A large number of 3D models are created and available on the Web, since more and more 3D modelling and digitizing tools are developed for ever increasing applications. The techniques for content-based 3D model retrieval then become necessary. In this paper, a visual similarity-based 3D model retrieval system is proposed. This approach measures the(More)
Electronic Commerce on the Web is thriving, but consumers still have trouble finding products that will meet their needs and desires. AI has offered many kinds of Recommender Systems [11], but they are all oriented toward searching based on concrete attributes of the product (e.g. price, color) or the user (as in Collaborative Filtering). Based on(More)
A case is reported of a 16-month-old girl who presented with generalized hypotonia, ptosis and persistent low grade fever after a previous pneumonia. Brain CT and MRI showed symmetric necrotizing lesions in the basal ganglia, substantia nigra and periaqueduct area. Lactate and pyruvate levels were elevated in both the blood and cerebrospinal fluid. Biopsy(More)
We undertook a prospective ultrasound study of subependymal cyst formation in normal neonates. Twenty five of 500 normal Chinese neonates (5%) were found to have subependymal cysts. Most of these (18 of 25) showed no obvious perinatal insult. This study suggests a rather high incidence of concealed intrauterine subependymal haemorrhage in normal term(More)
UNLABELLED Hypoxic encephalopathy is rarely mentioned as a cause of neurogenic diabetes insipidus (DI) in children. We here report six cases of DI which occurred after severe hypoxic/ischaemic brain damage and include a review of the literature on 28 paediatric cases of neurogenic DI due solely to severe hypoxia/ischaemia. Airway obstruction, haemorrhagic(More)
Fourteen infants or neonates with purulent meningitis underwent prospective brain sonography follow-up for early detection of intracranial complications. Most patients had 12 scans during a 6 month period. The children's ages ranged from 5 days to 11 months. Early surgical intervention is suggested in progressive ventricular dilatation or severe subdural(More)
The reversal of diastolic cerebral blood flow has been regarded as a characteristic waveform of brain death and a useful confirming sign. We report 2 patients who had diastolic flow reversal but survived. One, a 1-month-old boy with status epilepticus, had reversal of diastolic cerebral blood flow detected by Doppler ultrasound soon after admission.(More)
Dental enamel pitting was studied as a diagnostic sign of pediatric tuberous sclerosis (TSC). Thirteen patients aged 2.5 to 18 years with varying degrees of TSC were evaluated. They were checked for the presence of enamel pitting by the use of two to three drops of dental plaque disclosing stain which was applied to the labial surfaces of dry teeth. This(More)
In the world of visual storytelling, narrative development relies on a particular temporal ordering of shots and sequences and scenes. Rarely is this ordering cast in stone. Rather, the particular ordering of a story reflects a myriad of interdependent decisions about the interplay of structure, narrative arc and character development. For storytellers,(More)
