| 1 | Prostate cancer in Asia:A collaborative report显示文摘The incidence of prostate cancer(PCa)within Asian population used to be much lower than in the Western population;however,in recent years the incidence and mortality rate of PCa in some Asian countries have grown rapidly.This collaborative report summarized the latest epidemiology information,risk factors,and racial differences in PCa diagnosis,current status and new trends in surgery management and novel agents for castration-resistant prostate cancer.We believe such information would be helpful in clinical decision making for urologists and oncologists,health-care ministries and medical researchers. | Rui Chen Shancheng Ren 无 Ming Kwong Yiu Ng Chi Fai Wai Sam Cheng Lap Hong Ian Seiji Naito Tadashi Matsuda Elijah Kehinde Ali Kural Jason Yichun Chiu Rainy Umbas Qiang Wei Xiaolei Shi Liqun Zhou Jian Huang Yiran Huang Liping Xie Lulin Ma Changjun Yin Danfeng Xu Kexin Xu Zhangqun Ye Chunxiao Liu Dingwei Ye Xin Gao Qiang Fu Jianquan Hou Jianlin Yuan Dalin He Tiejun Pan Qiang Ding Fengshuo Jin Benkang Shi Gongxian Wang Xiuheng Liu Dongwen Wang Zhoujun Shen Xiangbo Kong Wanhai Xu Yaoliang Deng Haibo Xia Alexa NCohen Xu Gao Chuanliang Xu Yinghao Sun | 2014 | Asian Journal of Urology2014，1，1： | 13 |
| 2 | Memristors with organic-inorganic halide perovskites显示文摘Organic-inorganic halide perovskites(OHPs)have been intensively studied for application in solar cells with high conversion efficiency exceeding 22%.The unique electrical and optical properties of OHPs have led to their use in optoelectronic device applications beyond photovoltaics,such as light-emitting diodes,photodetectors,transistors.New information storage technologies and computing architectures are being researched extensively with the aim of addressing the growing challenge of approaching end of Moore's law and von Neumann bottleneck.As the fourth basic circuit element,memristor is a leading candidate with powerful capabilities in information storage and neuromorphic computing applications.Recently,OHPs have received growing attention as promising materials for memristors.In particular,their mixed ionic-electronic conduction ability paired with light sensitivity provide OHPs with the opportunity to display novel functions such as optical-erase memory,optogenetics-inspired synaptic functions,and lightaccelerated learning capability.This review covers recent advances in OHP-based memristors development including memristive mechanism and analytical models,universal memristive characteristics for memory and neuromorphic computing applications,and novel multi-functionalization.Challenges and future prospects of OHP-based memristors are also discussed. | Xiaoning Zhao Haiyang Xu Zhongqiang Wang Ya Lin Yichun Liu | 2019 | InfoMat2019，1，2： | 10 |
| 3 | Assessing the impacts of human activities and climate variations on grassland productivity by partial least squares structural equation modeling(PLS-SEM)显示文摘The cause-effect associations between geographical phenomena are an important focus in ecological research. Recent studies in structural equation modeling(SEM) demonstrated the potential for analyzing such associations. We applied the variance-based partial least squares SEM(PLS-SEM) and geographically-weighted regression(GWR) modeling to assess the human-climate impact on grassland productivity represented by above-ground biomass(AGB). The human and climate factors and their interaction were taken to explain the AGB variance by a PLS-SEM developed for the grassland ecosystem in Inner Mongolia, China. Results indicated that 65.5% of the AGB variance could be explained by the human and climate factors and their interaction. The case study showed that the human and climate factors imposed a significant and negative impact on the AGB and that their interaction alleviated to some extent the threat from the intensified human-climate pressure. The alleviation may be attributable to vegetation adaptation to high human-climate stresses, to human adaptation to climate conditions or/and to recent vegetation restoration programs in the highly degraded areas. Furthermore, the AGB response to the human and climate factors modeled by GWR exhibited significant spatial variations. This study demonstrated that the combination of PLS-SEM and GWR model is feasible to investigate the cause-effect relation in socio-ecological systems. | SHA Zongyao XIE Yichun TAN Xicheng BAI Yongfei LI Jonathan LIU Xuefeng | 2017 | Journal of Arid Land2017，9，4： | 8 |

