Investigating the topological structure of quenched lattice QCD with overlap fermions using a multi-probing approximation
《Chinese Physics C》2017年第10期37-48,共12页邹优豪 张剑波 熊光仪 陈莹 刘川 刘玉斌 马建平 
Supported by National Natural Science Foundation of China(NSFC)(11335001,11275169,11075167);supported in part by the DFG and the NSFC(11261130311) through funds provided to the Sino-German CRC 110 "Symmetries and the Emergence of Structure in QCD";funded in part by National Basic Research Program of China(973 Program)(2015CB856700)
The topological charge density and topological susceptibility are determined by a multi-probing approximation using overlap fermions in quenched SU（3） gauge theory. Then we investigate the topological structure of t...

Alternative 3D Modeling Approaches Based on Complex Multi-Source Geological Data Interpretation被引量：5
《Transactions of Tianjin University》2014年第1期7-14,共8页李明超 韩彦青 缪正建 高伟 
Supported by the National Natural Science Foundation of China(No.51379006 and No.51009106);the Program for New Century Excellent Talents in University of Ministry of Education of China(No.NCET-12-0404);the National Basic Research Program of China("973"Program,No.2013CB035903)
Due to the complex nature of multi-source geological data, it is difficult to rebuild every geological structure through a single 3D modeling method. The multi-source data interpretation method put forward in this ana...

A general approach to attribute reduction in rough set theory被引量：2
《Science in China(Series F)》2007年第2期188-197,共10页ZHANG WenXiu QIU GuoFang WU WeiZhi 
Major State Basic Research Development Program of China (973 Program) (Grant No. 2002CB312200);the National Natu-ral Science Foundation of China (Grant Nos. 60673096 and 60373078)
The concept of a consistent approximation representation space is introduced. Many types of information systems can be treated and unified as consistent approximation representation spaces. At the same time, under the...
