eleven years of age. He was admitted to the pediatric service for evaluation of splenomegaly of marked degree. Birth, neonatal and developmental history revealed no abnormalities. The family history was non-contributory. During the year prior to admission the boy experienced intermittent jaundice of mild degree. There was no history of hematemesis or melena. Five months prior to admission enlarged tonsils and adenoids had been removed without en-suing complication, Physical examination revealed a small, pale, poorly nourished boy exhibiting retarded physical development. Marked abdominal enlarge-ment, moderate ascites and distended superficial abdominal veins were noted. The superficial lymph nodes were slightly enlarged. The liver extended 9 cm. below the costal margin; the spleen was greatly enlarged and could be palpated 22 cm. below the costal margin in the midline. A soft systolic murmur was audible at the left sternal border. The chest appeared normal and x-ray examination did not reveal cardiac enlargement; the lung fields were normal. The blood pressure was 116/52. No tel-angiectases were visible in the skin or mucous membranes. Studies of the peripheral blood and bone marrow revealed microcytic anemia and lymphocytosis with-out evidence of immaturity. The hemoglobin was 9.2 gm./lOO ml., the erythrocyte count was 5.85 mil-lion/cu. mm.; leukocytes numbered 6,200 cells/cu. mm., with 49 per cent polymorphonuclear cells, 46 per cent lymphocytes, 2 per cent monocytes and 2 per cent eosinophils. Erythrocyte fragility, bleeding time, coagulation time and prothrombin time were all within normal limits. An evaluation of liver function showed normal values for serum bilirubin, urine urobilinogen and galactose tolerance but the cephalin-cholesterol flocculation test was 4 plus. The clinical impression was Banti’s syndrome associated with hepatic disorder. Portal hypertension was assumed University of to be present, although esophageal varices could not when he was be demonstrated by x-ray examination. Splenectomy of Pathology and Medicine, University of Minnesota, School of Medicine, Minneapolis, was supported in part by a contract from the office of the Surgeon General, United States

N2 - We (2002) have investigate how to use Gaussian mixture continuous-density hidden Markov models (CDHMMs) for handwritten Chinese character modeling and recognition. We have identified and developed a set of techniques that can be used to construct a practical CDHMM-based off-line recognition system for a large vocabulary of handwritten Chinese characters. We have reported elsewhere the key techniques that contribute to the high recognition accuracy. In this paper we describe how to make our recognizer compact without sacrificing too much of the recognition accuracy. We also report the results of a series of experiments that were performed to help us make a good decision when we face several design choices.
