| 1 | Generative API usage code recommendation with parameter concretization显示文摘Many programming languages and development frameworks have extensive libraries(e.g., JDK and Android libraries) that ease the task of software engineering if used effectively. With numerous library classes and sometimes intricate API(application programming interface) usage constraints, programmers often have difficulty remembering the library APIs and/or using them correctly. This study addresses this problem by developing an engine called DeepAPIRec, which automatically recommends the API usage code.Compared to the existing proposals, our approach distinguishes itself in two ways. First, it is based on a tree-based long short-term memory(LSTM) neural network inspired by recent developments in the machinelearning community. A tree-based LSTM neural network allows us to model and reason about variable-length,preceding and succeeding code contexts, and to make precise predictions. Second, we apply data-flow analysis to generate concrete parameters for the API usage code, which not only allows us to generate complete code recommendations but also improves the accuracy of the learning results according to the tree-based LSTM neural network. Our approach has been implemented for supporting Java programs. Our experimental studies on the JDK library show that at statement-level recommendations, DeepAPIRec can achieve a top-1 accuracy of about 37% and a top-5 accuracy of about 64%, which are significantly better than the existing approaches. Our user study further confirms that DeepAPIRec can help developers to complete a segment of code faster and more accurately as compared to IntelliJ IDEA. | Chi CHEN Xin PENG Jun SUN Zhenchang XING Xin WANG Yifan ZHAO Hairui ZHANG Wenyun ZHAO | 2019 | Science China(Information Sciences)2019，62，9： | 7 |

| 3 | Genetically-engineered“all-in-one”vaccine platform for cancer immunotherapy显示文摘An essential step for cancer vaccination is to break the immunosuppression and elicit a tumor-specific immunity.A major hurdle against cancer therapeutic vaccination is the insufficient immune stimulation of the cancer vaccines and lack of a safe and efficient adjuvant for human use.We discovered a novel cancer immunostimulant,trichosanthin(TCS),that is a clinically used protein drug in China,and developed a well-adaptable protein-engineering method for making recombinant protein vaccines by fusion of an antigenic peptide,TCS,and a cell-penetrating peptide(CPP),termed an'allin-one'vaccine,for transcutaneous cancer immunization.The TCS adjuvant effect on antigen presentation was investigated and the antitumor immunity of the vaccines was investigated using the different tumor models.The vaccines were prepared via a facile recombinant method.The vaccines induced the maturation of DCs that subsequently primed CD8^(+)T cells.The TCS-based immunostimulation was associated with the STING pathway.The general applicability of this genetic engineering strategy was demonstrated with various tumor antigens(i.e.,legumain and TRP2 antigenic peptides)and tumor models(i.e.,colon tumor and melanoma).These findings represent a useful protocol for developing cancer vaccines at low cost and time-saving,and demonstrates the adjuvant application of TCSdan old drug for a new application. | Aihua Wu Yingzhi Chen Hairui Wang Ya Chang Meng Zhang Pengfei Zhao Yisi Tang Qin Xu Zhuangzhi Zhu Yang Cao Yongzhuo Huang | 2021 | Acta Pharmaceutica Sinica B2021，11，11： | 1 |
| 4 | Anti-catalytic and zincophilic layers integrated zinc anode towards efficient aqueous batteries for ultra-long cycling stability显示文摘Aqueous zinc-based battery is usually plagued by serious dendrites and side reactions including Zn corrosion and water decomposition on the anode.To address the drawbacks,constructing coating layers with high conductivity and anti-catalytic effects on hydrogen evolution reaction has been considered as an efficient strategy.Herein,cheap and abundant twodimensional(2D)conductive graphite(KS-6)coating layer with high electronic conductivity(~106 S·m^(−1))could directly form strong bonding with Zn foil due to high zincophilicity,which correspondingly protects Zn metal from liquid electrolyte to inhibit parasitic hydrogen evolution and guide uniform Zn electrodeposition during cycling.The KS-6 layer owns a profitable charge redistribution effect