| 1 | 基于小波分解和布谷鸟搜索算法的小波神经网络风速预测(英文)显示文摘风速预测是风电场运行和风电并网过程中的关键技术之一。由于风速序列呈现出明显的间歇性和波动性,使用单一模型进行时预测难以取得满意的结果。本文发展了三种混合多步预测模型,并将他们与已有的风速预测模型相比较。这三个模型结合了小波分解、布谷鸟搜索算法和小波神经网络,分别记为CS-WD-ANN,CS-WNN和CS-WD-WNN。研究采用中国山东省两个风电场的实测数据进行模拟试验和模型比较,结果显示CS-WD-WNN表现最佳,具有最低的统计误差。 | ZHANG Ye YANG Shiping GUO Zhenhai GUO Yanling ZHAO Jing | 2019 | Atmospheric and Oceanic Science Letters2019，12，2： | 5 |
| 2 | Regularization method with two parameters for nonlinear ill-posed problems显示文摘This paper is devoted to the regularization of a class of nonlinear ill-posed problems in Banach spaces. The operators involved are multi-valued and the data are assumed to be known approximately. Under the assumption that the original problem is solvable, a strongly convergent approximation procedure is designed by means of the Tikhonov regularization method with two pa- rameters. | LIU ZhenHai LI Jing LI ZhaoWen | 2008 | Science China Mathematics2008，51，1： | 4 |
| 3 | Mechanical activation of spike fosters SARS-CoV-2 viral infection显示文摘The outbreak of SARS-CoV-2(SARS2)has caused a global COVID-19 pandemic.The spike protein of SARS2(SARS2-S)recognizes host receptors,including ACE2,to initiate viral entry in a complex biomechanical environment.Here,we reveal that tensile force,generated by bending of the host cell membrane,strengthens spike recognition of ACE2 and accelerates the detachment of spike’s S1 subunit from the S2 subunit to rapidly prime the viral fusion machinery.Mechanistically,such mechano-activation is fulfilled by force-induced opening and rotation of spike’s receptor-binding domain to prolong the bond lifetime of spike/ACE2 binding,up to 4 times longer than that of SARS-S binding with ACE2 under 10 pN force application,and subsequently by force-accelerated S1/S2 detachment which is up to~103 times faster than that in the no-force condition.Interestingly,the SARS2-S D614G mutant,a more infectious variant,shows 3-time stronger force-dependent ACE2 binding and 35-time faster force-induced S1/S2 detachment.We also reveal that an anti-S1/S2 non-RBD-blocking antibody that was derived from convalescent COVID-19 patients with potent neutralizing capability can reduce S1/S2 detachment by 3×106 times under force.Our study sheds light on the mechano-chemistry of spike activation and on developing a non-RBD-blocking but S1/S2-locking therapeutic strategy to prevent SARS2 invasion. | Wei Hu Yong Zhang Panyu Fei Tongtong Zhang Danmei Yao Yufei Gao Jia Liu Hui Chen Qiao Lu Tenny Mudianto Xinrui Zhang Chuxuan Xiao Yang Ye Qiming Sun Jing Zhang Qi Xie Pei-Hui Wang Jun Wang Zhenhai Li Jizhong Lou Wei Chen | 2021 | Cell Research2021，31，10： | 2 |
| 4 | Price-based interference avoidance game in the Gaussian interference channel显示文摘This paper considers a distributed interference avoidance problem employing frequency assignment in the Gaussian interference channel(IC).We divide the common channel into several sub-channels and each user chooses one sub-channel for transmission in such a way that the total interference in the IC is minimum.This mechanism named interference avoidance in this paper can be modeled as a competitive game model.And a completely autonomous distributed iterative algorithm called distributed interference avoidance algorithm(DIA)is adopted to achieve the Nash equilibrium(NE)of the game.Due to the self-optimum,the DIA is a sub-optimal algorithm.Therefore,through introducing an optimal compensation(or price)into the competitive game model,we successfully develop a compensation-based game model to approximate the optimal interference avoidance problem.Moreover,an optimal algorithm called iterative optimal interference avoidance algorithm(IOIA)is proposed to reach the optimality of the interference avoidance scheme.We analyze the implementation complexity of the proposed algorithm which is only O(N),with N standing for the number of users in the IC.We also give the proof on the convergence of the proposed algorithm.The performance upper bound and lower bound are derived for the IOIA algorithm.The simulation results show that the IOIA does reach the optimality under the condition of interference avoidance mechanism. | JING ZhenHai BAI BaoMing MA Xiao | 2012 | Science China(Information Sciences)2012，55，2： | 1 |

