| 1 | Stochastic processes in renewable power systems: From frequency domain to time domain显示文摘With the increasing penetration of renewable energy resources(RESs), the uncertainties of volatile renewable generations significantly affect the power system operation. Such uncertainties are usually modeled as stochastic variables obeying specific distributions by neglecting the temporal correlations. Conventional approaches to hedge the negative effects caused by such uncertainties are thus hard to pursue a trade-off between computation efficiency and optimality. As an alternative, the theory of stochastic process can naturally model temporal correlation in closed forms. Attracted by this feature, our research group has been conducting thorough researches in the past decade to introduce stochastic processes within renewable power systems. This paper summarizes our works from the perspective of both the frequency domain and the time domain, provides the tools for the analysis and control of power systems under a unified framework of stochastic processes, and discusses the underlying reasons that stochastic process-based approaches can perform better than conventional approaches on both computational efficiency and optimality. These work may shed a new light on the research of analysis, control and operation of renewable power systems.Finally, this paper outlooks the theoretic developments of stochastic processes in future’s renewable power systems. | SONG YongHua CHEN XiaoShuang LIN Jin LIU Feng QIU YiWei | 2019 | Science China(Technological Sciences)2019，62，12： | 4 |
| 2 | Risk prediction models for lung cancer:Perspectives and dissemination显示文摘Objective: The objective was to systematically assess lung cancer risk prediction models by critical evaluation of methodology, transparency and validation in order to provide a direction for future model development.Methods: Electronic searches(including PubMed, EMbase, the Cochrane Library, Web of Science, the China National Knowledge Infrastructure, Wanfang, the Chinese BioMedical Literature Database, and other official cancer websites) were completed with English and Chinese databases until April 30 th, 2018. Main reported sources were input data, assumptions and sensitivity analysis. Model validation was based on statements in the publications regarding internal validation, external validation and/or cross-validation.Results: Twenty-two studies(containing 11 multiple-use and 11 single-use models) were included. Original models were developed between 2003 and 2016. Most of these were from the United States. Multivariate logistic regression was widely used to identify a model. The minimum area under the curve for each model was 0.57 and the largest was 0.87. The smallest C statistic was 0.59 and the largest 0.85. Six studies were validated by external validation and three were cross-validated. In total, 2 models had a high risk of bias, 6 models reported the most used variables were age and smoking duration, and 5 models included family history of lung cancer.Conclusions: The prediction accuracy of the models was high overall, indicating that it is feasible to use models for high-risk population prediction. However, the process of model development and reporting is not optimal with a high risk of bias. This risk affects prediction accuracy, influencing the promotion and further development of the model. In view of this, model developers need to be more attentive to bias risk control and validity verification in the development of models. | Wei Tang Qin Peng Yanzhang Lyu Xiaoshuang Feng Xin Li Luopei Wei Ni Li Hongda Chen Wanqing Chen Min Dai Ning Wu Jiang Li Yao Huang | 2019 | Chinese Journal of Cancer Research2019，31，2： | 2 |
| 3 | Dissipative Particle Dynamics Simulation on Bonding Reaction Between Surface Modified Nanoparticles显示文摘A simulation study was carried out by using dissipative particle dynamics(DPD) method to explore the effects of properties of coating chains, such as length, density, rigidity of polymer chains, as well as the distance between nanoparticles on bonding reaction of coating chains grafted onto nanoparticles. The results show that bonding ratios of coated chains strongly depend on the length and density of coating chains. For nanoparticles with different coating densities, the optimum chain length for bonding reaction are varied. The rigidity of coating chains exhibits vigorous effects on bonding reaction that highly depends on chain lengths. DPD simulation can be used to study the bonding reaction between coated nanoparticles, which may help experimental synthesis of nanocomposites with excellent properties. | 唐伟 陈鹏 FENG Xiaoshuang XIA Ru QIAN Jiasheng CAO Ming SU Lifen MIAO Jibin | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，1： | 1 |

