| 1 | Model test and numerical simulation on the dynamic stability of the bedding rock slope under frequent microseisms显示文摘Shake table testing was performed to investigate the dynamic stability of a mid-dip bedding rock slope under frequent earthquakes. Then, numerical modelling was established to further study the slope dynamic stability under purely microseisms and the influence of five factors, including seismic amplitude, slope height, slope angle, strata inclination and strata thickness, were considered. The experimental results show that the natural frequency of the slope decreases and damping ratio increases as the earthquake loading times increase. The dynamic strength reduction method is adopted for the stability evaluation of the bedding rock slope in numerical simulation, and the slope stability decreases with the increase of seismic amplitude, increase of slope height, reduction of strata thickness and increase of slope angle. The failure mode of a mid-dip bedding rock slope in the shaking table test is integral slipping along the bedding surface with dipping tensile cracks at the slope rear edge going through the bedding surfaces. In the numerical simulation, the long-term stability of a mid-dip bedding slope is worst under frequent microseisms and the slope is at risk of integral sliding instability, whereas the slope rock mass is more broken than shown in the shaking table test. The research results are of practical significance to better understand the formation mechanism of reservoir landslides and prevent future landslide disasters. | Deng Zhiyun Liu Xinrong Liu Yongquan Liu Shulin Han Yafeng Liu Jinhui Tu Yiliang | 2020 | Earthquake Engineering and Engineering Vibration2020，19，4： | 3 |
| 2 | Influence of Shot Peening Treatment on the Fatigue and Corrosion Resisting Properties of 2Cr13 Stainless Steel显示文摘In the present paper,shot peening treatments were used to strengthen the steel surface,and the influence on the fatigue and corrosion resisting properties of 2Cr13 stainless steel was examined.The residual stress and the surface roughness were investigated by XRD and AFM.The characteristics of fatigue and corrosion resistance have also been analyzed by bending fatigue and salt spray tests.The result reveals that the fatigue limit of the samples is improved dramatically with the increasing of the peening strength by 7.5%.Meanwhile,the peenging angle has no evident influence on the fatigue properties.Compared with the untreated samples,the acid corrosion weight loss of the samples after the shot peening treatment is decreased almost by 90%.From the above experimental results proper shot peening would improve not only the fatigue property but also the corrosion resistance of 2Cr13-typed stainless steel. | Liu Mingxia Zhang Haicun Liu Daoxin Han Zengfu Zhi Jinhua Guo Wenyong Zhou Yafeng | 2012 | 稀有金属材料与工程2012，41，S1： | 2 |
| 3 | Generation of transgenic wheat resistant to wheat yellow mosaic virus and identification of gene silence induced by virus infection显示文摘The plasmid containing the promoter Actl, the coat protein (cp) gene of wheat yellow mosaic virus (WYMV) and the selectable bar gene, was delivered via particle bombardment, directly into immature embryos of a wheat culti-vars. PCR and PCR-RFLP were employed to screen the existence of the cp gene in T0 and T1 generations. Seeds from the positive T1 plants were sowed in fields heavily contaminated with WYMV to detect their resistance. In field trial of virus infection, one of the transgenic wheat lines, P8-T2, exhibited highly disease-resistance. Western blot and RT-PCR analysis showed that the expression level of cp gene in the resistant transgenic line was reduced greatly compared to those susceptible to WYMV infection. This provided evidence to presume that the resistance obtained by the transgenic wheat line was stimulated by the mechanism of the virus induced gene silencing. | DONG Jin HE Zhentian HAN Chenggui CHEN Xiulan ZHANG Lingdi LIU Weihua HAN Yuepeng WANG Jinrong ZHAI Yafeng YU Jialin LIU Yi XIAO Yueyan | 2002 | Chinese Science Bulletin2002，47，17： | 2 |
