AIM： To analyze the diagnostic capabilities of peripapillary retinal nerve fiber layer（p RNFL） thickness and segmented inner macular layer（IML） thickness measured by spectraldomain optical coherence tomography for detection of early glaucoma. METHODS： Fifty-three patients with primary open angle glaucoma（POAG）, 60 patients with normal tension glaucoma（NTG） and 32 normal control subjects were enrolled. Thicknesses of p RNFL, total macular layers（TML）, and the IML, including macular RNFL（m RNFL） and macular ganglion cell layer（m GCL） were assessed. The areas under the receiver operating characteristic curves（AROC） were calculated to compare the diagnostic power of different parameters. RESULTS： There were no differences in the parameters of p RNFL, TML, and IML between POAG and NTG groups. The thicknesses of superior and inferior m GCL showed significant correlation with mean deviation of visual field（R2=0.071, P=0.004; R2=0.08, P=0.002）. The m GCL thickness significantly correlated with the p RNFL thickness in the superior and inferior quadrants（R2=0.156, P〈0.001; R2=0.407, P〈0.001）. The thickness of the inferior-outer sector of macula had greater AROCs than those in the inferior-inner sector of macula. The AROCs for superior（0.894） and inferior（0.879） p RNFL thicknesses were similar with the AROCs for superior（0.839） and inferior m GCL（0.864） thicknesses. Sensitivities at 80% specificity for global p RNFL, inferior-outer m GCL and inferior-outer m RNFL thicknesses were 0.938, 0.867, and 0.725, respectively. CONCLUSION： The diagnostic capability of the m GCL thickness is comparable to that of the p RNFL thickness in patients with early glaucoma. The inferior-outer sector of IML has a better diagnostic capability than the inferiorinner sector of IML for detection of early glaucoma.

Human Action Recognition Based on Dense Trajectories Analysis and Random Forest

引用

Journal of Electronic Science and Technology 2016年第4期14卷 370-376页

作者： pin-Zhong Pan Chung-lin Huang Sonix Technology HsinChu 30265HsinChu Department of M-Commerce and Multimedia Applications Asia UniversityTaichung 41354Taichung

This paper presents a human action recognition method. It analyzes the spatio-temporal grids along the dense trajectories and generates the histogram of oriented gradients （HOG） and histogram of optical flow （HOF） to describe the appearance and motion of the human object. Then, HOG combined with HOF is converted to bag-of-words （BoWs） by the vocabulary tree. Finally, it applies random forest to recognize the type of human action. In the experiments, KTH database and URADL database are tested for the performance evaluation. Comparing with the other approaches, we show that our approach has a better performance for the action videos with high inter-class and low inter-class variabilities.

Dinomischus from the Middle Cambrian Kaili Biota, Guizhou, China

引用

Acta Geologica Sinica(English Edition) 2006年第4期80卷 498-501页

作者： PENG Jin ZHAO Yuanlong lin jih-Pai College of Resource and Environment Engineering Guizhou University Guiyang Guizhou 550003 China State Key Laboratory Palaeobiology and Stratigraphy （NIGP. CAS） Nanjing Jiangsu 210008 China Department of Geological Sciences Ohio State University Columbus OH43210 USA

Dinomischus is a rare solitary epifaunal suspension feeder. The over-all morphology of Dinomischus consists of a conical calyx surrounded with elongate bracts and an elongate stem. Visceral mass and stomach sac are evident in the body cavity. Dinomischus is interpreted as a primative ancestor of living entoprocts based on similarities in morphology and mode of life. Previously, Dinomischus is only known in two localities： the mid-Middle Cambrian Burgess Shale Biota and the Early Cambrian Chengjiang Biota. A single specimen of Dinomischus cf. D. isolatus Cowry Morris, 1977 from the Kaili Biota, Guizhou, China is reported here. The discovery of Dinomischus in the Kaili Biota extends its geographical range and indicated that the rare Dinomischus could tolerate deeper water settings during the Middle Cambrian.

作者： Jianmin Chen Yanan lin pin Liu Shiquan Ruan School of Mathematical Sciences Xiamen UniversityXiamen 361005China Department of Mathematics Southwest Jiaotong UniversityChengdu 610031China

Using the cluster tilting theory,we investigate the tilting objects in the stable category of vector bundles on a weighted projective line of weight type(2,2,2,2).More precisely,a tilting object consisting of rank-two bundles is constructed via the cluster tilting ***,the cluster tilting approach also provides a new method to classify the endomorphism algebras of the tilting objects in the category of coherent sheaves and the associated bounded derived category.