to endow Zn anode with a lower nucleation energy barrier and a more uniformly distributed electric field compared with bare Zn.Therefore,such integrated Zn anode exhibits low voltage hysteresis(~38 mV)and excellent cycling stability with dendrite-free behaviors(1 mA·cm^(−2)and 2 mAh·cm^(−2))over 2,000 h,far outperforming many reported Zn metal anodes in aqueous systems.Encouragingly,in light of the superior Zn@KS-6 anode,VNOx powders and Prussian blue analogs Mn_(2)Fe(CN)_(6)are applied as the cathode materials to assemble full batteries,which show remarkable cycling stabilities and high Coulombic efficiencies(CEs)over 200 cycles with capacity retention of 81.5%for VNOx//Zn@KS-6 battery and over 400 cycles with capacity retention of 94.6%for Mn_(2)Fe(CN)_(6)//Zn@KS-6 battery,respectively. | Chunli Wang Yuxing Gao Lianshan Sun Yuan Zhao Dongming Yin Hairui Wang Jingchao Cao Yong Cheng Limin Wang | 2022 | Nano Research2022，15，9： | 1 |
| 5 | Bubble dynamics properties of B-particles in a quasi-2D gas-solid fluidized bed:Computational particle fluid dynamics numerical simulation and post-processed by digital image analysis technique显示文摘Bubble dynamics properties play a crucial and significant role in the design and optimization of gas-solid fluidized beds.In this study,the bubble dynamics properties of four B-particles were investigated in a quasi-two-dimensional(quasi-2D)fluidized bed,including bubble equivalent diameter,bubble size distribution,average bubble density,bubble aspect ratio,bubble hold-up,bed expansion ratio,bubble radial position,and bubble velocity.The studies were performed by computational particle fluid dynamics(CPFD)numerical simulation and post-processed with digital image analysis(DIA)technique,at superficial gas velocities ranging from 2u_(mf) to 7u_(mf).The simulated results shown that the CPFD simulation combining with DIA technique post-processing could be used as a reliable method for simulating bubble dynamics properties in quasi-2D gas-solid fluidized beds.However,it seemed not desirable for the simulation of bubble motion near the air distributor at higher superficial gas velocity from the simulated average bubble density distribution.The superficial gas velocity significantly affected the bubble equivalent diameter and evolution,while it had little influence on bubble size distribution and bubble aspect ratio distribution for the same particles.Both time-averaged bubble hold-up and bed expansion ratio increased with the increase of superficial gas velocity.Two core-annular flow structures could be found in the fluidized bed for all cases.The average bubble rising velocity increased with the increasing bubble equivalent diameter.For bubble lateral movement,the smaller bubbles might be more susceptible,and superficial gas velocity had a little influence on the absolute lateral velocity of bubbles.The simulated results presented a valuable and novel approach for studying bubble dynamics properties.The comprehensive understanding of bubble dynamics behaviors in quasi-2D gas-solid fluidized beds would provide support in the design,operation,and optimization of gas-solid fluidized bed reactors. | Zemin Yuan Zhong Huang Guotao Qin Guanjia Zhao Suxia Ma Hairui Yang Guangxi Yue | 2024 | Particuology2024，86，3： | 0 |
| 6 | Defective TiO_(2)hollow nanospheres as photo-electrocatalysts for photo-assisted Li-O_(2)batteries显示文摘The large overpotential for conventional Li-O_(2) batteries is an enormous challenge,which impedes their practical application.Here,we prepare a defective TiO_(2)(Ov-TiO_(2)) hollow nanosphere as photoelectrocatalyst for photo-assisted Li-O_(2) batteries to reduce the overpotential.Under illumination,the oxygen vacancies as a charge separation center contribute to the separation of electrons and holes.The generated electrons could promote reducing O_(2) to Li_(2)O_(2) during oxygen reduction reaction(ORR)process,while the generated holes are beneficial to Li_(2)O_(2) decomposition during oxygen evolution reaction(OER)process.Additionally,the proper concentration of oxygen vacancies will decrease the recombination rate between electrons and holes.The photo-assisted Li-O_(2) batteries with Ov-TiO_(2)-650 exhibit advanced performances,such as the low overpotential(0.70 V),the fine rate capability,and the considerable reversibility accompanied with the formation/decomposition of Li_(2)O_(2).We expect that these results could open a new mind to design of highly efficient photo-electrocatalysts for photo-assisted Li-O_(2) battery. | Hailiang Jiao Guiru Sun Yan Wang Zexu Zhang Zhao Wang Hairui Wang Haibo Li Ming Feng | 2022 | Chinese Chemical Letters2022，33，8： | 0 |
