Componentwise Complementary Cycles in Multipartite Tournaments
《Acta Mathematicae Applicatae Sinica》2012年第1期201-208,共8页Zhi-hong HE Guo-jun LI Xue-qin ZHOU 
Supported by the National Natural Science Foundation of China (No. 10801114);the Nature Science Foundation of Shandong Province, China (No. ZR2011AL019; No. ZR2011AM005)
The problem of complementary cycles in tournaments and bipartite tournaments was completely solved. However, the problem of complementary cycles in semicomplete n-partite digraphs with n 〉 3 is still open. Based on t...

On Sectional Cycles in Translation Quivers
《Journal of Mathematical Research and Exposition》2003年第3期422-426,共5页姚海楼 平艳茹 
Supported by Fund of Educational Ministry of China and the Fund of Education Committee of Beijing.
In this paper, we prove that there exists no sectional cycle in a translation quiver under certain conditions. So, we generalize Dautista and Smalφ's corresponding result on AR-quiver of an artin algebra.

Cracking in an expansive soil under freeze–thaw cycles被引量：4
《Research in Cold and Arid Regions》2017年第4期392-397,共6页Yang Lu SiHong Liu 
supported by "the Fundamental Research Funds for the Central Universities" (Grant No. 2015B25014);"the Practical Innovation Program for Postgraduate Students of Jiangsu Province, China" (Grant No. SJZZ15_0058);funded by the Priority Academic Program Development of Jiangsu Higher Education Institutions (PAPD) (Grant No. 3014–SYS1401);the organizing committee of "XI International Symposium on Permafrost Engineering (Magadan, Russia, Sept. 5-8, 2017)" for giving the opportunity to exchange this study
Expansive soils located in cold regions can easily endure the action of frost heaving and cyclic freezing–thawing. Cracking can also occur in expansive clayey soils under freeze–thaw cycles, of which little attentio...

List Vertex-arboricity of Planar Graphs without Intersecting 5-cycles被引量：1
《Acta Mathematicae Applicatae Sinica》2020年第2期439-447,共9页Wei-fan WANG Li HUANG Min CHEN 
supported by the National Natural Science Foundation of China(Nos.11971437,11771402);the Natural Science Foundation of Zhejiang Province(No.LY19A010015).
The vertex-arboricity a(G)of a graph G is the minimum number of colors required for a vertex coloring of G such that no cycle is monochromatic.The list vertex-arboricity al(G)is the list-coloring version of this conce...

Is a higher correlation necessary for a more accurate prediction?被引量：1
《Science China(Physics,Mechanics & Astronomy)》2011年第1期172-175,共4页DU ZhanLe WANG HuaNing 
supported by the Chinese Academy of Sciences (Grant No.KGCX3-SYW-403-10);the National Natural Science Foundation of China (Grant Nos.10973020,10673017 and 40890161)
A higher correlation tends to yield a more accurate prediction,so that a correlation as high as possible has been searched for and employed in the prediction of solar activity.Instead of using geomagnetic activity dur...
