| 1 | A strategy for service realization in service-oriented design显示文摘Recently service orientation is becoming a mainstream approach for building large scale software systems. A key requirement in service-oriented design is the de- pendability of service. It stipulates that the behavior of services is controllable. Formal models can aid in constructing software in a dependable manner. They can describe ser- vices precisely and compose them together consistently. This paper presents a strategy for service realization based on a novel layered formal model. When a service is provided or required via internet, the semantic consistency becomes critical issue. Our architecture tackles the issue by proposing a novel scheme: defining contract of a service to keep semantic information. Although service-oriented design is our prime target, the contract models, to a large extent, are independent of the framework of design and therefore ap- plicable to large scale software design in general. | LIU Jing HE Jifeng LIU Zhiming | 2006 | Science in China(Series F)2006，49，6： | 4 |

| 3 | Oscillating Cellulase Adsorption and Enhanced Lignocellulose Hydrolysis upon Ultrasound Treatment显示文摘We investigated the effects of ultrasound treatment on cellulase adsorption and lignocellulose hydrolysis.The activity of cellulase remained constant upon lowpower ultrasound treatment(<120 W) and decreased using high-power ultrasound(>280 W).Oscillating cellulase adsorption occurred upon ultrasound treatment with any intensity.The maxima for desorption and adsorption were41.9 and 83.1%,respectively,during 1 h of 90 W ultrasound treatment at 50 °C.A comparison between the shorttime with long-time ultrasound experiments indicated that ultrasound treatment tended to desorb cellulase from substrate.However,ultrasound treatment also led to further surface erosion of biomass,which increased cellulase accessibility.These joint actions of ultrasound treatment induced the oscillating adsorption of cellulase.The increase in cellulase accessibility caused by ultrasound treatment led to a significant enhancement in lignocellulose hydrolysis. | Rongxin Su Renjun Yang Yang Jifeng Ruoyu Du Renliang Huang Wei Qi Zhimin He | 2017 | Transactions of Tianjin University2017，23，1： | 3 |
| 4 | Predicting wheat kernels’protein content by near infrared hyperspectral imaging显示文摘The objective of this study was to explore the potential of near infrared hyperspectral imaging combined with statistical regression models and neural networks for nondestructive prediction of protein content of wheat kernels.Seventy-nine samples from 11 breeds of wheat kernels were collected.The protein percentage of each sample measured by semimicro-Kjeldahl method was taken as the reference value.After comparing the prediction models of principal components regression(PCR)and partial least squares regression(PLSR)with various pretreatment methods,PLSR preprocessed by zero mean normalization(z score)function of MATLAB was found to obtain better prediction results than other regression models.Based on 10 latent variables of PLSR,the radial basis function(RBF)neural network was applied to improve the prediction,in which the coefficients of determination(R2)were greater than 0.92 for both the calibration set and validation set,while the corresponding RMSE values were 0.3496 and 0.4005,respectively.Therefore,hyperspectral imaging can provide a fast and non-destructive method for predicting the wheat kernels’protein content. | Yang Shuqin He Dongjian Ning Jifeng | 2016 | International Journal of Agricultural and Biological Engineering2016，9，2： | 2 |
| 5 | RNA-Seq Study Reveals AP2-Domain-Containing Signalling Regulators Involved in Initial Imbibition of Seed Germination in Rice显示文摘A number of internal signals are required for seed germination.However,the precise signalling responses in the initial imbibition of seed germination are not yet fully understood in rice.In this study,the RNA sequencing(RNA-Seq)approach was conducted in 8 h imbibed seeds to understand the signalling responses in the initial imbibition of rice seed germination.A total of 563 differentially expressed genes(DEGs)with at least 4-fold change were identified in 8 h imbibed seeds compared to dry seeds.MapMan analysis revealed that the majority of signalling response-related DEGs were hormone-and transcription factor-related genes,in which the largest number of DEGs belong to the AP2-domain-containing regulators,and their expressions were significantly induced in the initial imbibition of seed germination in rice.Moreover,at least five AP2-domain-containing transcription factor OsDREBs were identified in the initial imbibition of rice seed germination,and the expressions of 251 DEGs were putatively regulated by OsDREBs through the dehydration-responsive element(DRE)cis-element assay.It suggested that the OsDREBs might play important roles in the regulation of initial seed imbibition in rice.The identified genes provide a valuable resource to study the signalling regulation of seed germination in the future. | HE Yongqi ZHAO Jia FENG Defeng HUANG Zhibo LIANG Jiaming ZHENG Yufei CHENG Jinping YING Jifeng WANG Zhoufei | 2020 | Rice science2020，27，4： | 2 |

