| 1 | Wall shear stress in intracranial aneurysms and adjacent arteries显示文摘Hemodynamic parameters play an important role in aneurysm formation and growth. However, it is difficult to directly observe a rapidly growing de novo aneurysm in a patient. To investigate possible associations between hemodynamic parameters and the formation and growth of intracranial aneurysms, the present study constructed a computational model of a case with an internal carotid artery aneurysm and an anterior communicating artery aneurysm, based on the CT angiography findings of a patient. To simulate the formation of the anterior communicating artery aneurysm and the growth of the internal carotid artery aneurysm, we then constructed a model that virtually removed the anterior communicating artery aneurysm, and a further two models that also progressively decreased the size of the internal carotid artery aneurysm. Computational simulations of the fluid dynamics of the four models were performed under pulsatile flow conditions, and wall shear stress was compared among the different models. In the three aneurysm growth models, increasing size of the aneurysm was associated with an increased area of low wall shear stress, a significant decrease in wall shear stress at the dome of the aneurysm, and a significant change in the wall shear stress of the parent artery. The wall shear stress of the anterior communicating artery remained low, and was significantly lower than the wall shear stress at the bifurcation of the internal carotid artery or the bifurcation of the middle cerebral artery. After formation of the anterior communicating artery aneurysm, the wall shear stress at the dome of the internal carotid artery aneurysm increased significantly, and the wall shear stress in the upstream arteries also changed significantly. These findings indicate that low wall shear stress may be associated with the initiation and growth of aneurysms, and that aneurysm formation and growth may influence hemodynamic parameters in the local and adjacent arteries. | Fuyu Wang Bainan Xu Zhenghui Sun Chen Wu Xiaojun Zhang | 2013 | Neural Regeneration Research2013，8，11： | 6 |
| 2 | Terahertz wavefront shaping with multi-channel polarization conversion based on all-dielectric metasurface显示文摘Polarization manipulation of electromagnetic wave or polarization multiplexed beam shaping based on metasurfaces has been reported in various frequency bands.However,it is difficult to shape the beam with multi-channel polarization conversion in a single metasurface.Here,we propose a new method for terahertz wavefront shaping with multi-channel polarization conversion via all-silicon metasurface,which is based on the linear shape birefringence effect in spatially interleaved anisotropic meta-atoms.By superimposing the eigen-and non-eigen-polarization responses of the two kinds of meta-atoms,we demonstrate the possibility for high-efficiency evolution of several typical polarization states with two independent channels for linearly polarized waves.The measured polarization conversion efficiency is higher than 70%in the range of 0.9–1.3 THz,with a peak value of 89.2%at 1.1 THz.In addition,when more other polarization states are incident,combined with the integration of sub-arrays,we can get more channels for both polarization conversion and beam shaping.Simulated and experimental results verify the feasibility of this method.The proposed method provides a new idea for the design of terahertz multi-functional metadevices. | JIE LI CHENGLONG ZHENG JITAO LI GUOCUI WANG JINGYU LIU ZHEN YUE XUANRUO HAO YUE YANG FUYU LI TINGTING TANG YATING ZHANG YAN ZHANG JIANQUAN YAO | 2021 | Photonics Research2021，9，10： | 5 |

