Publikováno v: Heliyon, Vol 6, Iss 9, Pp e05042- (2020)
Poultry-litter biochar and Azolla as green manure amendments are reported to enhance paddy soil fertility and rice yields. However, whether their co-application in lowland rice paddies has synergistic effects and whether those benefits are accompanie

Fault Detection for Turbine Engine Disk Based on Adaptive Weighted One-Class Support Vector Machine
Autor: Jiusheng Chen, Xingkai Xu, Xiaoyu Zhang
Publikováno v: Journal of Electrical and Computer Engineering, Vol 2020 (2020)
Fault detection for turbine engine components is becoming increasingly important for the efficient running of commercial aircraft. Recently, the support vector machine (SVM) with kernel function is the most popular technique for monitoring nonlinear

Publikováno v: Journal of Wetlands Environmental Management, Vol 6, Iss 2, Pp 60-73 (2018)
Hot water- and water-extracted organic matter was extracted from soil samples collected after a 31-year long-term experiment which aimed to assess the effect of different fertilization strategies (inorganic fertilizers and organic matters) commonly u

Antecedent soil moisture prior to freezing can affect quantity, composition and stability of soil dissolved organic matter during thaw
Autor: Haohao Wu, Xingkai Xu, Weiguo Cheng, Pingqing Fu, Fayun Li
Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-12 (2017)
Abstract There are large amounts of dissolved organic matter (DOM) released into the soil during spring thaw, but its bioavailability and components are still unknown. The quantity, composition and stability of DOM in water extracts of forest soils d

Radial Basis Function Attention for Named Entity Recognition
Autor: Jiusheng Chen, Xingkai Xu, Xiaoyu Zhang
Publikováno v: ACM Transactions on Asian and Low-Resource Language Information Processing. 22:1-18
Attention mechanism is an increasingly important approach in the field of natural language processing (NLP). In the attention-based named entity recognition (NER) model, most attention mechanisms can calculate attention coefficient to express the imp

Effects of Snow Cover on Carbon Dioxide Emissions and Their δ13C Values of Temperate Forest Soils with and without Litter
Autor: Cheng, Xingkai Xu, Haohao Wu, Jin Yue, Shuirong Tang, Weiguo
Publikováno v: Forests; Volume 14; Issue 7; Pages: 1384
The presence of litter and winter snow cover can affect the decomposition of organic matter in forest soils and changes in δ13C values of soil-respired carbon dioxide (CO2). However, limited information is available on the responses of CO2 emissions
