| 8 | Non-fragile guaranteed cost control for uncertain neutral large-scale interconnected systems显示文摘This paper focuses on the problem of non-fragile decentralized guaranteed cost control for uncertain neutral large-scale interconnected systems with time-varying delays in state,control input and interconnections.A novel scheme,viewing the interconnections with time-varying delays as effective information but not disturbances,is developed.Based on Lyapunov stability theory,using various techniques of decomposing and magnifying matrices,a design method of the non-fragile decentralized guaranteed cost controller for unperturbed neutral large-scale interconnected systems is proposed and the guaranteed cost is presented.The further results are derived for the uncertain case from the criterion of unperturbed neutral large-scale interconnected systems.Finally,an illustrative example shows that the results are significantly better than the existing results in the literatures. | Dan Zhao Qingling Zhang Heli Hu Chunyuan Zhao | 2010 | Journal of Systems Engineering and Electronics2010，21，4： | 1 |
| 9 | MEN1 promotes ferroptosis by inhibiting mTOR-SCD1 axis in pancreatic neuroendocrine tumors显示文摘Pancreatic neuroendocrine tumor(pNET)is the second most common malignant tumors of the pancreas.Multiple endocrine neoplasia 1(MEN1)is the most frequently mutated gene in pNETs and MEN1-encoded protein,menin,is a scaffold protein that interacts with transcription factors and chromatin-modifying proteins to regulate various signaling pathways.However,the role of MEN1 in lipid metabolism has not been studied in pNETs.In this study,we perform targeted metabolomics analysis and find that MEN1 promotes the generation and oxidation of polyunsaturated fat acids(PUFAs).Meanwhile lipid peroxidation is a hallmark of ferroptosis,and we confirm that MEN1 promotes ferroptosis by inhibiting the activation of mTOR signaling which is the central hub of metabolism.We show that stearoyl-coA desaturase(SCD1)is the downstream of MEN1-mTOR signaling and oleic acid(OA),a metabolite of SCD1,recues the lipid peroxidation caused by MEN1 overexpression.The negative correlation between MEN1 and SCD1 is further verified in clinical specimens.Furthermore,we find that BON-1 and QGP-1 cells with MEN1 overexpression are more sensitive to everolimus,a widely used drug in pNETs that targets mTOR signaling.In addition,combined use everolimus with ferroptosis inducer,RSL3,possesses a more powerful ability to kill cells,which may provide a new strategy for the comprehensive therapy of pNETs. | Zeng Ye Haidi Chen Shunrong Ji Yuheng Hu Xin Lou Wuhu Zhang Desheng Jing Guixiong Fan Yue Zhang Xuemin Chen Qifeng Zhuo Jie Chen Xiaowu Xu Xianjun Yu Jin Xu Yi Qin Heli Gao | 2022 | Acta Biochimica et Biophysica Sinica2022，54，11： | 0 |
| 10 | Interactive mechanism and friction modelling of transient tribological phenomena in metal forming processes: A review显示文摘The accurate representation of tribological boundary conditions at the tool–workpiece interface is crucial for analysis and optimization of formability,material flow,and surface quality of components during metal forming processes.It has been found that these tribological conditions vary spatially and historically with process parameters and contact conditions.These time-dependent tribological behaviours are also known as transient tribological phenomena,which are widely observed during forming processes and many other manufacturing application scenarios.However,constant friction values are usually assigned to represent complex and dynamic interfacial conditions,which would introduce deviations in the relevant predictions.In this paper,transient tribological phenomena and the contemporary understanding of the interaction between friction and wear are reviewed,and it has been found that these phenomena are induced by the transitions of friction mechanisms and highly dependent on complex loading conditions at the interface.Friction modelling techniques for transient behaviours for metal forming applications are also reviewed.To accurately describe the evolutionary friction values and corresponding wear during forming,the advanced interactive friction modelling has been established for different application scenarios,including lubricated condition,dry sliding condition(metal-on-metal contact),and coated system. | Xiao YANG Heli LIU Lemeng ZHANG Yiran HU Denis J.POLITIS Mohammad M.GHARBI Liliang WANG | 2024 | Friction2024，12，3： | 0 |
| 11 | Efficient caching strategy based on graph coloring for moving users in ultra dense networks显示文摘Caching popular files in small-cell base stations(SBSs) is considered as a promising technique to meet the demand of ever growing mobile data traffic in ultra dense networks(UDNs). Considering the limited cache capacity and dense deployment of SBSs, how to support uninterrupted and successful caching downloading for moving users is still a challenging problem. In this paper, a graph-coloring-based caching(GCC) algorithm in UDN for moving user under limited SBS storage capacities is proposed. Firstly, considering there may be downloading interruption or even failure due to the random moving of users and small coverage of SBSs, graph coloring algorithm(GCA) is employed for grouping the SBS to cache fragments of several files. Then, the problem of how to conduct caching placement on SBSs is formulated aiming to maximize the amount of data downloaded from SBSs. Finally, an efficient heuristic solution is proposed to get an optimal result. Simulation results show that the algorithm performs better than other caching strategies in prior work, in terms of reducing both backhaul traffic and user download delay. | Hu Chengjia Li Xi Ji Hong Zhang Heli | 2019 | The Journal of China Universities of Posts and Telecommunications2019，26，3： | 0 |
