In this paper, we present a new method to improve the performance of current bag-of-word based image classification process. After feature extraction, we introduce a pair wise image matching scheme to select the discriminative features. Only the label information from the raining-sets is used to update the feature weights via an iterative matching(More)
OBJECTIVE To investigate the efficacy and safety of standard-dose versus high-dose imatinib. METHODS After a systematic review of English language articles, five studies including 2008 patients were eligible for the meta-analysis. Data extracted from each study were synthesized into overall odds ratios (OR). RESULTS The overall OR for the high dose vs(More)
Thirty-two patients in whom Legg-Perthes disease apparently involved only one hip were examined with venography, measurement of intraosseous and intra-articular pressures, arthrography, and dynamic triphasic bone-imaging with 99mTc methylene diphosphonate. The arterial flow of blood in the affected femoral head was slightly decreased, but the difference(More)

Since January, 1980, the Shanyang Family Planning Research Institute in China has used a crystal trichosanthin protein (CTP) compound for abortions of 5-16 week pregnancies. A study was made of 7754 abortions conducted up to June 1989 with a success rate of 95.5-96.4%. The participants of the study included women who had medical contraindications for(More)
In modern China the investigation and treatment of scoliosis began in the late 1970s. The incidence of scoliosis in the Chinese population of the Sichuan province was 0.064%, and the incidence of >10 degrees for Beijing students was 1.04%. The surgical treatment of scoliosis for 2122 patients reported in the Chinese literature was reviewed by the authors.(More)
Simulation of 3D garment is important in e-commerce, which can help a consumer to select a fitting dress. The existing systems use the finite element technique to create the simulation model, and the costing time is usually too long for consumers to wait. In this paper, a new simulation method based on six pieces of Bezier curved surfaces is presented,(More)
Nodes in wireless Ad Hoc networks often encounter spatially-correlated contention, where multiple nodes in the same neighborhood all sense an event they need to transmit information about. The IEEE 802.11 DCF protocol can lead to severe unfairness, i.e., some nodes seize the whole channel capacity while others are starved. It is found that the main reason(More)