Tensile and compressive behavior of Ti-based bulk metallic glass composites

引用

International Journal of Minerals,Metallurgy and Materials 2013年第6期20卷 582-588页

作者： Yong-sheng Wang Guo-jian Hao Jun-pin lin State Key Laboratory for Advanced Metals and Materials University of Science and Technology Beijing

This article focuses on the tensile and compressive characteristics of a Ti-based bulk metallic glass composite （BMGC）. It is found that the yield stress, maximum strength, and fracture strain are 1380 MPa, 1516 MPa, and 4.3% for uniaxial tension, but 1580 MPa, 4010 MPa, and 29% for uniaxial compression, respectively. The composite displays a linear ＂work hardening＂ capacity under compression; however, the ＂work softening＂ behavior is observed in the true engineering stress-strain curve upon tensile loading. The fracture surfaces of specimens also exhibit dissimilar properties under the different loadings.

Tetraradial symmetry in early poriferans

引用

Chinese Science Bulletin 2014年第7期59卷 639-644页

作者： Joseph P.Botting Xunlai Yuan jih Pai lin State Key Laboratory of Paleobiology and Stratigraphy Nanjing Institute of Geology and Palaeontology Chinese Academy of Sciences

Here is currently little consensus on the branching order and phyletic status of the oldest metazoan groups, but sponges are widely believed to be the earliestbranching living metazoans. Porifera are thought to have diverged before the emergence of developmental characters typical of Eumetazoa, such as well-defined symmetry; extant sponges show radial symmetry of indeterminate high order, or none, combined with polarisation along the axis. In contrast, other early-branching phyla include bilateral and tetraradial(Cnidaria) and biradial(Ctenophora) symmetry, or none(Placozoa). A variety of prismatic early fossil sponges had shown here where the shared symmetry has been overlooked, and also describe structural tetraradial symmetry in Cambrian sponges from South China. Based on this study, this symmetry is likely to have been a primitive feature of sponges, and that the earliest-known fossil sponges were highly organised, cellularly integrated individuals whose body form was under strict genetic control.

作者： Xiang-Jun Xu lin Song Xiao-Ou Jin Dong-Dong Han Xin Wang Jun-pin lin Materials and Chemistry School Zhongyuan University of Technology State Key Laboratory for Advanced Metals and Materials University of Science and Technology Beijing School of Architecture and Engineering Heilongjiang University

Microstructure and microsegregation of directionally solidified Ti-45Al-8Nb alloy were investigated by scanning electron microscopy（SEM）,transmission electron microscopy（TEM） and electron probe microanalyzer（EPMA）.For the alloy solidified at the solidification rates（v） ranging from 10 to 400 μm·s^（-1）,the microstructure of the mushy zone exhibits a cellular-dendritic structure at lower growth rate（v=10-50 μm·s^（-1）） and a typical dendritic morphology at higher growth rate（v = 100-400 μm·s^（-1））.The relationship between primary dendrite arm spacing（λ_1）and v is λ_1=1.08×10~3v^（-0.35）.Al and Nb elements segregate at interdendritic zone and in the dendritic core,*** solid of mushy zone,a relatively flat concentration profile is observed for the typical dendrite structure,and Nb enriches in B2 phase induced by β→α＋β*** content of B2 phase is hardly affected by *** extent of microsegregation in steady-state zone decreases at a lower growth rate because holding the samples at higher temperature after solidification for a long time can homogenize the solid effectively.

A STUDY ON FACTORS FOR RETAILERS IMPLEMENTING CPFR-A FUZZY AHP ANALYSIS

引用

Journal of Systems Science and Systems Engineering 2010年第2期19卷 192-209页

作者： Hsin-pin FU Kuo-Kuang CHU Sheng-Wei lin Chi-Ren CHEN Department of Marketing and Distribution Management National Kaohsiung First University of Science and Technology Kaohsiung (811) Taiwan China Department of Tourism management Shih Chien University Kaohsiung campus (845) Taiwan China Department of Marketing and Logistics Management Far East University Tainan County (744) Taiwan China

Since collaborative, planning, forecasting, and replenishment （CPFR） was first proposed in 1998, numerous studies have focused on exploring its implementation in retailing contexts. While a considerable body of research has emphasized reduced costs, increased sales and improved forecasting ability, there has been a lack of research on the importance of each of the various factors which affect such implementations. In order to find out the critical success factors affecting CPFR implementation, this paper first collected related influence factors regarding adopting CPFR or business to business （B2B） information systems, and further constructed a factor table with a three-layer hierarchical structure. A pair wise analytic hierarchy process （AHP） questionnaire was designed and distributed to experts who were familiar with implementing CPFR in the retailing industry. After questionnaires were returned, we found out the weights of each impact factor by using a fuzzy analytic hierarchy process （fuzzy AHP） approach. The importance of each critical impact factor was investigated, and the paths of the critical success factors were also analyzed. The results of this study can provide more precise information with regard to allocating optimal resources for retailers implementing CPFR.
