| 2 | Application of a catch-based method for stock assessment of three important fisheries in the East China Sea显示文摘Most fisheries in China do not have maximum sustainable yield(MSY) estimates due to limited and poor data.Therefore, finding a common method to estimate MSY or total allowable catch(TAC) for fishery management is necessary. MSYs of three important fisheries in the East China Sea were evaluated through a catch-based model.Estimates for intrinsic rate of increase(r) and five levels of process error were considered. Results showed hairtail Trichiurus japonicas(Temminck and Schlegel) and small yellow croaker Larimichthys polyactis(Bleeker) fisheries experienced overfishing from the mid-1990 s to the early 2000 s, and the suggested TACs were 55.8×10~4 t and9.06×10~4 t, respectively. Decades of overfishing in wintering and spawning grounds of large yellow croaker Larimichthys crocea(Richardson) caused the fishery's collapse in the 1980 s, and it has not recovered until today.The Catch–MSY model generated similar estimated MSYs with other methods and may be a useful choice for the assessment of regional stocks in China. | ZHANG Kui ZHANG Jun XU Youwei SUN Mingshuai CHEN Zuozhi YUAN Meng | 2018 | Acta Oceanologica Sinica2018，37，2： | 14 |
| 3 | Strengths, weaknesses, opportunities and threats (SWOT) analysis of reinitiation into methamphetamine abusers: qualitative findings from an exploration of methamphetamine abusers in Shanghai, China显示文摘Background Despite high relapse rate among methamphetamine (MA) abusers, there still have been little empirical data to date detecting the risk factors related to craving and relapse from the perspective of MA abusers. Therefore, the aim of this study was to use qualitative research methods exploring the strengths, weaknesses, opportunities and threat factors that could facilitate or impede individuals' abstinence in a real-life context from the perspectives of MA abusers. Aim To use qualitative research methods exploring the strengths, weaknesses, opportunities and threat factors relating to individuals' abstinence in a real-life context. Method Semistructured interviews were conducted with 32 MA abusers recruited in Shanghai guided by open-ended questions on narrating the real-life catalysts and inhibitors related to craving, initiation, relapse and abstinence. All data were transcribed verbatim and analysed using a strengths, weaknesses, opportunities and threats (SWOT) analysis. Results The results of the SWOT analysis revealed that contextual factors including peer influence, prevalence and availability of MA, familiar venue of MA use, discrimination, sexual behaviours, alcohol, emotional states and their attitudes towards smoking MA were important factors that contribute to reinitiation and relapse. Surveillance systems, antidrug social workers, vocational skills trainings, moving to another city and family responsibility might serve as counter measures targeti叩 those mentioned weaknesses and threats above. Conclusion This SWOT analysis highlights the complex nature of relapse. Comprehensive interventions strengtheni叩 coping skills such as virtual reality techniques are desperately needed to facilitate individuals1 sustained abstinence. | Youwei Zhu Na Zhong Hang Su Xiaolu Ruan Jiayi Bao Lei Zhang Jiang Du Ding Xu Rongjie Ding Ke Xiao Min Zhao | 2019 | General Psychiatry2019，32，3： | 9 |

| 5 | Genome-wide Analysis of MYB Gene Family in Potato Provides Insights into Tissue-specific Regulation of Anthocyanin Biosynthesis显示文摘The MYB transcription factor is one of the largest gene families in plants,playing an important role in regulating plant growth,development,response to stress,senescence,and especially the anthocyanin biosynthesis.In this study,A total of 217 MYB genes,including 901R-MYBs,124 R2R3-MYBs,and 3 R1R2R3-MYBs have been identified from the potato genome.The 1R-MYB and R2R3-MYB family members could be divided into 20 and 35 subgroups respectively.Analysis of gene structure and protein motifs revealed that members within the same subgroup presented similar exon/intron and motif organization,further supporting the results of phylogenetic analysis.Potato is an ideal plant to reveal the tissue-specific anthocyanins biosynthesis regulated by MYB,as the anthocyanins could be accumulated in different tissues,showing colorful phenotypes.Five pairs of colored and colorless tissues,stigma,petal,stem,leaf,and tuber flesh,were applied to the transcriptomic analysis.A total of 70 MYB genes were found to be differentially expressed between colored and colorless tissues,and these differentially expressed genes were suspected to regulate the biosynthesis of