A Novel Method for Extracting Information from Web Pages with Multiple Presentation Templates
Qingzhong Li,Yanhui Ding,An Feng,Yongquan Dong
Journal of Software , 2010, DOI: 10.4304/jsw.5.5.506-513
Abstract: Web information extraction is the key part of web data integration. With the need of e-commerce website and the development of web design, web pages with multiple presentation templates arise. The current web information extraction systems are usually based on single presentation template, so web pages with multiple presentation templates can’t be extracted efficiently. This paper focuses on the extraction problem about web pages with multiple presentation templates. Four different kinds of this problem have been considered, and a novel method based on path entropy, presentation regularity and ontology knowledge is presented. The experiment indicates that this method is very promising and it achieves excellent recall and precision.

Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.42022
Abstract: Improving the internal governance is the key factor to promote the development of banking stability, especially for the banks which are just stepping on the right way. This article chose 23 city commercial banks, which had more than 50 billion assets, as the object of study and got the data of them through reading their annual reports from 2008 to 2014 for the empirical study. From the research, we found out that there was no significant relationship between the nature of the bank’s largest shareholder and the banking risk, and the ownership concentration, board size, salary incentive and regional GDP had an opposite relationship with the banking risk, the independent director proportion and banking risk were positively related.

Yanhui Jiang, Junhui Gao
Open Journal of Modern Linguistics (OJML) , 2018, DOI: 10.4236/ojml.2018.84010
Abstract: This research parsed entries of eight contemporary art journals from 1960 to 2015 by Natural Language Processing (NLP) and got 7000 words. These words were then analyzed by three methods: 1) word frequency, 2) word frequency trend analysis based on linear regression, and 3) word frequency variation model analysis based on curve clustering. The data were classified into a five-category set and a ten-category set, along with a ten-word-frequency-variation-model. Based on the above data study, this paper analyzed the resulted trends from political, economical, technological and art perspectives. The conclusion is that hot topics in American contemporary art vary with contemporary social backgrounds.

Nanoscale Research Letters , 2013, DOI: 10.1186/1556-276X-8-118
Abstract: A method for quickly screening and identifying dominant B cell epitopes was developed using hepatitis B virus (HBV) surface antigen as a target. Eleven amino acid fragments from HBV surface antigen were synthesized by 9-fluorenylmethoxy carbonyl solid-phase peptide synthesis strategy, and then CdTe quantum dots were used to label the N-terminals of all peptides. After optimizing the factors for fluorescence polarization (FP) immunoassay, the antigenicities of synthetic peptides were determined by analyzing the recognition and combination of peptides and standard antibody samples. The results of FP assays confirmed that 10 of 11 synthetic peptides have distinct antigenicities. In order to screen dominant antigenic peptides, the FP assays were carried out to investigate the antibodies against the 10 synthetic peptides of HBV surface antigen respectively in 159 samples of anti-HBV surface antigen-positive antiserum. The results showed that 3 of the 10 antigenic peptides may be immunodominant because the antibodies against them existed more widely among the samples and their antibody titers were higher than those of other peptides. Using three dominant antigenic peptides, 293 serum samples were detected for HBV infection by FP assays; the results showed that the antibody-positive ratio was 51.9% and the sensitivity and specificity were 84.3% and 98.2%, respectively. In conclusion, a quantum dot-based FP assay is a very simple, rapid, and convenient method for determining immunodominant antigenic peptides and has great potential in applications such as epitope mapping, vaccine designing, or clinical disease diagnosis in the future.

Abstract: 摘要： 针对常用增量信息提取方法中根据经验阈值确定新旧目标匹配的不足,提出一种导航电子地图中道路网增量信息的多尺度探测方法.该方法用最大类间方差法自适应地确定几何匹配阈值来探测增量信息,完善了基于道路网眼密度的增量变化目标渐进式选取算法,实现了增量信息在较小比例尺下的缩编提取.增量信息探测实验研究结果表明:基于自适应匹配阈值的新旧版本对应路网目标匹配准确率达到了90%,优于传统的经验阈值匹配精度;改进的增量变化目标渐进式选取算法可以满足路网增量更新的结构选取需求.
Abstract: To overcome the disadvantage in matching old and new targets by use of usual experienced threshold value for incremental information extraction, a multi-scale extraction method is proposed for the road network incremental information in navigation electronic map. In this method, an Otsu-based adaptive threshold is adopted to determine the geometric matching criterion so as to detect incremental information; further, a progressive selection algorithm based on the mesh density of road network is improved to extract the incremental change information at a smaller scale in map generalization. Incremental updating test results show that: (1) by use of the Otsu-based adaptive threshold, the matching accuracy between the old-version road objects and new-version ones approximately reaches 90%, which is superior to that by use of the experienced threshold; (2) the improved progressive selection algorithm for incremental updating objects can meet the need of structural selection in road network incremental updating