| 10 | Convergence and optimality of BS-type discrete hedging strategy under stochastic interest rate显示文摘We focus on the asymptotic convergence behavior of the hedging errors of European stock option due to discrete hedging under stochastic interest rates. There are two kinds of BS-type discrete hedging differ in hedging instruments: one is the portfolio of underlying stock, zero coupon bond, and the money market account (Strategy BSI); the other is the underlying stock, zero coupon bond (Strategy BSII). Similar to the results of the deterministic interest rate case, we show that convergence speed of the discounted hedging errors is 1/2-order of trading frequency for both strategies. Then, we prove each of the BS-type strategy is not only locally optimal, but also globally optimal under the corresponding measure. Finally, we give some numerical examples to illustrate the results. All the discussion is based on non-arbitrage condition and zero transaction cost. | HE JiFeng WU Lan | 2011 | Science China Mathematics2011，54，7： | 1 |

| 15 | The relationship between treatment-induced hypertension and efficacy of anlotinib in recurrent or metastatic esophageal squamous cell carcinoma显示文摘Objective:In this post-hoc analysis,we evaluated anlotinib treatment-induced hypertension as a potential predictive factor of efficacy in esophageal squamous cell carcinoma(ESCC)patients.Methods:A total of 109 patients enrolled in the anlotinib group in a phase 2 trial were included.The tumor response was assessed by computed tomography at week 3,week 6,and then every 6 weeks until progressive disease was observed.The primary endpoint of the study was progression free survival(PFS).The secondary endpoints included overall survival(OS)and objective response rate(ORR).Results:In all patients,the median PFS was 3.02 months[95%confidence interval(CI):2.63–3.65 months]and the OS was 6.11 months(95%CI:4.40–7.79 months).The ORR was 7.34%(95%CI:3.22%–13.95%).A total of 59(54%)patients were diagnosed with treatment-induced hypertension(Group A),and the remaining patients(n=50,46%)were in Group B.Baseline prognostic factors were similar between the 2 groups.Patients in Group A had a longer PFS and OS and higher ORR.When stratifying patients using a previously known history of hypertension,treatment-induced hypertension was a predictor only for patients without previous hypertension,who had longer PFS[hazard ratio(HR):0.40,95%CI:0.24–0.68]and OS(HR:0.37,95%CI:0.21–0.67).Conclusions:We showed,for the first time,a correlation between treatment-induced hypertension and better prognoses in recurrent or metastatic ESCC patients treated with anlotinib,without a previously known history of hypertension.Treatment-induced hypertension may be a simple and low cost predictor for anlotinib antitumor efficacy in these patients,which may also reflect the intended target inhibition. | Yan Song Juxiang Xiao Wentao Fang Ping Lu Qingxia Fan Yongqian Shu Jifeng Feng Shu Zhang Yi Ba Yang Zhao Ying Liu Chunmei Bai Yuxian Bai Yong Tang Jie He Jing Huang | 2021 | Cancer Biology & Medicine2021，18，2： | 1 |
| 16 | AADL+: a simulation-based methodology for cyber-physical systems显示文摘AADL (architecture analysis and design language) concentrates on the modeling and analysis of application system architectures.It is quite popular for its simple syntax,powerful functionality and extensibility and has been widely applied in embedded systems for its advantage.However,it is not enough for AADL to model cyber-physical systems (CPS) mainly because it cannot be used to model the continuous dynamic behaviors.This paper proposes an approach to construct a new sublanguage of AADL called AADL+,to facilitate the modeling of not only the discrete and continuous behavior of CPS,but also interaction between cyber components and physical components.The syntax and semantics of the sublanguage are provided to describe the behaviors of the systems.What's more,we develop a plug-in to OSATE (open-source AADL tool environment) for the modeling of CPS.And the plug-in supports syntax checking and simulation of the system model through linking with modelica.Finally,the AADL+ annex is successfully applied to model a lunar rover control system. | Jing LIU Tengfei LI Zuohua DING Yuqing QIAN Haiying SUN Jifeng HE | 2019 | Frontiers of Computer Science2019，13，3： | 1 |
