| 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 | Mathematical Analysis on the Uniqueness of Reverse Algorithm for Measuring Elastic-plastic Properties by Sharp Indentation显示文摘The reverse analysis provides a convenient method to determine four elastic-plastic parameters through an indentation curve such as Young s modulus E, hardness H, yield strength σy and strain hardening exponent n. In this paper, mathematical analysis on a reverse algorithm from Dao model (Dao et al., Acta Mater., 2001, 49, 3899) was carried out, which thought that only when 20 ≤E*/σ0.033≤ 26 and 0.3 | Yongli Huang Xiaofang Liu Yichun Zhou Zengsheng Ma Chunsheng Lu | 2011 | Journal of Materials Science & Technology2011，27，7： | 7 |
| 3 | Comparison of CMAS corrosion and sintering induced microstructural characteristics of APS thermal barrier coatings显示文摘The microstructural features of high-temperature sintered and CaO-MgO-Al_2O_3-SiO_2(CMAS) corroded air plasma sprayed Y_2O_3 stabilized ZrO_2(YSZ) thermal barrier coatings(TBCs) under the thermal gradient condition were comparatively studied. As-sprayed YSZ has a lamellar structure and the lamellae are composed of closely aligned columnar crystals. The sintered and the CMAS corroded YSZ coatings maintain the t'-ZrO_2 phase as the as-sprayed YSZ coating. The sintered YSZ remains the lamellar structure with reduced interlamellar gaps and grains coarsening. After the CMAS corrosion, the top layer of the YSZ coating keeps its lamellar structure consisting of some columnar grains with the CMAS infiltration into the intergrain gaps and the formation of striped Zr_2Y_2 O_7. The typical lamellar structure transforms into more equiaxed grains in the middle and bottom layers of the ceramic coating along with significant infiltration of amorphous CMAS and anorthite formation in the bottom layer owing to the high contents of Ca and Al. | Yiyou Wu Hua Luo Canying Cai Yanguo Wang Yichun Zhou Li Yang Guangwen Zhou | 2019 | Journal of Materials Science & Technology2019，35，3： | 5 |
| 4 | A new method to determine the elastoplastic properties of ductile materials by conical indentation显示文摘Based on load-displacement curves,indentation is widely used to extract the elastoplastic properties of materials.It is generally believed that such a measure is non-unique and a full stress-strain curve cannot be obtained using plural sharp and deep spherical indenters.In this paper we show that by introducing an additional dimensionless function of A/A (the ratio of residual area to the area of an indenter profile) in the reverse analysis,the elastoplastic properties of several unknown materials that exhibit visually indistinguishable load-displacement curves can be uniquely determined with a sharp indentation. | MA ZengSheng ZHOU YiChun LONG ShiGuo LU ChunSheng | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，6： | 4 |
| 5 | Mesoscopic superelasticity,superplasticity,and superrigidity显示文摘Atomic-undercoordination-induced local bond contraction,bond strength gain,and the associated temperature (T)-dependent atomic-cohesive-energy and binding-energy-density are shown to originate intrinsically the exotic paradox of superplasticity,superelasticity,and superrigidity demonstrated by solid sizing from monatomic chain to mesoscopic grain.The paradox follows these relationships:(ε(K,T)y(K,T)σ(K,T))∝(exp(B/△T_(mk)),(η_1△T_(mk))d~(-3),[1+AK~(-2/2)exp(△T_(mk)/T)]△T_(mk)d~(-3)),(Plastic strain)(Elastic modulus)(Yield stress,IHPR)where A,B,η1,d and△T_(mk)=Tm(K) Tare size (K)-dependent physical parameters.Tm (K) is the melting point.Mechanical work hardening during compressing and self-heating during stretching modulate the measured outcome extrinsically.Superplasticity dominates in the solid-quasimolten-liquid transition state.The competition between the accumulation and annihilation of dislocations activates the inverse Hall-Petch relationship.Therefore,it is essential for one to discriminate the intrinsic competition between the local bond energy density gain and the atomic cohesive energy loss from the extrinsic factors of pressure and temperature in dealing with atomistic mechano-thermo dynamics. | MA ZengSheng ZHOU ZhaoFeng HUANG YongLi ZHOU YiChun SUN ChangQing | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，6： | 3 |
| 6 | Prediction of Failure Modes during Deep Drawing of Metal Sheets with Nickel Coating显示文摘To optimize the process parameters,it is necessary to exactly predict failure modes during deep drawing of coated metal sheets,where two main failure forms are fracture and wrinkling.In this paper,finite element simulations based on continuous damage mechanics were used to study the failure behavior during a cylindrical deep drawing of metal sheets with nickel coating.It is shown that taking the effect of blank holder force into account,these two failure modes can be predicted.The simulation results are well consistent with that obtained from experiments. | Jie Wu Zengsheng Ma Yichun Zhou Chunsheng Lu | 2013 | Journal of Materials Science & Technology2013，29，11： | 3 |