anthocyanin of different tissues.Co-expression analysis identified numerous potential interactive regulators of anthocyanins biosynthesis,involving 39 MYBs,24 bHLHs,2 WD-repeats,and 29 biosynthesis genes.Genome-wide association study(GWAS)of tuber flesh color revealed amajor signal at the end of Chromosome 10,which was co-localized with reported I gene(StMYB88),controlling tuber peel color.Analyses of DEGs(Differentially Expression Genes)revealed that both StMYB88 and StMYB89 were closely related to regulating anthocyanin biosynthesis of tuber flesh.This work offers a comprehensive overview of the MYB family in potato and will lay a foundation for the functional validation of these genes in the tissue-specific regulation of anthocyanin biosynthesis. | Yumei Li Jun Liang Xiangzhi Zeng Han Guo Youwei Luo Philip Kear Shouming Zhang Guangtao Zhu | 2021 | Horticultural Plant Journal2021，7，2： | 8 |
| 6 | Adsorption-energy-based activity descriptors for electrocatalysts in energy storage applications显示文摘Energy storage technologies, such as fuel cells, ammonia production and lithium–air batteries, are important strategies for addressing the global challenge of energy crisis and environmental pollution.Taking overpotential as a direct criterion, we illustrate in theory and experiment that the adsorption energies of charged species such as Li^++e^-and H^++e^-are a central parameter to describe catalytic activities related to electricity-in/electricity-out efficiencies. The essence of catalytic activity is revealed to relate with electronic coupling between catalysts and charged species. Based on adsorption energy, some activity descriptors such as d-band center, e_g-electron number and charge-transfer capacity are further defined by electronic properties of catalysts that directly affect interaction between catalysts and charged species. The present review is helpful for understanding the catalytic mechanisms of these electrocatalytic reactions and developing accurate catalytic descriptors, which can be employed to screen high-activity catalysts in future high-throughput calculations and experiments. | Youwei Wang Wujie Qiu Erhong Song Feng Gu Zhihui Zheng Xiaolin Zhao Yingqin Zhao Jianjun Liu Wenqing Zhang | 2018 | National Science Review2018，5，3： | 8 |
| 7 | Preparation of V-doped TiO_2 Photocatalysts by the Solution Combustion Method and Their Visible Light Photocatalysis Activities显示文摘A series of nanocrystalline V-doped(0.0-3.0 at.%) TiO2 catalysts have been successfully prepared by the one-step solution combustion method using urea as a fuel. The obtained powders were characterized by XRD, SEM, Raman, XPS and UV-Vis DRS. The effects of V doping concentration on the phase structure and photocatalytic properties were investigated. XRD, Raman, and XPS show that V doping diffuses into TiO2 crystal lattice mainly in the form of V5+ and causes a phase transition from anatase to rutile. V doping can widen the light absorption range of TiO2, with the absorption threshold wavelength shifting from 425 to 625 nm. The photocatalytic activity of V-doped TiO2 powders were evaluated by the photocatalytic degradation of methyl orange(MO) under visible light irradiation. It is found that V doping enhances the photocatalytic activity under visible light irradiation and the optimal degradation rate of MO is about 95.8% with 1.0 at% V-doped TiO2. | 马晓 薛丽红 YIN Shengming YANG Miao YAN Youwei | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，5： | 6 |
| 8 | Structural and biochemical mechanism for increased infectivity and immune evasion of Omicron BA.2 variant compared to BA.1 and their possible mouse origins显示文摘The Omicron BA.2 variant has become a dominant infective strain worldwide.Receptor binding studies show that the Omicron BA.2 spike trimer exhibits 11-fold and 2-fold higher potency in binding to human ACE2 than the spike trimer from the wildtype(WT)and Omicron BA.1 strains.The structure of the BA.2 spike trimer complexed with human ACE2 reveals that all three receptor-binding domains(RBDs)in the spike trimer are in open conformation,ready for ACE2 binding,thus providing a basis for the increased infectivity of the BA.2 strain.JMB2002,a therapeutic antibody that was shown to efficiently inhibit Omicron BA.1,also shows potent neutralization activities against Omicron BA.2.In addition,both BA.1 and BA.2 spike trimers are able to bind to mouse ACE2 with high potency.In contrast,the WT spike trimer binds well to cat ACE2 but not to mouse ACE2.The structures of both BA.1 and BA.2 spike trimer bound to mouse ACE2 reveal the basis for their high affinity interactions.Together,these results suggest a possible evolution pathway for Omicron BA.1 and BA.2 variants via a human-cat-mouse-human circle,which could have important implications in establishing an effective strategy for combating SARS-CoV-2 viral infections. | Youwei Xu Canrong Wu Xiaodan Cao Chunyin Gu Heng Liu Meriting Jiang Xiaoxi Wang Qingning Yuan Kai Wu Jia Liu Deyi Wang Xianqing He Xueping Wang Su-Jun Deng H.Eric Xu Wanchao Yin | 2022 | Cell Research2022，32，7： | 6 |