| 5 | Progresses in Sustainable Recycling Technology of Spent Lithium-Ion Batteries显示文摘The number of lithium-ion batteries(LIBs)is steadily increasing in order to meet the ever-growing demand for sustainable energy and a high quality of life for humankind.At the same time,the resulting large number of LIB waste certainly poses safety hazards if it is not properly disposed of and will seriously harm the environment due to its inherent toxicity due to the use of toxic substances.Moreover,the consumption of many scarce precious metal resources is behind the mass production of batteries.In the light of severe environmental,resources,safety and recycling problems,recycling spent LIBs have become an essential urgently needed action to achieve sustainable social development.This review therefore critically analyses the value and the need for recycling of spent LIBs from a variety of resources and the environment.A range of existing technologies for recycling and reusing spent LIBs,such as pretreatment,pyrometallurgy,hydrometallurgy,and direct recycled methods,is subsequently summarized exclusively.In addition,the benefits and problems of the methods described above are analyzed in detail.It also introduces recycling progress of other LIB components,such as anodes,separators,and electrolytes,as well as the high-value cathode.Finally,the prospects for recycling LIBs are addressed in four ways(government,users,battery manufacturers,and recyclers).This review should contribute to the development of the recycling of used LIBs,particularly in support of industrialization and recycling processes. | Kaidi Du Edison Huixiang Ang Xinglong Wu Yichun Liu | 2022 | Energy & Environmental Materials2022，5，4： | 7 |
| 6 | Effects of temperature and pressure on the structural and optical properties of ZnO films grown by pulsed laser deposition显示文摘ZnO thin films were deposited on fused silica via pulsed laser deposition (PLD) at substrate temperatures from 300°C to 800°C and ambient oxygen pressures ranging from 10-2 mTorr to 240 mTorr. X-ray diffraction (XRD) and Raman spectra indicated that wurtzite ZnO was obtained in all cases. The highly c-oriented ZnO films were obtained for oxygen pressures above 11 mTorr. The room-temperature photoluminescence (PL) spectra demonstrated that all the films exhibited strong near-band-edge (NBE) emission, while deep-level (DL) emission was also observed in films deposited at oxygen pressures below 80 mTorr. From analysis of the XRD, Raman and photoluminescence PL data, an optimal condition was identified for the deposition of highly crystallized ZnO films. | ZHAO Lei, XU ChangShan, LIU YuXue & LIU YiChun Center for Advanced Opto-Electronic Functional Materials Research, Northeast Normal University, Changchun 130024, China | 2010 | Science China(Technological Sciences)2010，53，2： | 6 |
| 7 | Novel SNPs in IL-17F and IL-17A genes associated with somatic cell count in Chinese Holstein and Inner-Mongolia Sanhe cattle显示文摘Background: Bovine mastitis is the most common and costly disease of lactating cattle worldwide. Apart from milk somatic cell count(SCC) and somatic cell score(SCS), serum cytokines such as interleukin-17(IL-17) and interleukin-4(IL-4) may also be potential indicators for bovine mastitis. The present study was designed to investigate the effects of single nucleotide polymorphisms(SNPs) in bovine IL-17 F and IL-17 A genes on SCC, SCS and serum cytokines in Chinese Holstein and Inner-Mongolia Sanhe cattle, and to compare the m RNA expression variations of the cows with different genotypes.Results: A total of 464 lactating cows(337 Holstein and 127 Inner-Mongolia Sanhe cattle) were screened for SNPs identification and the data were analyzed using fixed effects of herd, parity, season and year of calving by general linear model procedure. The results revealed that SNP g.24392436 C > T in IL-17 F and SNP g.24345410 A > G in IL-17 A showed significant effects on SCC and IL-4 in Holstein(n = 337) and on IL-17 and IL-4 in Sanhe cattle(n = 127). The homozygous GG genotype of SNP g.24345410 A > G had significantly higher m RNA expression compared with the heterozygous AG genotype.Conclusions: The results indicate that IL-17 F and IL-17 A could be powerful candidate genes of mastitis resistance and the significant SNPs might be useful genetic markers against mastitis in both dairy and dual purpose cattle. | Tahir Usman Yachun Wang Chao Liu Yanghua He Xiao Wang Yichun Dong Hongjun Wu Airong Liu Ying Yu | 2017 | Journal of Animal Science and Biotechnology2017，8，2： | 4 |