Abstract: One of the challenges to understand the organization of the nervous system has been to determine how axon guidance molecules govern axon outgrowth. Through an unbiased genetic screen, we identified a conserved Wnt pathway which is crucial for anterior-posterior (A/P) outgrowth of neurites from RME head motor neurons in Caenorhabditis elegans. The pathway is composed of the Wnt ligand CWN-2, the Frizzled receptors CFZ-2 and MIG-1, the co-receptor CAM-1/Ror, and the downstream component Dishevelled/DSH-1. Among these, CWN-2 acts as a local attractive cue for neurite outgrowth, and its activity can be partially substituted with other Wnts, suggesting that spatial distribution plays a role in the functional specificity of Wnts. As a co-receptor, CAM-1 functions cell-autonomously in neurons and, together with CFZ-2 and MIG-1, transmits the Wnt signal to downstream effectors. Yeast two-hybrid screening identified DSH-1 as a binding partner for CAM-1, indicating that CAM-1 could facilitate CWN-2/Wnt signaling by its physical association with DSH-1. Our study reveals an important role of a Wnt-Frz/Ror-Dsh pathway in regulating neurite A/P outgrowth.

Abstract: Transduction of the breast cancer cell line 4T1 with adenoviral vectors encoding the HA117 gene and the green fluorescence protein gene (GFP) (Ad-GFP-HA117), the MDR1 and GFP (Ad-GFP-MDR1) or GFP (Ad-GFP) was respectively carried out. The transduction efficiency and the multiplicity of infection (MOI) were detected by fluorescence microscope and flow cytometry. The transcription of HA117 gene and MDR1 gene were detected by reverse transcription polymerase chain reaction (RT-PCR). Western blotting analysis was used to detect the expression of P-glycoprotein (P-gp) but the expression of HA117 could not be analyzed as it is a novel gene and its antibody has not yet been synthesized. The drug-excretion activity of HA117 and MDR1 were determined by daunorubicin (DNR) efflux assay. The drug sensitivities of 4T1/HA117 and 4T1/MDR1 to chemotherapeutic agents were detected by Methyl-Thiazolyl-Tetrazolium (MTT) assay.The transducted efficiency of Ad-GFP-HA117 and Ad-GFP-MDR1 were 75%-80% when MOI was equal to 50. The transduction of Ad-GFP-HA117 and Ad-GFP-MDR1 could increase the expression of HA117 and MDR1. The drug resistance index to Adriamycin (ADM), vincristine (VCR), paclitaxel (Taxol) and bleomycin (BLM) increased to19.8050, 9.0663, 9.7245, 3.5650 respectively for 4T1/HA117 and 24.2236, 11.0480, 11.3741, 0.9630 respectively for 4T1/MDR1 as compared to the control cells. There were no significant differences in drug sensitivity between 4T1/HA117 and 4T1/MDR1 for the P-gp substrates (ADM, VCR and Taxol) (P < 0.05), while the difference between them for P-gp non-substrate (BLM) was statistically significant (P < 0.05). DNR efflux assay confirmed that the multidrug resistance mechanism of HA117 might not be similar to that of MDR1.These results confirm that HA117 is a strong MDR gene in both HL-60 and 4T1 cells. Furthermore, our results indicate that the MDR mechanism of the HA117 gene may not be similar to that of MDR1.Multidrug resistance (MDR) is a major cause of treat

Abstract: This article aims to introduce how Lego project can help young children with autism spectrum disorder (ASD) improve social interaction and language skills and reduce challenging behaviors. A case study of a preschooler named Adam with mild ASD characteristics such as language delays, behavioral problems and lack of social interaction was introduced, followed by a detailed narration of the intervention sessions using Lego games. A series of self-developed observation checklists were used to monitor Adam’s social emotional development, language development, challenging behaviors as well as fine motor skill development. After three Lego-intervention sessions Adam increases his social interactions with peers, has more eye contact, starts to share materials with his friends, expresses his interest in playing with peers, and improves his verbal communication ability. Besides Lego game, other constructive play materials also can be used to improve Adam and other young children’s with ASD language skills and social competence. The Lego-intervention therapy is also beneficial to typically developing peers in that it can help the development of imagination, creativity and team work.
