, including character conditions, statistic information, titles, punctuation marks, organization and location(More)
Recently, language barrier becomes the major problem for people to search, retrieve, and understand WWW documents in different languages. This paper deals with query translation issue in cross-language information retrieval, proper names in particular. Models for name identification, name translation and name searching are presented. The recall rates and(More)
PURPOSE The use of SPECT phase analysis to optimize left-ventricular (LV) lead positions for cardiac resynchronization therapy (CRT) was performed at baseline, but CRT works as simultaneous right ventricular (RV) and LV pacing. The aim of this study was to assess the impact of RV apical (RVA) pacing on optimal LV lead positions measured by SPECT phase(More)
Infiltrating angiolipomas are rarely encountered in the spine. We present a case involving a 71-year-old man with a dorsal epidural angiolipoma at the T5-T7 level. The tumor involved the T5-T6 vertebral bodies and left pedicle. The patient presented with acute paraparesis and MRI showed a homogeneously hyphointense lesion on T1-weighted images. The epidural(More)
INTRODUCTION In patients with unresectable HCC, transcatheter arterial chemoembolization (TACE) is a widely used treatment. Recently, as an alternative treatment modality for HCC, transcatheter arterial embolization with radioisotopes has been investigated. In this study, we compared the therapeutic efficacy of an intra-hepatic arterial injection of(More)
OBJECTIVE In our recent study, we developed a new radiopharmaceutical (Re-188 MN-16ET lipiodol) with encouraging results for the treatment of liver malignancy. In this study, we further evaluated the therapeutic efficacy of this radiopharmaceutical by measuring tumor response and survival times in rats with liver tumors after intra-hepatic arterial(More)
The gold nanoparticles with core diameter of 3.9-4.7 nm were stabilized with octanethiolate and dipyridylphosphinicamido undecanethiolate. Without varying the size of central Au cores, palladium complexes were immobilized onto these Au nanoparticles through chelation to the surface-bound dipyridyls. Hybrid catalysts of this type were dissolvable and(More)
BACKGROUND : Bladder irrigation and retrograde filling technique has been used to reduce urinary F-18 FDG (FDG) activity for better image interpretation in patients with pelvic tumors. Despite the zealous use of this technique, FDG accumulation in the urinary bladder has been reported and might cause false-positive or false-negative results. In this study,(More)
The Diels-Alder reaction rate constants of methyl vinyl ketone with cyclopentadiene and cyclohexadiene in the presence of a novel organotungsten catalyst, [P(2-py)(3)W(CO)(NO)(2)](2+), have been measured experimentally and modeled theoretically at several temperatures. The uncatalyzed systems were also studied for direct comparison. When 0.0022 M of(More)