| 9 | Aerosol light absorption in a coastal city in Southeast China:Temporal variations and implications for brown carbon显示文摘Light-absorbing carbonaceous aerosols including black carbon(BC) and brown carbon(BrC)play significant roles in atmospheric radiative properties. One-year measurements of aerosol light absorption at multi-wavelength were continuously conducted in Xiamen,southeast of China in 2014 to determine the light absorption properties including absorption coefficients(σabs) and absorption ?ngstr?m exponent(AAE) in the coastal city.Light absorptions of BC and BrC with their contributions to total light absorption were further quantified. Mean σabsat 370 nm and 880 nm were 56.6 ± 34.3 and 16.5 ± 11.2 Mm-1,respectively. σabspresented a double-peaks diurnal pattern with the maximum in the morning and the minimum in the afternoon. σabswas low in warm seasons and high in cold seasons. AAE ranged from 0.26 to 2.58 with the annual mean of 1.46, implying that both fossil fuel combustion and biomass burning influenced aerosol optical properties. σabsof BrC at 370 nm was 24.0 ± 5.7 Mm-1, contributing 42% to the total absorption. The highest AAE(1.52 ± 0.02) and largest BrC contributions(47% ± 4%) in winter suggested the significant influence of biomass burning on aerosol light absorption. Long-distance air masses passing through North China Plain and the Yangtze River Delta led to high AAE and BrC contributions. High AAE value of 1.46 in July indicated that long-range transport of the air pollutants from intense biomass burning in Southeast Asia would affect aerosol light absorption in Southeast China. The study will improve the understanding of light absorption properties of aerosols and the optical impacts of BrC in China. | Yuqing Qiu Xin Wu Yanru Zhang Lingling Xu Youwei Hong Jinsheng Chen Xiaoqiu Chen Junjun Deng | 2019 | Journal of Environmental Sciences2019，31，6： | 5 |
| 10 | Primal-dual algorithms for total variation based image restoration under Poisson noise Dedicated to Professor Lin Qun on the Occasion of his 80th Birthday显示文摘We consider the problem of restoring images corrupted by Poisson noise. Under the framework of maximum a posteriori estimator, the problem can be converted into a minimization problem where the objective function is composed of a Kullback-Leibler(KL)-divergence term for the Poisson noise and a total variation(TV) regularization term. Due to the logarithm function in the KL-divergence term, the non-differentiability of TV term and the positivity constraint on the images, it is not easy to design stable and efficiency algorithm for the problem. Recently, many researchers proposed to solve the problem by alternating direction method of multipliers(ADMM). Since the approach introduces some auxiliary variables and requires the solution of some linear systems, the iterative procedure can be complicated. Here we formulate the problem as two new constrained minimax problems and solve them by Chambolle-Pock's first order primal-dual approach. The convergence of our approach is guaranteed by their theory. Comparing with ADMM approaches, our approach requires about half of the auxiliary variables and is matrix-inversion free. Numerical results show that our proposed algorithms are efficient and outperform the ADMM approach. | WEN YouWei CHAN Raymond Honfu ZENG TieYong | 2016 | Science China Mathematics2016，59，1： | 5 |
| 11 | Zircon U-Pb Ages and Sr-Nd-Hf Isotopic Characteristics of the Huichizi Granitic Complex in the North Qinling Orogenic Belt and Their Geological Significance显示文摘The Huichizi granite complex is the largest Paleozoic I-type intrusion located in the North Qinling orogenic belt(NQB). In this study, we present systematic geochemical element data, zircon U-Pb ages, Lu-Hf isotopic data, and Sr-Nd isotopic data for the Huichizi granites. In terms of mineral and chemical compositions, these granites are biotite monzonitic and alkali-feldspar granites, both of which are characterized by high SiO 2 and total alkali contents and low Mg O, Ti O2, and TFeO contents. These granites are weakly peraluminous(A/CNK values are 1–1.06 for biotite monzonitic granites and 1.04–1.09 for alkali-feldspar granites) and possess the geochemical characteristics of adakitic rocks, e.g., high Sr contents(319 ppm–633 ppm), Sr/Y ratios(18.5–174), and(La/Yb)N ratios(17.6–57) and low MgO(0.04 wt.