| 8 | Simulation Research on Fire Evacuation of Large Public Buildings Based on Building Information Modeling显示文摘Reasonable evacuation strategies are important in reducing casualties in the event of a fire.In this work,we conduct a simulation of a fire evacuation of a large public building based on the building information modeling technology to find the best evacuation strategy.We identify the tolerance limit of evacuees in case of a fire as the basis of the simulation using the fire dynamics simulator software.The following four evacuation strategies are proposed and simulated:stratified evacuation only by stairs,stratified evacuation mainly by stairs and supplemented by fire elevators,holistic evacuation only by stairs,and holistic evacuation mainly by stairs and supplemented by fire elevators.The case study of a college canteen shows that if 10%of evacuees(mainly elderly people who walk slowly and children who take up less space)are instructed to evacuate via fire elevators and the other 90%of evacuees(young men and women who move fast)use the stairs,the evacuation time can be reduced to a minimum.Some improvements in the design drawing result in the enhanced efficiency of the proposed strategy.The findings of this work are of great significance for the optimization of the structural design of large public buildings and provide some references for emergency evacuation. | Fuyu Wang Xiao Xu Mengkai Chen Juma Nzige Fawen Chong | 2021 | Complex System Modeling and Simulation2021，1，2： | 1 |
| 9 | Nanometer-scale gradient atomic packing structure surrounding soft spots in metallic glasses显示文摘The hidden order of atomic packing in amorphous structures and how this may provide the origin of plastic events have long been a goal in the understanding of plastic deformation in metallic glasses.To pursue this issue,we employ here molecular dynamic simulations to create three-dimensional models for a few metallic glasses where,based on the geometrical frustration of the coordination polyhedra,we classify the atoms in the amorphous structure into six distinct species,where“gradient atomic packing structure”exists.The local structure in the amorphous state can display a gradual transition from loose stacking to dense stacking of atoms,followed by a gradient evolution of atomic performance.As such,the amorphous alloy specifically comprises three discernible regions:solid-like,transition,and liquid-like regions,each one possessing different types of atoms.We also demonstrate that the liquid-like atoms correlate most strongly with fertile sites for shear transformation,the transition atoms take second place,whereas the solid-like atoms contribute the least because of their lowest correlation level with the liquid-like atoms.Unlike the“geometrically unfavored motifs”model which fails to consider the role of medium-range order,our model gives a definite structure for the so-called“soft spots”,that is,a combination of liquid-like atoms and their neighbors,in favor of quantifying and comparing their number between different metallic glasses,which can provide a rational explanation for the unique mechanical behavior of metallic glasses. | Binbin Wang Liangshun Luo Enyu Guo Yanqing Su Mingyue Wang Robert O.Ritchie Fuyu Dong Liang Wang Jingjie Guo Hengzhi Fu | 2018 | npj Computational Materials2018，，1： | 1 |
| 10 | Molecular cytogenetic analyses of two new wheat-rye 6RL translocation lines with resistance to wheat powdery mildew显示文摘Rye(Secale cereale)is a valuable gene donor for wheat improvement,especially for its resistance to diseases.Developing rye-derived resistance sources is important for wheat breeding.In the present study,two wheat-rye derivatives,designated JS016 and JS110,were produced by crossing common wheat cultivar Yangmai 23 with Pakistani rye accession W2A.Using sequential genomic in situ hybridization(GISH)and multicolor fluorescence in situ hybridization(mc-FISH),JS016 and JS110 were identified as a T6BS.6RL translocation line and a T6BS.6BL6RL translocation line,respectively.Ten newly 6RL chromosome arm-specific markers were developed and used to confirm the 6RL translocation.The wheat 55K single-nucleotide polymorphism(SNP)array further verified the molecular cytogenetic identification results above and clarified their breakpoints at 430.9 and 523.0 Mb of chromosome 6B in JS016 and JS110,respectively.Resistance spectrum and allelism test demonstrated that JS016 and JS110 possessed novel powdery mildew resistance gene(s)that was derived from the 6RL translocation but differed from Pm20.Moreover,JS016 and JS110 had better agronomic traits than the previously reported 6RL translocation line carrying Pm20.To efficiently transfer and detect the 6RL translocation from JS016 and JS110,one 6RL-specific Kompetitive allele specific PCR(KASP)marker was developed and validated in high throughput marker-assisted selection(MAS). | Shanying Zhu Haonan Du Fuyu Su Jin Wang Qingfeng Meng Tianlei Liu Rui Guo Zhaozhao Chen Huanhuan Li Wenxuan Liu Pengtao Ma Huagang He | 2023 | The Crop Journal2023，11，2： | 1 |