| 8 | Recent progress in ZnO-based heterojunction ultraviolet light-emitting devices显示文摘Wide bandgap(3.37 eV)and high excitonbinding energy of ZnO(60 meV)make it a promising candidate for ultraviolet light-emitting diodes(LEDs)and low-threshold lasing diodes(LDs).However,the difficulty in producing stable and reproducible high-quality p-type ZnO has hindered the development of ZnO p–n homojunction LEDs.An alternative strategy for achieving ZnO electroluminescence is to fabricate heterojunction devices by employing other available p-type materials(such as p-GaN)or building new device structures.In this article,we will briefly review the recent progress in ZnO LEDs/LDs based on p–n heterostructures and metal–insulatorsemiconductor heterostructures.Some methods to improve device efficiency are also introduced in detail,including the introduction of Ag localized surface plasmons and single-crystalline nanowires into ZnO LEDs/LDs. | Yichun Liu Haiyang Xu Chunyang Liu Weizhen Liu | 2014 | Chinese Science Bulletin2014，59，12： | 4 |
| 9 | A numerical study on salinity stratification at the Oujiang River Estuary, China显示文摘The Oujiang River Estuary(ORE)is a macrotidal estuary with drastic variation of river discharge and large tidal range.Numerical simulations based on the unstructured grid,Finite-Volume,primitive equation Community Ocean Model(FVCOM)are conducted to investigate the intratidal and intertidal variations of salinity with an extremely upstream river boundary and large computational domain.The dynamic equation of potential energy anomaly is adopted to evaluate the stratification and mixing processes from model results.Meanwhile,the stability of estuarine stratification on different timescales and its spatial variation are studied using estuarine Richardson number and stratification parameter.The critical values of tidal range and river discharge that determine the stratification state are obtained.The critical values exhibit distinct spatial difference.The north branch of the ORE exhibits well-mixed conditions when the tidal range exceeds 3.8,4.0 and 4.6m at upper inlet,middle segment and the river mouth,respectively.When river discharge is below 280 m^3/s or exceeds 510 m^3/s,the upper part of the north branch is well-mixed sustainably.Near the river mouth,river discharge of 280 m^3/s is a rough critical value that separates well-mixed and stratified states.It is also concluded that periodic stratification exists in the North Channel.The lower estuary appears to be partially stratified at early ebb or early flood tide,and well-mixed in other tidal stages.The stratification only develops during early ebb in the upper segment.The enhancement of stratification is mainly caused by longitudinal advection and lateral velocity shear,while turbulent mixing and longitudinal tidal strain are the main factors of stratification attenuation. | Yichun Li Jingui Liu | 2019 | Acta Oceanologica Sinica2019，38，11： | 4 |

| 11 | Ultra-broadband metamaterial absorbers from long to very long infrared regime显示文摘Broadband metamaterials absorbers with high absorption,ultrathin thickness and easy configurations are in great demand for many potential applications.In this paper,we first analyse the coupling resonances in a Ti/Ge/Ti three-layer absorber,which can realise broadband absorption from 8 to 12 pm.Then we experimentally demonstrate two types of absorbers based on the Ti/Ge/Si_(3)N_(4)/Ti configuration.By taking advantage of coupling surface plasmon resonances and intrinsic absorption of lossy material Si_(3)N_(4),the average absorptions of two types of absorbers achieve almost 95%from 8 to 14μm(experiment result:78%from 6.5 to 13.5μm).In order to expand the absorption bandwidth,we further propose two Ti/Si/SiO_(2)/Ti absorbers which can absorb 92%and 87%of ultra-broadband light in the 14-30μm and 8-30μm spectral range,respectively.Our findings establish general and systematic strategies for guiding the design of metamaterial absorbers with excellent broadband absorption and pave the way for enhancing the optical performance in applications of infrared thermal emitters,imaging and photodetectors. | Yu Zhou Zheng Qin Zhongzhu Liang Dejia Meng Haiyang Xu David R.Smith Yichun Liu | 2021 | Light(Science & Applications)2021，10，8： | 3 |
| 12 | Efficacy of Carbamazepine Combined with Botulinum Toxin A in the Treatment of Blepharospasm and Hemifacial Spasm显示文摘Purpose:To observe the efficacy of the combined treatment of carbamazepine and botulinum toxin A for blepharospasm and hemifacial spasm. Methods:Fifty-eight patients with either blepharospasm or hemifacial spasm were randomly divided into treatment and control groups. In the treatment group, 30 patients were administered with local intramuscular injections of botulinum toxin A and oral carbamazepine 100 mg/time,3 times/day for 60 days. Twenty-eight subjects in the control group under-went local intramuscular injections of botulinum toxin A only. Results:After combined