| 17 | Multiplexed imaging of tumor immune microenvironmental markers in locally advanced or metastatic non-small-cell lung cancer characterizes the features of response to PD-1 blockade plus chemotherapy显示文摘Background:Although programmed cell death 1(PD-1)blockade plus chemotherapy can significantly prolong the progression-free survival(PFS)and overall survival(OS)in first-line settings in patients with driver-negative advanced non-small-cell lung cancer(NSCLC),the predictive biomarkers remain undetermined.Here,we investigated the predictive value of tumor immune microenvironmental marker expression to characterize the response features to PD-1 blockade plus chemotherapy.Methods:Tumor tissue samples at baseline were prospectively collected from 144 locally advanced or metastatic NSCLC patients without driver gene alterations who received camrelizumab plus chemotherapy or chemotherapy alone.Tumor immune microenvironmental markers,including PD-1 ligand(PDL1),CD8,CD68,CD4 and forkhead box P3,were assessed using multiplex immunofluorescence(mIF)assays.Kaplan-Meier curveswere used to determine treatment outcome differences according to their expression status.Mutational profiles were compared between tumors with distinct expression levels of these markers and their combinations.Results:Responders had significantly higher CD8/PD-L1(P=0.015)or CD68/PD-L1 co-expression levels(P=0.021)than non-responders in the camrelizumab plus chemotherapy group,while no difference was observed in the chemotherapy group.Patients with high CD8/PD-L1 or CD68/PD-L1 co-expression level was associated with significantly longer PFS(P=0.002,P=0.024;respectively)and OS(P=0.006,P=0.026;respectively)than those with low co-expression in camrelizumab plus chemotherapy group.When comparing survival in the camrelizumab plus chemotherapy with chemotherapy by CD8/PD-L1 co-expression stratification,significantly better PFS(P=0.003)and OS(P=0.032)were observed in high co-expression subgroups.The predictive value of CD8/PD-L1 and CD68/PD-L1 co-expression remained statistically significant for PFS and OS when adjusting clinicopathological features.Although the prevalence of TP53 or KRAS mutations was similar between patients with and without CD8/PD-L1 or CD68/PD-L1 co-expression,the positive groups had a significantly higher proportion of TP53/KRAS co-mutations than the negative groups(both 13.0%vs.0.0%,P=0.023).Notably,enriched PI3K(P=0.012)and cell cycle pathway(P=0.021)were found in the CD8/PD-L1 co-expression group.Conclusion:Tumor immune microenvironmental marker expression,especially CD8/PD-L1 or CD68/PD-L1 co-expression,was associated with the efficacy of PD-1 blockade plus chemotherapy as first-line treatment in patients with advanced NSCLC. | Fengying Wu Tao Jiang Gongyan Chen Yunchao Huang Jianying Zhou Lizhu Lin Jifeng Feng Zhehai Wang Yongqian Shu Jianhua Shi Yi Hu Qiming Wang Ying Cheng Jianhua Chen Xiaoyan Lin Yongsheng Wang Jianan Huang Jiuwei Cui Lejie Cao Yunpeng Liu Yiping Zhang Yueyin Pan Jun Zhao LiPing Wang Jianhua Chang Qun Chen Xiubao Ren Wei Zhang Yun Fan Zhiyong He Jian Fang Kangsheng Gu Xiaorong Dong Tao Zhang Wei Shi Jianjun Zou Xuejuan Bai Shengxiang Ren Caicun Zhou | 2022 | Cancer Communications2022，42，12： | 1 |

| 19 | Developer recommendation on bug commenting:a ranking approach for the developer crowd显示文摘A bug tracking system provides a collaborative platform for the developer crowd. After a bug report is submitted, developers can make comments to supplement the details of the bug report. Due to the large number of developers and bug reports, it is hard to determine which developer(also called commenter) is able to comment on a particular bug report. We refer to the problem of recommending developers for commenting on bug reports as commenter recommendation. In this paper, we perform an empirical analysis on commenter recommendation based on five-year bug reports of four open source projects. First, we preliminarily analyze bug comments and commenters in three categories, the relationship between commenters and fixers, the data scale of comments, and the collaboration on bug commenting. Second, we design a recommendation approach via ranking developers in the crowd to reduce the manual effort of identifying commenters. In this approach,we formulize the commenter recommendation problem as a multi-label recommendation task and leverage both developer collaboration and bug content to find out appropriate commenters. Experimental results show that our approach can effectively recommend commenters; 41% to 75% of the recall value is achieved for top-10 recommendation. Our empirical analysis on bug commenting can help developers understand and improve the process of fixing bugs. | Jifeng XUAN He JIANG Hongyu ZHANG Zhilei REN | 2017 | Science China(Information Sciences)2017，60，7： | 1 |