%–0.83 wt.%), Y(3.0 ppm–17.2 ppm), and heavy rare-earth element(HREE) contents. This indicates that these rocks were most likely derived from the partial melting of a thickened lower crust. In situ zircon U-Pb dating of these granites yields Early Caledonian ages(437 Ma for biotite monzonitic granites and 424 Ma for alkali-feldspar granites), indicating that the Huichizi granitic complex is the product of multi-periodic magmatism. The positive but varying zircon εHf(t) values(+0.6 to +8.5) suggest that this thickened lower crust was mainly juvenile, i.e., accreted from depleted mantle during the Neo-Mesoproterozoic Period, but involved the ancient recycled crust. Biotite monzonitic granites formed during crust thickening at the extrusion stage, whereas the alkali granites formed during crust thickening at the extension stage(post extrusion). The Huichizi granite complex witnessed the process of extrusion to extension because of the collision between the NCB and the Qinling microcontinent in the Caledonian. | Youwei Chen Ruizhong Hu Xianwu Bi Shaohua Dong Yue Xu Ting Zhou | 2018 | Journal of Earth Science2018，29，3： | 5 |

| 13 | Experimental and numerical investigations of scale-up effects on the hydrodynamics of slurry bubble columns显示文摘Experiments and simulations were conducted for bubble columns with diameter of 0.2 m(180 mm i.d.), 0.5 m(476 mm i.d.) and 0.8 m(760 mm i.d.) at high superficial gas velocities(0.12–0.62 m·s-1) and high solid concentrations(0–30 vol%). Radial profiles of time-averaged gas holdup, axial liquid velocity, and turbulent kinetic energy were measured by using in-house developed conductivity probes and Pavlov tubes. Effects of column diameter, superficial gas velocity, and solid concentration were investigated in a wide range of operating conditions. Experimental results indicated that the average gas holdup remarkably increases with superficial gas velocity, and the radial profiles of investigated flow properties become steeper at high superficial gas velocities. The axial liquid velocities significantly increase with the growth of the column size, whereas the gas holdup was slightly affected. The presence of solid in bubble columns would inhibit the breakage of bubbles, which results in an increase in bubble rise velocity and a decrease in gas holdup, but time-averaged axial liquid velocities remain almost the same as that of the hollow column. Furthermore, a 2-D axisymmetric k–ε model was used to simulate heterogeneous bubbly flow using commercial code FLUENT 6.2. The lateral lift force and the turbulent diffusion force were introduced for the determination of gas holdup profiles and the effects of solid concentration were considered as the variation of average bubble diameter in the model. Results predicted by the CFD simulation showed good agreement with experimental data. | Zhaoqi Li Xiaoping Guan Lijun Wang Youwei Cheng Xi Li | 2016 | Chinese Journal of Chemical Engineering2016，24，8： | 4 |
| 14 | An Examination of the Predictability of Tropical Cyclone Genesis in High-Resolution Coupled Models with Dynamically Downscaled Coupled Data Assimilation Initialization显示文摘Predicting tropical cyclone(TC)genesis is of great societal importance but scientifically challenging.It requires fineresolution coupled models that properly represent air−sea interactions in the atmospheric responses to local warm sea surface temperatures and feedbacks,with aid from coherent coupled initialization.This study uses three sets of highresolution regional coupled models(RCMs)covering the Asia−Pacific(AP)region initialized with local observations and dynamically downscaled coupled data assimilation to evaluate the predictability of TC genesis in the West Pacific.The APRCMs consist of three sets of high-resolution configurations of the Weather Research and Forecasting−Regional Ocean Model System(WRF-ROMS):27-km WRF with 9-km ROMS,and 9-km WRF with 3-km ROMS.In this study,a 9-km WRF with 9-km ROMS coupled model system is also used in a case test for the predictability of TC genesis.Since the local sea surface temperatures and wind shear conditions that favor TC formation are better resolved,the enhanced-resolution coupled model tends to improve the predictability of TC genesis,which could be further improved by improving planetary boundary layer physics,thus resolving better air−sea and air−land interactions. | Mingkui LI Shaoqing ZHANG Lixin WU Xiaopei LIN Ping CHANG Gohkan DANABASOGLU Zhiqiang WEI Xiaolin YU Huiqin HU Xiaohui MA Weiwei MA Haoran ZHAO Dongning JIA Xin LIU Kai MAO Youwei MA Yingjing JIANG Xue WANG Guangliang LIU Yuhu CHEN | 2020 | Advances in Atmospheric Sciences2020，37，9： | 4 |
