    Sensors Magazine 14(10):18114 (2014) PMID 25268913 PMCID PMC4239905

    The brown rice plant hopper (BRPH), Nilaparvata lugens (Stal), is one of the most important insect pests affecting rice and causes serious damage to the yield and quality of rice plants in Asia. This study used bionic electronic nose technology to sample BRPH volatiles, which vary in age and amo...
  4. Improved algorithms for the classification of rough rice using a bionic electronic nose based on PCA and the Wilks distribution.

    Sensors Magazine 14(3):5486 (2014) PMID 24651725 PMCID PMC4004003

    Principal Component Analysis (PCA) is one of the main methods used for electronic nose pattern recognition. However, poor classification performance is common in classification and recognition when using regular PCA. This paper aims to improve the classification performance of regular PCA based ...
  5. Rice plant-hopper infestation detection and classification algorithms based on fractal dimension values and fuzzy C-means

    Mathematical and Computer Modelling 58(3-4):701 (2013)

    Rice plant-hopper (RPH) (Nilaparvata lugens, Sogatella furcifera, and Laodelphax striatellus) infestation is considered one of the most serious disasters in rice production in Asia. In order to use visible images to detect stress in rice production caused by RPH infestation, an algorit...
  6. A new Oligocene Calocedrus from South China and its implications for transpacific floristic exchanges.

    American Journal of Botany 99(1):108 (2012) PMID 22223689

    Calocedrus is among the genera with a typical eastern Asian-western North American disjunct distribution today. The origin of its modern distribution pattern can be better understood by examining its fossil record. The present article reports for the first time a new fossil species of this genus...

    The present paper reports a new species of Cupressus based on compressed material from the Oligocene Ningming Formation of the Ningming County, Guangxi Zhuang Autonomous Region, South China. The foliage shoots described as Cupressus guangxiensis sp. nov. are almost identical w...
  8. A new Tertiary Ginkgo (Ginkgoaceae) from the Wuyun Formation of Jiayin, Heilongjiang, northeastern China and its paleoenvironmental implications.

    American Journal of Botany 97(3):446 (2010) PMID 21622408

    The living fossil Ginkgo, a relict of a once dominant gymnosperm, existed and flourished early in the Mesozoic, but only a vague outline of its evolutionary history in the Tertiary has been unveiled. Here we describe a new species, Ginkgo jiayinensis sp. nov., from the Wuyun Formation of Jiayin,...
  9. Morphology and age ofYimaia(Ginkgoales) from Daohugou Village, Ningcheng, Inner Mongolia, China