| 4 | Mechanical behaviours of sandstone containing intersecting fissures under uniaxial compression显示文摘Predicting rock cracking is important for assessing the stability of underground engineering.The effects of the intersecting angle a and the distribution orientation angleβof intersecting fissures on the uniaxial compressive strength and the failure characteristics of sandstone containing intersecting fissures are investigated through laboratory experiments and two-dimensional particle flow code(PFC2D).The relationship between the mechanical properties of sandstone and the intersecting angle a and the distribution orientation angleβis analysed.Crack initiation forms and the final failure modes are then categorised and determined via empirical methods.In addition,the cracking processes of intersecting fissures with different a andβvalues are discussed.The results show that variations in the peak stress,peak strain,average modulus,and crack initiation stress of sandstone containing intersecting fissures show a“moth”shape in the space of the a-β-mechanical parameters.Two crack initiation forms are identified:inner tip cracking(usually accompanied by one outer tip cracking)and only outer tips cracking.Two failure modes are observed:(1)the main fracture planes are created at the inner tip and one outer tip,and(2)the main fracture planes are formed at the two outer tips.Two main crack evolution processes of sandstone containing intersecting fissures under uniaxial compression are found.Approaches for quickly determining the crack initiation form and the failure mode are proposed.The combination of the determination equations for the crack initiation form and the failure mode can be used to predict the crack evolution.The approach for determining the crack evolution processes is hence proposed with acceptable precision. | Fei Xiong Xinrong Liu Xiaohan Zhou Guangyi Lin Dongshuang Liu Yafeng Han Bin Xu Chunmei He Zijuan Wang | 2022 | Journal of Rock Mechanics and Geotechnical Engineering2022，14，2： | 1 |
| 5 | Modulating the C-terminus of DEP1 synergistically enhances grain quality and yield in rice显示文摘Grain shape is a key breeding target that influences both grain yield and appearance quality in rice. Breeding for long-slender grains is an effective strategy to improve grain quality (Jain et al., 2004;Wang et al., 2012, 2015a). In the past two decades, several quantitative trait loci (QTLs) responsible for grain size and shape have been identified, including GS3 (Fan et al., 2006), GS5 (Li et al., 2011). | Haixiang Huang Yafeng Ye Wenzhen Song Qi Li Ruixi Han Chenchen Wu Shuoxun Wang Jianping Yu Xueying Liu Xiangdong Fu Qian Liu Kun Wu | 2022 | Journal of Genetics and Genomics2022，49，5： | 1 |
| 6 | Worldwide impacts of atmospheric vapor pressure deficit on the interannual variability of terrestrial carbon sinks显示文摘Interannual variability of the terrestrial ecosystem carbon sink is substantially regulated by various environmental variables and highly dominates the interannual variation of atmospheric carbon dioxide(CO_(2))concentrations.Thus,it is necessary to determine dominating factors affecting the interannual variability of the carbon sink to improve our capability of predicting future terrestrial carbon sinks.Using global datasets derived from machine-learning methods and process-based ecosystem models,this study reveals that the inter annual variability of the atmospheric vapor pressure deficit(VPD)was significantly negatively correlated with net ecosystem production(NEP)and substantially impacted the inter annual variability of the atmospheric CO_(2)growth rate(CGR).Further analyses found widespread constraints of VPD interannual variability on terrestrial gross primary production(GPP),causing VPD to impact NEP and CGR.Partial correlation analysis confirms the persistent and widespread impacts of VPD on terrestrial carbon sinks compared to other environmental variables.Current Earth system models underestimate the interannual variability in VPD and its impacts on GPP and NEP.Our results highlight the importance of VPD for terrestrial carbon sinks in assessing ecosystems'responses to future climate conditions. | Bin He Chen Chen Shangrong Lin Wenping Yuan Hans WChen Deliang Chen Yafeng Zhang Lanlan Guo Xiang Zhao Xuebang Liu Shilong Piao Ziqian Zhong Rui Wang Rui Tang | 2022 | National Science Review2022，9，4： | 1 |

| 8 | Adsorption Site Regulations of[W–O]‑Doped CoP Boosting the Hydrazine Oxidation‑Coupled Hydrogen Evolution at Elevated Current Density显示文摘Hydrazine oxidation reaction(HzOR)assisted hydrogen evolution reaction(HER)offers a feasible path for low power consumption to hydrogen production.Unfortunately however,the total electrooxidation of hydrazine in anode and the dissociation kinetics of water in cathode are critically depend on the interaction between the reaction intermediates and surface of catalysts,which are still challenging due to the totally different catalytic mechanisms.Herein,the[W–O]group with strong adsorption capacity is introduced into CoP nanoflakes to fabricate bifunctional catalyst,which possesses excellent catalytic performances towards both HER(185.60 mV at 1000 mA cm^(−2))and HzOR(78.99 mV at 10,00 mA cm^(−2))with the overall electrolyzer potential of 1.634 V lower than that of the water splitting system at 100 mA cm^(−2).The introduction of[W–O]groups,working as the adsorption sites for H2O dissociation and N2H4 dehydrogenation,leads to the formation of porous structure on CoP nanoflakes and regulates the electronic structure of Co through the linked O in[W–O]group as well,resultantly boosting the hydrogen production and HzOR.Moreover,a proof-of-concept direct hydrazine fuel cell-powered H_(2) production system has been assembled,realizing H_(2)evolution at a rate of 3.53 mmol cm^(−2)h^(−1)at room temperature without external electricity supply. | Ge Meng Ziwei Chang Libo Zhu Chang Chen Yafeng Chen Han Tian Wenshu Luo Wenping Sun Xiangzhi Cui Jianlin Shi | 2023 | Nano-Micro Letters2023，15，11： | 0 |
