an approach to design and analyze the learning support system based on "learning flow" has been presented from a new perspective according to the chronological processed characteristics with which the learning activities carry out. "Learning flow", inspired by the concept of the "workflow" technology, will be able to provide a new support structure for(More)
BACKGROUND Aberrantly methylated genes represent important markers for cancer diagnosis. We describe a multiplex detection approach to efficiently quantify these markers for clinical applications such as colorectal cancer screening. METHODS Quantitative allele-specific real-time target and signal amplification (QuARTS) combines a polymerase-based target(More)
Lung ischemia–reperfusion injury (LIRI) may occur in the region of the affected lung after reperfusion therapy. Inhaled NO may be useful in treating acute and chronic pulmonary thromboembolism (PTE) due to the biological effect property of NO. A PTE canine model was established through selectively embolizing blood clots to an intended right lower lobar(More)
E74-like factor 5 (Elf5) has been associated with tumor suppression in breast cancer. However, its role in urothelial cancer (UC) is completely unknown. Immunohistochemistry (IHC) and methylation specific PCR (MSP) were done to detect Elf5 expression level and its promoter methylation. Results revealed that low expression of Elf5 on protein and mRNA levels(More)
Lung ischemia-reperfusion injury (LIRI) may occur in the region of the affected lung after reperfusion therapy. The inflammatory response mechanisms related to LIRI in pulmonary thromboembolism (PTE), especially in chronic PTE, need to be studied further. In a PTE model, inflammatory response and apoptosis may occur during LIRI and nitric oxide (NO)(More)
Arts student -oriented computer education for the majority of colleges and universities, is a difficult task. By analyzing the characteristic of the arts students -oriented computer education, a new train of thought that using a computer-assisted assessment and diagnosis system (CAAD) as the learning environment for arts students in order to promote(More)
From virtual learning environment point of view, to establish a supporting system for national teacher education technology training will benefit and solve a series of key issues that the training faced with, meanwhile, it will provide possibility for training assessment. this paper, starting from analyzing key characteristic of our teacher technology(More)
Data analysis and mining is an important paradigm for educational assessment. But most of the existing solutions are based on direct mining of random structured log files. Therefore there exist some key issues like low efficiency, complex calculation formula, and difficult to provide vivid feedback. This paper presents an innovative approach of defining(More)
BACKGROUND Nowadays, small peripheral pulmonary lesions (PPLs) are frequently detected and the prognosis of lung cancer depends on the early diagnosis. Because of the high fee and requiring specialized training, many advanced techniques are not available in many developing countries and rural districts. METHODS Three sets of opaque soft copper wires(More)
According to characteristics of perpendicularity error evaluation of planar lines, Particle Swarm Optimization (PSO) is proposed to evaluate the minimum zone error. The evolutional optimum model and the calculation process are introduced in detail. Compared with conventional optimum methods such as simplex search and Powell method, it can find the global(More)
