A rough granular computing in discovery of process models from data and domain knowledge

The rapid expansion of the Internet has resulted not only in the ever growing amount of data therein stored, but also in the burgeoning complexity of the concepts and phenomena pertaining to those data. This issue has been vividly compared by the renowned statistician, prof. Friedman of Stanford University, to the advances in human mobility from the period of walking afoot to the era of jet travel. These essential changes in data have brought new challenges to the development of new data mining methods, especially that the treatment of these data increasingly involves complex processes that elude classic modeling paradigms. “Hot” datasets like biomedical, financial or net user behavior data are just a few examples. Mining such temporal or stream data is on the agenda of many research centers and companies worldwide. In the data mining community, there is a rapidly growing interest in developing methods for process mining, e.g〖DK〗., for discovery of structures of temporal processes from data. Works on process mining have recently been undertaken by many renowned centers worldwide. This research is also related to functional data analysis , cognitive networks , and dynamical system modeling, e.g., in biology. In the lecture, we outline an approach to discovery of processes from data and domain knowledge which is based on the roughgranular computing.     

稠油热采井筒注汽优化设计方法

建立了稠油热采中井筒注汽优化模型,并用穷举法进行了求解。对蒸汽吞吐和蒸汽驱井筒注汽两种情况进行了实例计算和分析。结果表明,提高隔热管隔热性能,可以降低综合成本;降低注汽速率将会增加热损失,从而导致综合成本增大;随着隔热管管径的增加,隔热管造价将增加。运用优化设计方法,可以节省大量的初始投资并降低运行成本,有利于节约能源,提高经济效益

Bacterial peptide deformylase inhibitor PMT analogs inhibit cancer cell growth by interacting with human peptide deformylase

Potent inhibitors of human peptide deformylase （HsPDF） were screened using known PMT analog inhibi- tors of bacterial peptide deformylase. Forty-three species of PMT analogs that are non-peptidyl bacterial PDF inhibitors like actinonin were selected using virtual screening GOLD. Ten species out of 43 that could bind to HsPDF were selected and their antitumor activities were tested. Among them, four species （PMT-172, PMT-173, PMT-199, and PMT-201） showed excellent growth inhibition of cancer cell in the MTT assay. HsPDF-PMT binding was confirmed through a 1H-CPMG-T2 filter NMR experiment leading to a significant change in peak intensity for PMT-172 and PMT-199. These results suggest that PMT analogs could possibly interact with HsPDF and be a novel anticancer drug candidate.