| 7 | 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 | Ferroelastic domain identification and toughening mechanism for yttrium tantalate–zirconium oxide显示文摘Yttrium tantalate(YTaO_(4))is the next generation of higher service temperature thermal barrier coatings(TBCs)materials due to its smaller volume effect in phase change,lower thermal conductivity and unique ferroelastic domain structure.However,the low fracture toughness limits its application.We first characterized the diffraction patterns of variants,and two variants(M_(1)and M_(2))observed in transmission electron microscopy(TEM)results were determined from four possible variants by mechanical derivation.The role of Zr^(4+)doping in ferroelastic toughening was explained in detail.With the increase of Zr^(4+)doping concentration,the monoclinic angle β and the domain rotation angleαdecrease,respectively.The spontaneous strain component and the principal strain in the main space also have a similar decreasing trend.The decrease of the ferroelastic domain inversion energy barrier is beneficial to the improvement of fracture toughness.Combining the results of Vickers indentation,we found that Zr^(4+)could be enriched at the domain boundary to inhibit the generation of cracks.An appropriate amount of Zr^(4+)is conducive to the improvement of fracture toughness,and the excessive Zr^(4+)will reduce the fracture toughness due to the generation of by-product t-ZrO_(2).So,the optimal composition is Y_(0.44)Ta_(0.44)Zr_(0.12)O_(2) and the best fracture toughness(2.9–3.8MPa m^(1/2))is equivalent to the commercial 8YSZ.This result will promote the application of a new generation of TBCs. | Cheng Luo Cong Li Ke Cao Junbao Li Junhui Luo Qinghua Zhang QianQian Zhou Fan Zhang Lin Gu Li Yang Yichun Zhou | 2022 | Journal of Materials Science & Technology2022，，32： | 1 |

| 18 | A nomogram predicting clinical pregnancy in the first fresh embryo transfer for women undergoing in vitro fertilization and intracytoplasmic sperm injection(IVF/ICSI) treatments显示文摘The extent to which factors affect the probability of clinical pregnancy in the first fresh embryo transfer after assisted conception is unknown.In order to examine the predictors of clinical pregnancy,a retrospective cohort study was launched between January 1,2013 and December 31,2016 in four infertility clinics including 19837 in vitro fertilization and intracytoplasmic sperm injection(IVF/ICSI)fresh cycles with known outcomes and relevant records.A multivariable logistic regression was used to select the most significant predictors in the final nomogram for predicting clinical pregnancy.Furthermore,the model was validated by an independent validation set and the performance of the model was evaluated by the receiver operating characteristic(ROC)curves along with the area under the ROC curve(AUC)and calibration plots.In a training set including 17854 participants,we identified that female age,tubal factor,number of embryos transferred,endometrial thickness and number of good-quality embryos were independent predictors for clinical pregnancy.We developed a nomogram using these five factors and the predictive ability was 0.66 for AUC(95%CI=0.64−0.68),which was independently validated in the validation set(AUC=0.66,95%CI=0.65−0.68).Our results show that some specific factors can be used to provide infertile couples with an accurate assessment of clinical pregnancy following assisted conception and facilitate to guide couples and clinicians. | Fang Wu Feng Liu Yichun Guan Jiangbo Du Jichun Tan Hong Lv Qun Lu Shiyao Tao Lei Huang Kun Zhou Yankai Xia Xinru Wang Hongbing Shen Xiufeng Ling Feiyang Diao Zhibin Hu Guangfu Jin | 2019 | The Journal of Biomedical Research2019，33，6： | 1 |
| 19 | Determination of phase diagrams using the diffusion couple technique显示文摘It has been demonstrated that the diffusion couple technique is a powerful and efficient approach in establishing phase relationships of ternary systems. Accurate data on the phase equilibria can be obtained if the appropriate alloys are employed as end members of the diffusion couple. It is desirable to combine the diffusion couple technique with an investi- gation of the afterwards selected equilibrated alloys so that the precision and reliability of the obtained information about a ternary isotherm could be guaranteed. | XU Honghu DU Yong ZHOU Yichun JIN Zhanpeng | 2006 | Rare Metals2006，25，5： | 1 |
| 20 | Characterization of domain distributions by second harmonic generation in ferroelectrics显示文摘Domain orientations and their volume ratios in ferroelectrics are recognized as a compelling topic recently for domain switching dynamics and domain stability in devices application.Here,an optimized second harmonic generation method has been explored for ferroelectric domain characterization.Combing a unique theoretical model with azimuth-polarization-dependent second harmonic generation response,the complex domain components and their distributions can be rigidly determined in ferroelectric thin films.Using the proposed model,the domain structures of rhombohedral BiFeO_(3) films with 71°and 109°domain wall,and,tetragonal BiFeO_(3),Pb(Zr_(0.2)Ti_(0.8))O_(3),and BaTiO_(3) ferroelectric thin films are analyzed and the corresponding polarization variants are determined.This work could provide a powerful and all-optical method to track and evaluate the evolution of ferroelectric domains in the ferroelectric-based devices. | Yuan Zhang Yi Zhang Quan Guo Xiangli Zhong Yinghao Chu Haidong Lu Gaokuo Zhong Jie Jiang Congbing Tan Min Liao Zhihui Lu Dongwen Zhang Jinbin Wang Jianmin Yuan Yichun Zhou | 2018 | npj Computational Materials2018，，1： | 1 |