| 7 | Notch fatigue of Cu50Zr50 metallic glasses under cyclic loading:molecular dynamics simulations显示文摘Molecular dynamics simulation is performed to simulate the tension–compression fatigue of notched metallic glasses(MGs),and the notch effect of MGs is explored.The notches will accelerate the accumulation of shear transition zones,leading to faster shear banding around the notches’root causing it to undergo severe plastic deformation.Furthermore,a qualitative investigation of the notched MGs demonstrates that fatigue life gradually becomes shorter with the increase in sharpness until it reaches a critical scale.The fatigue performance of blunt notches is stronger than that of sharp notches.Making the notches blunter can improve the fatigue life of MGs. | Yong Yang Hairui Li Zailin Yang Jin Liu Evans Kabutey Kateye Jianwei Zhao | 2021 | Communications in Theoretical Physics2021，73，6： | 0 |
| 8 | Secrecy energy efficiency maximization for UAV-enabled multi-hop mobile relay system显示文摘To deal with the secrecy issues and energy efficiency issues in the unmanned aerial vehicles(UAVs) assisted communication systems, an UAV-enabled multi-hop mobile relay system is studied in an urban environment. Multiple rotary-wing UAVs with energy budget considerations are employed as relays to forward confidential information between two ground nodes in the presence of multiple passive eavesdroppers. The system secrecy energy efficiency(SEE), defined by the ratio of minimum achievable secrecy rate(SR) to total propulsion energy consumption(PEC), is maximized via jointly optimizing the trajectory and transmit power of each UAV relay. To solve the formulated non-convex fractional optimization problem subject to mobility, transmit power and information-causality constraints, an effective iterative algorithm is proposed by applying the updated-rate-assisted block coordinate decent method, successive convex approximation(SCA) technique and Dinkelbach method. Simulation results demonstrate the effectiveness of the proposed joint trajectory design and power control scheme. | Miao Jiansong Li Hairui Zheng Ziyuan Wang Chu Zhao Zhenmin | 2022 | The Journal of China Universities of Posts and Telecommunications2022，29，3： | 0 |
| 9 | Quantitative Parameters Analysis for Prenatally Echocardiographic Diagnosis of Atrioventricular Septal Defects显示文摘Background:Atrioventricular septal defects(AVSDs)are screened and diagnosed usually rely on the imaging characteristics of fetal echocardiography(FE).However,diagnosis on images is heavily depended on sonographers’experience and the quantitative data are rarely studied.Objective:This study aimed to realize the prenatal diagnosis of AVSDs by analyzing the quantitative data on FE.Methods:One hundred and thirteen cardiac quantitative data was analyzed in 370 normal and 49 AVSDs fetuses retrospectively.The top six with the highest diagnostic accuracy rate were acquired according to the area under the curve(AUC),and the diagnostic value of six variables was analyzed.Results:Six parameters obtained on the four-chamber view(4CHV),including the atrial to ventricular length ratio in end-diastole(AVLR-ED),AVLR-ED combined with the atrial to ventricular length ratio in end-systole(AVLR-ES),quantile score(Q score)of AVLR-ED,Q score of AVLR-ES,Q score of ventricle length in end-diastole(VL-ED),and AVLR-ES,were the top six with the highest diagnostic value,and the AUC was 0.99(95%CI 0.99–1.00),0.99(95%CI 0.99–1.00),0.99(95%CI 0.98–1.00),0.95(95%CI 0.91–0.99),0.93(95%CI 0.87–0.99),and 0.91(95%CI 0.83–1.00),respectively.And within the 20%false positive rate,the diagnostic sensitivity was greater than 100%,100%,100%,90%,90%,and 88%,respectively.Conclusions:Six variables could be used for prenatal diagnosis of AVSDs.Among them,AVLR-ED and Q score of AVLR-ED,obtained on the 4CHV,were more convenient to acquire and had higher diagnostic accuracy. | Xiaoxue Zhou Tingyang Yang Ye Zhang Yanping Ruan Jiancheng Han Xiaowei Liu Ying Zhao Xiaoyan Gu Tingting Liu Hairui Wang Yihua He | 2023 | Congenital Heart Disease2023，18，3： | 0 |