treatment, the complete remission rate was 90%, which was significantly higher than that of the of the control group (67.9% , P<0.05,χ2 =4.733). However, no statistical significance was noted regarding the duration of therapeutic effects between the treatment group (range 14~40 weeks; 19.2 weeks on average) and control group (range 12~36 weeks; 18 weeks on average). Conclusion:The combined therapy of carbamazepine and topical injections of botulinum toxin A had increased efficacy in the treatment of blepharospasm or hemifacial spasm, but had no significant effect in terms of the duration of the therapeutic effect. | Xianhua Li Shaochun Lin Yanfei Hu Liya Liu Jubo Liu Yichun Hong | 2012 | Eye Science2012，27，4： | 2 |
| 13 | Neutron irradiation-induced effects on the reliability performance of electrochemical metallization memory devices显示文摘In this work,electrochemical metallization memory(ECM)devices with an Ag/AgInSbTe(AIST)/amorphous carbon(a-C)/Pt structure were irradiated with 14 MeV neutrons.The switching reliability performance before and after neutron irradiation was compared and analyzed in detail.The results show that the irradiated memory cells functioned properly,and the initial resistance,the resistance at the low-resistance state(LRS),the RESET voltage and the data retention performance showed little degradation even when the total neutron fluence was as high as 2.5×1011 n/cm2.Other switching characteristics such as the forming voltage,the resistance at the high-resistance state(HRS),and the SET voltage were also studied,all of which merely showed a slight parameter drift.Irradiation-induced Ag ions doping of the a-C layer is proposed to explain the damaging effects of neutron irradiation.The excellent hard characteristics of these Ag/AIST/a-C/Pt-based ECM devices suggest potential beneficial applications in the aerospace and nuclear industries. | Ye Tao Xuhong Li Zhongqiang Wang Gang Li Haiyang Xu Xiaoning Zhao Ya Lin Yichun Liu | 2021 | Journal of Semiconductors2021，42，1： | 2 |

| 15 | Chlorine-anion doping induced multi-factor optimization in perovskites for boosting intrinsic oxygen evolution显示文摘The oxygen evolution reaction(OER) plays a crucial role in many electrochemical energy technologies,and creating multiple beneficial factors for OER catalysis is desirable for achieving high catalytic efficiency.Here,we highlight a new halogen-chlorine(Cl)-anion doping strategy to boost the OER activity of perovskite oxides.As a proof-of-concept,proper Cl doping at the oxygen site of LaFeO3(LFO) perovskite can induce multiple favorable characteristics for catalyzing the OER,including rich oxygen vacancies,increased electrical conductivity and enhanced Fe-O covalency.Benefiting from these factors,the LaFeO2.9-δCl0.1(LFOCl) perovskite displays significant intrinsic activity enhancement by a factor of around three relative to its parent LFO.This work uncovers the effect of Cl-anion doping in perovskites on promoting OER performance and paves a new way to design highly efficient electrocatalysts. | Yinlong Zhu Qian Lin Zhenbin Wang Dongchen Qi Yichun Yin Yu Liu Xiwang Zhang Zongping Shao Huanting Wang | 2021 | Journal of Energy Chemistry2021，30，1： | 2 |
| 16 | Analysis of Differences in Biochemical Components Between Yunnan and Kenya Tea Tree Varieties显示文摘With 16 Yunnan tea tree varieties and 5 Kenya tea tree varieties as test materials,the differences in biochemical components between Yunnan and Kenya tea tree varieties were compared and analyzed.The results showed that the coefficients of variation of tea polyphenols,amino acids,caffeine,water extract,gallic acid(GA),catechin(C),epicatechin(EC),epicatechin gallate(ECG),epigallocatechin(EGC),epigallocatechin gallate(EGCG)and total catechins in Yunnan tea tree varieties were greater than those in Kenyan tea trees.The contents of tea polyphenols,amino acids,caffeine,water extract,C,EC,EGC,EGCG and total catechins in Yunnan tea tree varieties had no significant differences from those in Kenyan tea trees varieties(P>0.05),while there were significant differences in the contents of GA and ECG between Yunnan tea tree varieties and Kenya tea tree varieties(P<0.05).Therefore,it could be predicted that GA and ECG might be one of the main characteristics of the differences in biochemical components between Yunnan tea tree varieties and Kenyan tea tree varieties.The cluster analysis results showed that when the genetic distance was 15,the 21 tested tea varieties could be divided into three groups with obvious biochemical differences. | Shengmei YANG Youyong LI Zhifen DUAN Yunxiu BAO Weiqiong SHANG Benying LIU Yichun TANG | 2020 | Agricultural Biotechnology2020，9，4： | 2 |
