Fast implementation of kernel simplex volume analysis based on modified Cholesky factorization for endmember extraction

引用

Frontiers of Information Technology & Electronic Engineering 2016年第3期17卷 250-257页

作者： Jing li Xiao-run li li-jiao wang liao-ying ZHAO College of Electrical Engineering Zhejiang University Institute of Computer Application Technology Hangzhou Dianzi University

Endmember extraction is a key step in the hyperspectral image analysis process. The kernel new simplex growing algorithm （KNSGA）, recently developed as a nonlinear alternative to the simplex growing algorithm （SGA）, has proven a promising endmember extraction technique. However, KNSGA still suffers from two issues limiting its application. First, its random initialization leads to inconsistency in final results; second, excessive computation is caused by the iterations of a simplex volume calculation. To solve the first issue, the spatial pixel purity index （SPPI） method is used in this study to extract the first endrnember, eliminating the initialization dependence. A novel approach tackles the second issue by initially using a modified Cholesky fac- torization to decompose the volume matrix into triangular matrices, in order to avoid directly computing the determinant tauto- logically in the simplex volume formula. Theoretical analysis and experiments on both simulated and real spectral data demonstrate that the proposed algorithm significantly reduces computational complexity, and runs faster than the original algorithm.

China＇s regional transport dominance： Density, proximity, and accessibility

引用

Journal of Geographical Sciences 2010年第2期20卷 295-309页

作者： JIN Fengjun wang Chengjin li Xiuwei wang jiao＇e Institute of Geographic Sciences and Natural Resources Research CAS Beijing 100101 China

Transport infrastructure plays an important role in shaping the configuration of spatial socio-economic structures and influences regional accessibility. This paper defines transport dominance from three aspects： quafity, quantity, and advantage, measured by density, proximity, and accessibility indices. County is the basic unit for analysis. The results reveal：（1） Transport dominance statistically follows a partial normal distribution. A very few counties, 1.4% of the total, have extremely high transport dominance which strongly supports the socio-economic development in these areas. In contrast, one eighth of all counties have poor transport dominance which impedes local socio-economic development to some extent. The remaining areas, about 70% of the counties, have median transport dominance. （2） Transport dominance is spatially unevenly distributed, with values decreasing gradually from the coastal area to the inland area. Areas in the first-highest level of transport dominance are mainly concentrated in the Yangtze River Delta, the Greater Beijing area, and the Pearl River Delta. Areas in the second-highest level are focused in Chengdu, Chongqing, and Wuhan metropolitan areas. Provincial capitals and a few other counties belong to the third-highest level.

Anti-CD69 monoclonal antibody treatment inhibits airway inflammation in a mouse model of asthma

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2015年第7期16卷 622-631页

Objective： Airway inflammation and airway hyper-responsiveness（AHR） are principle pathological manifestations of asthma. Cluster of differentiation 69（CD69） is a well-known co-stimulatory factor associated with the activation, proliferation as well as apoptosis of immune cells. This study aims to examine the effect of anti-CD69 monoclonal antibody（m Ab） on the pathophysiology of a mouse model of asthma. Methods： A murine model of ovalbumin（OVA）-induced allergic airway inflammation was used in this study. Briefly, mice were injected with 20 μg chicken OVA intraperitoneally on Days 0 and 14, followed by aerosol provocation with 1%（0.01 g/ml） OVA on Days 24, 25, and 26. Anti-CD69 m Ab or isotype Ig G was injected intraperitoneally after OVA challenge; dexamethasone（DXM） was administrated either before or after OVA challenge. AHR, mucus production, and eosinophil infiltration in the peribronchial area were examined. The levels of granulocyte-macrophage colony-stimulating factor（GM-CSF） and interleukin-5（IL-5） in bronchoalveolar lavage fluid（BALF） were also assayed as indices of airway inflammation on Day 28 following OVA injection. Results： Pretreatment with DXM together with anti-CD69 m Ab treatment after OVA provocation completely inhibited AHR, eosinophil infiltration and mucus overproduction, and significantly reduced BALF IL-5. However, treatment with DXM alone after OVA challenge only partially inhibited AHR, eosinophil infiltration and mucus overproduction, and did not diminish BALF IL-5. Treatment with either DXM or anti-CD69 m Ab did not alter the concentration of BALF GM-CSF. Conclusions： Anti-CD69 m Ab treatment inhibits established airway inflammation as effectively as DXM pretreatment. This study provides a potential alternative therapeutic opportunity for the clinical management of asthma and its exacerbation.