| 7 | The process and mechanism for cesium and rubidium extraction with saponified 4-tert-butyl-2-(a-methylbenzyl) phenol显示文摘Cesium(Cs)and rubidium(Rb)separation from brine is an important and application-oriented topic.4-tert-butyl-2-(a-methylbenzyl)phenol(t-BAMBP)has been used for Cs and Rb extraction.However,the traditional extraction technology is base and acid consumed.In the present work,an innovative process for Cs and Rb extraction with t-BAMBP is developed,which consists of saponification,extraction,scrubbing and stripping.Both infrared spectrum and electrostatic potential analysis indicate the hydrogen of phenolic hydroxyl is dissociated from t-BAMBP during saponification and the oxygen of phenolic hydroxyl is the binding site for alkali metal ions.Saponified organic phase shows an excellent extraction effect for Cs^(+)and Rb^(+).The extraction reaches equilibrium in 5 min,with 99.5%Cs^(+)and 46.7%Rb^(+)are loaded into the organic phase in the single-stage extraction.Slope method indicates the structure of the extraction complex is MOR·3ROH(M=Cs^(+),Rb^(+),K^(+)),where the electrostatic attraction between M^(+)and the oxygen of phenolic hydroxyl is dominant,and the cation–p interaction has a significant effect also.The extraction complex of MOR·3ROH dissociates in the acid environment while scrubbing and stripping is completed.The Cs^(+)and Rb^(+)are separated from the mixture phase,the proton H bonds to the phenolic hydroxyl group,and the extractant is regenerated. | Dengke Pang Zhihong Zhang Yongquan Zhou Zhenhai Fu Quan Li Yongming Zhang Guangguo Wang Zhuanfang Jing | 2022 | Chinese Journal of Chemical Engineering2022，35，6： | 1 |

| 9 | The Biological Significance of Multi-copy Regions and Their Impact on Variant Discovery显示文摘Identification of genetic variants via high-throughput sequencing(HTS)technologies has been essential for both fundamental and clinical studies.However,to what extent the genome sequence composition affects variant calling remains unclear.In this study,we identified 63,897 multi-copy sequences(MCSs)with a minimum length of 300 bp,each of which occurs at least twice in the human genome.The 151,749 genomic loci(multi-copy regions,or MCRs)harboring these MCSs account for 1.98% of the genome and are distributed unevenly across chromosomes.MCRs containing the same MCS tend to be located on the same chromosome.Gene Ontology(GO)analyses revealed that 3800 genes whose UTRs or exons overlap with MCRs are enriched for Golgirelated cellular component terms and various enzymatic activities in the GO biological function category.MCRs are also enriched for loci that are sensitive to neocarzinostatin-induced double-strand breaks.Moreover,genetic variants discovered by genome-wide association studies and recorded in dbSNP are significantly underrepresented in MCRs.Using simulated HTS datasets,we show that false variant discovery rates are significantly higher in MCRs than in other genomic regions.These results suggest that extra caution must be taken when identifying genetic variants in the MCRs via HTS technologies. | Jing Sun Yanfang Zhang Minhui Wang Qian Guan Xiujia Yang Jin Xia Ou Mingchen Yan Chengrui Wang Yan Zhang Zhi-Hao Li Chunhong Lan Chen Mao Hong-Wei Zhou Bingtao Hao Zhenhai Zhang | 2020 | Genomics, Proteomics & Bioinformatics2020，18，5： | 0 |
