To aim at the evaluation task of CLP2012 named entity recognition and disambigua-tion in Chinese, a Chinese name disam-biguation method based on adaptive clustering with the attribute features is proposed. Firstly, 12-dimensional character attribute features is defined, and tagged attribute feature corpus are used to train to obtain the recognition model of(More)
This study aimed to evaluate factors associated with significant liver histological changes. Liver biopsies from 157 CHB patients were retrospectively analyzed. Only ALB was significantly correlated with advanced liver necroinflammatory (P = 0.001). Age, ALB, GLOB, AST, PLT, and PT were independent predictors of significant fibrosis (P = 0.002, P < 0.001, P(More)
A scheme of integrated guidance/autopilot design for missiles with impact angle constraints is studied in this paper. When the integrated guidance/autopilot model yaw plane is formulated, the guidance/control law with impact angel constraints is designed based on the backstepping idea and VSC theory. For the unavailable information of the maneuvering(More)
One water-soluble polysaccharide (ABP-W1) was purified from the fruiting bodies of Agaricus blazei by DEAE Sepharose Fast Flow and Sepharose 6 Fast Flow column chromatography. Its molecular weight was about 3.9×10(2) kDa as determined by high-performance size-exclusion chromatography (HPSEC). The structural feature of ABP-W1 was investigated by a(More)
In this article, we report a rare case of double aortic arch. The case presented initially with a foreign object in the oesophagus. The patient was a 2-year-old boy, who was referred with primary symptoms of tussis (15 days) and emesis (2 days). He had a history of ingesting a coin. Routine chest X-ray indicated a rounded, metal foreign object in the upper(More)
Bused on hypothesis testing, methods of sensor management used in target detection and localization are studied. The detector used in this problem can operate in "focused mode" and "broad search mode". The former offers higher detection and localization accuracy but less coverage area than the latter. It is supposed that a signal source is to be detected(More)