| 9 | Preparation of conductive and transparent dipeptide hydrogels for wearable biosensor显示文摘Conductive and transparent dipeptide hydrogels are desirable building blocks to prepare soft electronic devices and wearable biosensors due to their excellent biocompatibility,multi-functionality,and physiochemical properties similar to those of body tissues.However,the preparation of such hydrogels featuring high conductivity and transparency is a huge challenge because of the hydrophobic feature of conductive additives making the doping process difficult.To overcome this issue,hydrophilic conductive polydopamine(PDA)-doped polypyrrole(PPy)nanoparticles are introduced into the dipeptide hydrogel networks to form conductive nanofibrils in situ to achieve a good level of hydrophilic templating of the hydrogel networks.This tech-nique creates a complete conductive network and allows visible light to pass through.The strategy proposed herein not only endows the dipeptide hydrogel with good conductivity and high transparency,but also provides a great potential application of conductive dipeptide hydrogels for body-adhered signal detection,as evidenced by the experimental data. | Yafeng Jing Anhe Wang Jieling Li Qi Li Qingquan Han Xuefang Zheng Hongyu Cao Shuo Bai | 2022 | Bio-Design and Manufacturing2022，5，1： | 0 |
| 10 | Review on application progress of federated learning model and security hazard protection显示文摘Federated learning is a new type of distributed learning framework that allows multiple participants to share training results without revealing their data privacy.As data privacy becomes more important,it becomes difficult to collect data from multiple data owners to make machine learning predictions due to the lack of data security.Data is forced to be stored independently between companies,creating“data silos”.With the goal of safeguarding data privacy and security,the federated learning framework greatly expands the amount of training data,effectively improving the shortcomings of traditional machine learning and deep learning,and bringing AI algorithms closer to our reality.In the context of the current international data security issues,federated learning is developing rapidly and has gradually moved from the theoretical to the applied level.The paper first introduces the federated learning framework,analyzes its advantages,reviews the results of federated learning applications in industries such as communication and healthcare,then analyzes the pitfalls of federated learning and discusses the security issues that should be considered in applications,and finally looks into the future of federated learning and the application layer. | Aimin Yang Zezhong Ma Chunying Zhang Yang Han Zhibin Hu Wei Zhang Xiangdong Huang Yafeng Wu | 2023 | Digital Communications and Networks2023，9，1： | 0 |
| 11 | Generation of irregular particle packing with prescribed statistical distribution, spatial arrangement, and volume fraction显示文摘A method for packing irregular particles with a prescribed volume fraction is proposed.Furthermore,the generated granular material adheres to the prescribed statistical distribution and satisfies the desired complex spatial arrangement.First,the irregular geometries of the realistic particles were obtained from the original particle images.Second,the Minkowski sum was used to check the overlap between irregular particles and place an irregular particle in contact with other particles.Third,the optimised advance front method(OAFM)generated irregular particle packing with the prescribed statistical dis-tribution and volume fraction based on the Minkowski sum.Moreover,the signed distance function was introduced to pack the particles in accordance with the desired spatial arrangement.Finally,seven biaxial tests were performed using the UDEC software,which demonstrated the accuracy and potential usefulness of the proposed method.It can model granular material efficiently and reflect the meso-structural characteristics of complex granular materials.This method has a wide range of applications where discrete modelling of granular media is necessary. | Libing Du Xinrong Liu Yafeng Han Zhiyun Deng | 2023 | Journal of Rock Mechanics and Geotechnical Engineering2023，15，2： | 0 |