| 13 | Extraordinarily stable and wide-temperature range sodium/potassium-ion batteries based on 1D SnSe2-SePAN composite nanofibers显示文摘Developing electrodes with long lifespan and wide-temperature adaptability is crucial important to achieve high-performance sodium/potassium-ion batteries(SIBs/PIBs).Herein,the SnSe2-SePAN composite was fabricated for extraordinarily stable and wide-temperature range SIBs/PIBs through a coupling strategy between controllable electrospinning and selenylation,in which SnSe2 nanoparticles were uniformly encapsulated in the SePAN matrix.The unique structure of SnSe2-SePAN not only relieves drastic volume variation but also guarantees the structural integrity of the composite,endowing SnSe2-SePAN with excellent sodium/potassium storage properties.Consequently,SnSe2-SePAN displays a high sodium storage capacity and excellent feasibility in a wide working temperature range(-15 to 60℃:300 mAh g^(-1)/700 cycles/-15℃;352 mAh g^(-1)/100 cycles/60℃at 0.5 A g^(-1)).At room temperature,it delivers a record-ultralong cycling life of 192 mAh g^(-1)that exceeds 66000 cycles even at 15 A g^(-1).It exhibits extremely superb electrochemical performance in PIBs(157 mAh g^(-1)exceeding 15000 cycles at 5 A g^(-1)).The ex situ XRD and TEM results attest the conversion-alloy mechanism of SnSe2-SePAN.Also,computational calculations verify that SePAN takes an important role in intensifying the electrochemical performance of SnSe2-SePAN electrode.Therefore,this study breaks new ground on solving the polyselenide dissolution issue and improving the wide temperature workable performance of sodium/potassium storage. | Yiyi Wang Fuyu Xiao Xi Chen Peixun Xiong Chuyuan Lin Hong-En Wang Mingdeng Wei Qingrong Qian Qinghua Chen Lingxing Zeng | 2023 | InfoMat2023，5，9： | 1 |
| 14 | A critical review of vanadium-based electrode materials for rechargeable magnesium batteries显示文摘Rechargeable magnesium batteries(RMBs)are one of the most promising next-generation energy storage devices due to their high safety and low cost.With a large family and versatile advantageous structures,vanadium-based compounds are highly competitive as electrode materials of RMBs.This review summa-rizes the structural characteristics,electrochemical performance,and refinement methods of vanadium-based materials,including vanadium oxides,vanadium sulfides,vanadates,vanadium phosphates,and vanadium spinel compounds,as RMB cathodes.Although relatively less,vanadium-based materials as RMB anodes are also introduced.According to the application requirements of RMBs,present common strategies are concluded to improve the electrochemical performance of vanadium-based materials;the probably promising development directions are also proposed,which are not limited only to the elec-trode materials,but also the compatible electrolytes and separator materials.In the near future,RMBs are expected from their large-scale application,standing at the forefront of the energy storage era. | Xiu-Fen Ma Hong-Yi Li Weiwei Ren Daibo Gao Fuyu Chen Jiang Diao Bing Xie Guangsheng Huang Jingfeng Wang Fusheng Pan | 2023 | Journal of Materials Science & Technology2023，，22： | 0 |

| 16 | Ultrasonic Degradation of Methyl Orange in Presence of Y2O3 Doping Anatase TiO2 Catalyst显示文摘Various affecting factors and degradation mechanism were studied on ultrasonic degradation of methyl orange adopting Y2O3 doping anatase TiO2 catalyst prepared in laboratory.In the experiment, the UV-VIS spectrophotometer was used to follow and inspect the degradation process of methyl orange.The results indicate that the ultrasonic degradation ratios of methyl orange in the presence of anatase TiO2 catalyst are much better than those without catalyst.Moreover, the catalytic performance of Y2O3 doping anatase TiO2 catalyst is obviously higher than that of anatase TiO2 catalyst without doping.The optimal conditions were adopted in this work and the degradation and COD elimination ratio of methyl orange got to98% and 99.0% in 90 min, respectively. | Wang Jun Guo Baodong Pan Zhijun Liu Zhenrong Wen Fuyu Zhang Zhaohong | 2004 | Journal of Rare Earths2004，22，z1： | 0 |