| 15 | Electrospun polyporous VN nanofibers for symmetric all-solid-state supercapacitors显示文摘To promote the energy density of symmetric all-solid-state supercapacitors(SCs),efforts have been dedicated to searching for high-performance electrode materials recently. In this paper,vanadium nitride(VN) nanofibers with mesoporous structure have been fabricated by a facile electrospinning method. Their crystal structures and morphology features were characterized by X-ray diffraction,scanning electron microscopy,and transmission electron microscopy. The mesoporous structure of VN nanofibers,which can provide short electrolyte diffusion routes and conducting electron transport pathways,is beneficial to their performance as a supercapacitor electrode. Under a stable electrochemical window of 1.0 V,VN nanofibers possess an excellent mass specific capacitance of 110.8 F/g at a scan rate of 5 mV/s. Moreover,the VN nanofibers were further assembled into symmetric all-solid-state SCs,achieving a high energy density of 0.89 mW·h/cm^3 and a high power density of 0.016 W/cm^3 over an operating potential range from 0 to 1.0 V. These results demonstrate that VN nanofibers could be potentially used for energy storage devices. | Dandan ZHANG Jing LI Zhen SU Sanyuan HU Heping LI Youwei YAN | 2018 | Journal of Advanced Ceramics2018，7，3： | 3 |

| 17 | Effects of Mechanical Alloying Parameters on the Microstructures of Nanocrystalline Cu-5 wt% Cr Alloy显示文摘Nanocrystalline Cu-5 wt%Cr alloy powders were fabricated by mechanical alloying (MA). The effects of MA processing parameters on the crystallite size, solid solubility, and microstructures of the Cu-5 wt%Cr alloys were investigated including type and size distribution of the grinding medium and ball-to-powder weight ratio (BPR). The results show that the crystallites were refined effectively and solid solubility of Cr in Cu was extended when heavier ball and higher BPR were adopted. The maximum solubility is extended up to 5.6 at% (namely 4.6 wt%) Cr in Cu by use of a combination of large and small size WC-Co balls with BPR of 30:1. A Cu-5 wt%Cr supersaturated solid solution alloy bulk is obtained by spark plasma sintering the as-milled powders at 900 ℃ for 5 min. | 史昆玉 薛丽红 YAN Youwei SHEN Tao | 2013 | Journal of Wuhan University of Technology(Materials Science)2013，28，1： | 3 |
| 18 | A Bionic Study on the Anti-erosion Mechanism of Laudakia stoliczkana:Experimental and Numerical Aspects显示文摘The scales of body surface of Laudakia stoliczkana have the morphology of convex hulls,which are arranged in groove structure in macroscopic scale.Its body surface skin is mainly composed of the'soft'layer of keratin and the'hard'layer of the cuticle covering on the'soft'layer.The coupling effect of the scale morphology and skin's structure gives Laudakia stoliczkana the excellent ability to resist the sand erosion in desert environment.Inspired by the convex surface morphology and the composite structure of the'soft'and'hard'layers of the skin of Laudakia stoliczkana^the coupling bionic samples are febricated and the erosion resistance performance is tested.The test results show that the coupling bionic samples have good erosion resistance perfbimance and the samples with spherical convex hull exhibit the best erosion resistance performance.Moreover,based on the theory of stress wave propagation in solid the numerical simula tions of particles impacting to the coupling bionic samples and bionic layered structure are done respectively and the anti-erosion me chanism of the bionic layered structure is analyzed.The simulation results are consistent with the experimental results,which show that the coupling bionic samples can effectively reduce the amplitude of the incident stress wave,and thus can prevent the failure of samples. | Ping Liang Youhong Sun Sihan Liu Tianwei Liang Yuhang Zhang Youwei Wang Luquan Ren | 2019 | Journal of Bionic Engineering2019，16，5： | 2 |

The films showed wurtzite structure and no other phase was found. The chemical state of Ni was found to be bivalent by X-ray photoelectron spectroscopy. The results of magnetic measurements at room temperature indicated that the films were ferromagnetic, and magnetic moment decreased with rise of Ni concentration. The magnetization of Ni (10 mol%)-doped ZnO film annealed in nitrogen was lower than that annealed in argon, suggesting that the density of defects had an effect on ferromagnetism. | YE XiaoJuan SONG HaiAn ZHONG Wei QI XiaoSi XU MeiHua JIN ChangQing YANG ZaiXin AU ChakTong DU YouWei | 2010 | 中国科学:技术科学2010，40，2： | 2 |