| 6 | Rheological and physicomechanical properties of rod milling sand-based cemented paste backfill modified by sulfonated naphthalene formaldehyde condensate显示文摘Rod milling sand(RMS)—a coarse sand aggregate—was recycled for cemented paste backfill(CPB)for the underground mined area at the Jinchuan nickel deposit,named rod milling sand-based cemented paste backfill(RCPB).The adverse effects of coarse particles on the transportation of CPB slurry through pipelines to underground stopes resulting in weakening of the stability of the backfill system are well known.Therefore,sulfonated naphthalene formaldehyde(SNF)condensate was used for the performance improvement of RCPB.The synergistic effect of solid content(SC),lime-to-sand ratio,and SNF dosage on the rheological and physicomechanical properties,including slump,yield stress,bleeding rate,uniaxial compressive strength(UCS),as well as mechanism analysis of RCPB,have been explored.The results indicate that the effect of SNF on RCPB performance is related to the SNF dosage,lime-to-sand ratio,and SC.The slump of fresh RCPB with 0.1wt%-0.5wt%SNF increased by 2.6%-26.2%,whereas the yield stress reduced by 4.1%-50.3%,indicating better workability and improved cohesiveness of the mix.The bleeding rate of fresh RCPB decreased first and then rose with the increase of SNF dosage,and the peak decrease was 67.67%.UCS of RCPB first increased and then decreased with the increase of SNF dosage.At the optimal SNF addition ratio of 0.3wt%,the UCS of RCPB curing for 7,14 and,28 d ages increased by 31.5%,28.4%,and 29.5%,respectively.The beneficial effects of SNF in enhancing the early UCS of RCPB have been corroborated.However,the later UCS increases at a slower rate.The research findings may guide the design and preparation of RCPB with adequate performance for practical applications. | Qinli Zhang Hao Wu Yan Feng Daolin Wang Huaibin Su Xiaoshuang Li | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，2： | 0 |
| 7 | Synthesis and Immobilization of Polystyrene-b-Polyvinyltriethoxysilane Micelles显示文摘Diblock copolymers polystyrene-block-polyvinyltriethoxysilane(PS-b-PVTES) were synthesized via atom transfer radical polymerization(ATRP), which self-assembled into spherical micelles in solvent of THF-methanol mixtures. The self-assembled micelles were immobilized by cross-linking reaction of VTES in a shell layer of micelles. The chemical structures of block copolymers and morphology of micelles were characterized in detail. It was found that the size of immobilized micelles was strongly affected by the copolymer concentration, composition of mixture solvent, and block ratios. | 朱赛赛 ZHU Hui 夏茹 FENG Xiaoshuang CHEN Peng QIAN Jiasheng CAO Ming YANG Bin MIAO Jibin SU Lifen SONG Changjiang | 2018 | Journal of Wuhan University of Technology(Materials Science)2018，33，1： | 0 |
| 8 | Fine Tuning of the Electronic Properties of Novel BTPE Using Oligosilanyl Linkages and Their Application in Rapid High-Resolution Visualization of Latent Fingerprints显示文摘Structural modifications throughπ-interactions usually result in redshifts in luminescence and,as a consequence,the loss of the natural color of the chromophore.Besides,employing Si-Siσ-bridging to manipulate the electronic properties of organic materials has remained largely unexplored.Herein,we report a series of novel bis-tetraphenylethenes(BTPEs)with oligosilanyl linkages,termed BTPE-Sin molecules,used to manipulate the photophysical properties of luminogens subtly throughσ–πconjugation.These oligosilanyl-bridged molecules were thermally,highly stable,and exhibited enhanced aggregation-induced emissions,as well as luminescence efficiencies while retaining most of their original color.Our current BTPEs fabrications have easy-to-operate,fast,and high-resolution identification properties toward LFPs.Also,they are highly specific to individuals,and hence,vital in forensic investigations.We achieved these features through the introduction of oligosilanyl chains that increased the lipophilicity of the significantly.This work offers a universal and straightforward approach for the generation of highly emissive organic materials and enables fine-tuning of their electronic properties for multifunctional applications. | Xiaoshuang Xiang Zhikuan Zhou Hongjie Feng Siyang Feng Lizhi Gai Hua Lu Zijian Guo | 2020 | CCS Chemistry2020，2，3： | 0 |