| 17 | 不同胆管空肠吻合技术治疗成人Ⅰ型胆总管囊肿的比较分析显示文摘目的:比较囊肿完全切除与不完全切除(残留近端1 cm胆总管囊壁)的Roux-en-Y胆管空肠吻合治疗成人Ⅰ型胆总管囊肿的安全性和可行性。方法:回顾性分析1998年1月至2015年12月间收治的267例成人Ⅰ型胆总管囊肿患者的病例资料,其中171例行囊肿完全切除的Rouxen-Y胆管空肠吻合术(PBD 0-cm组),96例行囊肿不完全切除的Rouxen-Y胆管空肠吻合术(PBD 1-cm组)。比较两组患者术后短期及长期并发症发生情况。结果:两组患者在手术时间和吻合口直径方面的差异均无统计学意义。PBD 1-cm组围手术期并发症发生率显著高于PBD 0-cm组(28.1%vs 14.0%,P=0.005),尤其是术后胆管炎(7.3%vs 1.2%,P=0.021)。两组患者术后吻合口狭窄、反流性胆管炎、肝内胆管结石和胆漏等长期并发症的差异均无统计学意义(均P>0.05)。PBD 1-cm组和PBD 0-cm组各有1例患者分别于术后5月和术后25月出现胰胆管恶变。而PBD 1-cm组有1例患者于术后10月出现吻合口恶变。结论:虽然保留部分囊壁可以降低Ⅰ型胆总管囊肿切除术中的吻合难度,但由于相对较高的术后并发症发生率和恶变概率,该吻合方式值得商榷。对于Ⅰ型胆总管囊肿患者,囊肿完全切除后以健康的近端胆管进行吻合是必要的。 | Wenjie Ma Yongqiong Tan Anuj Shrestha Fuyu Li Rongxing Zhou Junke Wang Haijie Hu Qin Yang | 2018 | Gastroenterology Report2018，6，1： | 0 |
| 18 | Manipulating internal flow units toward favorable plasticity in Zr-based bulk-metallic glasses by hydrogenation显示文摘This work intends to manipulate the internal flow units in Zr_(55)Cu_(30)Ni_(5)Al_(10)bulk-metallic glasses(BMGs)through plasma-assisted hydrogenation to generate a positive microalloying effect on plasticity.Based on the cooperative shear model theory,serration-flow statistics during nanoindentation loading and creep tests during the holding stage were used to analyze the influence of hydrogen on the behavior of flow units in BMGs.Experimental observations showed that the hydrogen in the Zr_(55)Cu_(30)Ni_(5)Al_(10)BMGs caused mechanical softening,plasticity improvement,and structural relaxation.Analysis also showed that the average volume,size,and activation energy of internal flow units in the BMGs all increased as a result of the increase in the hydrogen content.The hydrogenation in the BMGs was found to lead to a prolifera-tion of shear bands,which promoted plasticity.The aggregation of these internal flow units reduced the stress required for plastic deformation through shear bands,ultimately causing softening and structural relaxation. | Fuyu Dong Yuexin Chu Mengyuan He Yue Zhang Weidong Li Peter K.Liaw Binbin Wang Liangshun Luo Yanqing Su Robert O.Ritchie Xiaoguang Yuan | 2022 | Journal of Materials Science & Technology2022，，7： | 0 |
| 19 | Small extracellular vesicles secreted by urine-derived stem cells enhanced wound healing in aged mice by ameliorating cellular senescence显示文摘Regeneration of chronic skin wounds in tissue is still a key challenge in regenerative medicine because of the accumulation of senescent cells and increasing secretion of s¨enescence-associated secretory phenotype(SASP)in the wound site.Recently,some studies have reported that small extracellular vesicles(sEVs)derived from stem cells can alleviate cellular senescence with very low risk of tumorigenesis and immune responses.As our previous studies have shown that urine-derived stem cells(USCs)can be obtained easily and noninvasively and sEVs derived from USCs(USC-sEVs)have capabilities of regenerating tissue injuries,using USC-sEVs to enhance chronic skin wound healing in aged tissue might be a feasible and efficient strategy.Therefore,in this study,the USC-sEVs were collected and firstly loaded in a human acellular amniotic membrane(HAAM)for controlled releasing and locating the USC-sEVs in the wound site before they were implanted into a chronic skin wound in aged mice.In vivo results showed that the USC-sEVs in HAAM could effectively accelerate the wound healing by ameliorating cellular senescence and reducing the secretion of SASP in the aged skin wounds.To elucidate the mechanism,USC-sEVs were used to in vitro culture human dermal fibroblasts(HDFs)and results showed that USC-sEVs could rejuvenate senescent fibroblasts by reversing the aging phenotypes of senescent HDFs and efficiently reducing the secretion of SASP after they activated the Sirt1 pathway.Therefore,USC-sEVs are efficient for enhancing wound healing in aged mice by ameliorating cellular senescence. | Yongjin Sun Juntao Zhang Bi Chen Yunlong Yang Haiyan Li Xin Niu Qing Li Weidong Wu Zongping Xie Yunfeng Chen Fuyue Wu Yang Wang | 2021 | Journal of Materials Science & Technology2021，，4： | 0 |
