| 1 | Dynamic Case Retrieval Method With Subjective Preferences and Objective Information for Emergency Decision Making显示文摘Case-based reasoning(CBR) is one of the best methods for generating an effective solution in an emergency. In recent years, some methods for generating emergency alternatives have been included in practical CBR applications, but there have been no in-depth studies of these processes. In this study,we propose a new method for dynamic case retrieval with subjective preferences and objective information, which considers the personal preferences of the decision makers and changes in the attributes of the emergency as the situation develops. First,we present a formula for calculating the case similarity and changing trends in the case considered, where similar cases are obtained. Next, we describe a method for measuring the overall assessment value with respect to similar historical cases, which is obtained by aggregating the case similarity, the utility case similarity, the first response time, and the implementation effect.The subjective preferences and objective information are also integrated in the decision-making process. Finally, we present a case study based on the emergency response to a fire in a highrise building, which illustrates the applicability and feasibility of the proposed method. | Jing Zheng Yingming Wang Shengqun Chen | 2018 | IEEE/CAA Journal of Automatica Sinica2018，5，3： | 7 |
| 2 | Feature Selection Method Based on Class Discriminative Degree for Intelligent Medical Diagnosis显示文摘By using efficient and timely medical diagnostic decision making,clinicians can positively impact the quality and cost of medical care.However,the high similarity of clinical manifestations between diseases and the limitation of clinicians’knowledge both bring much difficulty to decision making in diagnosis.Therefore,building a decision support system that can assist medical staff in diagnosing and treating diseases has lately received growing attentions in the medical domain.In this paper,we employ a multi-label classification framework to classify the Chinese electronic medical records to establish corresponding relation between the medical records and disease categories,and compare this method with the traditional medical expert system to verify the performance.To select the best subset of patient features,we propose a feature selection method based on the composition and distribution of symptoms in electronic medical records and compare it with the traditional feature selection methods such as chi-square test.We evaluate the feature selection methods and diagnostic models from two aspects,false negative rate(FNR)and accuracy.Extensive experiments have conducted on a real-world Chinese electronic medical record database.The evaluation results demonstrate that our proposed feature selection method can improve the accuracy and reduce the FNR compare to the traditional feature selection methods,and the multi-label classification framework have better accuracy and lower FNR than the traditional expert system. | Shengqun Fang Zhiping Cai Wencheng Sun Anfeng Liu Fang Liu Zhiyao Liang Guoyan Wang | 2018 | Computers, Materials & Continua2018，，6： | 5 |

| 4 | Analysis of the efficacy of transcatheter arterial infusion chemotherapy in the treatment of pancreatic carcinoma显示文摘Objective:To evaluate the clinical efficacy of infusion of gemcitabine(GEM) and fluorouracil(5-FU)through the celiac artery and superior mesenteric artery in the treatment of pancreatic carcinoma(PC).Methods:We analyzed 20 patients diagnosed clinically or pathologically with PC,without metastases,who had an estimated survival duration of>3 months in our department from May 2009 to December 2014.Nine patients were treated directly without surgical resection of the tumor,while the other 11 patients were treated after surgery.In all patients,the femoral artery was punctured using the Seldinger technique,and a catheter was placed in the opening of the celiac artery or the superior mesenteric artery.We administered 500 mg/m2 GEM and 500 mg/m2 5-FU.Observational data included data on clinical efficacy and survival rates during the follow-up period of 3-72 months.Results:Twenty patients were treated 85 times with transcatheter arterial infusion chemotherapy(TAI).The survival rates were 80%,40%,35%,20%,10%,and 5% at 3,6,12,24,and 72 months,respectively.Conclusion: TAI chemotherapy with GEM and 5-FU may be a therapeutic option for the treatment of PC. | Chunhui Nie Yuelin Zhang Guanhui Zhou Tanyang Zhou Tongyin Zhu Baoquan Wang Shengqun Chen Hongliang Wang Ziniu Yu Li Jing Junhui Sun | 2021 | Journal of Interventional Medicine2021，4，1： | 4 |
| 5 | Host cell Rac1 GTPase facilitates Toxoplasma gondii invasion显示文摘Dear Editor,Toxoplasma gondii is broadly distributed worldwide,and infects nearly all warm-blooded animals(Montoya and Liesenfeld,2004).Its primary infections in pregnant women may lead to abortion,stillbirth and other conditions,and it also attributes largely to encephalitis,retinochoroiditis and other serious diseases in immunocompromised individuals(Moncada and Montoya,2012).Rac1 is a small GTPase in the Rho family that plays an important role in cytoskeleton reorganization(Hall,1998).Rac1 GTPase is reported to be activated by infection of Chlamydia pneumoniae(Zhang et al.,2014). | Haixia Wei Lijuan Zhou Shuizhen Wu Dongliang Li Shengqun Deng Hongjuan Peng | 2020 | Science China(Life Sciences)2020，63，4： | 2 |
| 6 | Codes cross-correlation analysis and data/pilot code pairs optimization for Galileo E1 OS and GPS L1C显示文摘The Galileo E1 open service (OS) and the global positioning system (GPS) L1C are intending to use the multiplexed binary offset carrier (MBOC) modulation in E1/L1 band, including both pilot and data components. The impact of data and pilot codes cross-correlation on the distortion of the discriminator function (i.e., the S-curve) is investigated, when only the pilot (or data) components of MBOC signals are tracked. It is shown that the modulation schemes and the receiver configuration (e.g., the correlator spacing) strongly affect the S-curve bias. In this paper, two methods are proposed to optimize the data/pilot code pairs of Galileo E1 OS and GPS L1C. The optimization goal is to obtain the minimum average S-curve bias when tracking only the pilot components a the specific correlator spacing. Figures of merit, such as S-curve bias, correlation loss and code tracking variance have been adopted for analyzing and comparing the un-optimized and optimized code pairs. Simulation results show that the optimized data/pilot code pairs could significantly mitigate the intra-channel codes cross-correlation, and then improve the code tracking performance of MBOC signals. | Yang Zaixiu Huang Zhigang Geng Shengqun | 2013 | Chinese Journal of Aeronautics2013，26，3： | 2 |
| 7 | Strain enhancement for a MoS2-on-GaN photodetector with an Al2O3 stress liner grown by atomic layer deposition显示文摘Strain regulation as an effective way to enhance the photoelectric properties of two dimensional(2D)transition metal dichalcogenides has been widely employed to improve the performance of photovoltaic devices.In this work,tensile strain was introduced in multilayer MoS2 grown on GaN by depositing 3 nm of Al2O3 on the surface.The temperature dependent Raman spectrum shows that the thermal stability of MoS2 is improved by Al2O3.Theoretical simulations confirmed the existence of tensile strain on MoS2 covered with Al2O3,and the bandgap and electron effective mass of six layers of MoS2 decreased due to tensile strain,which resulted in an increase of electron mobility.Due to the tensile strain ffect,the photodetector with the Al2O3 stress liner achieved better performance under the illumination of 365 nm wavelength,including a higher responsivity of 24.6 A/W,photoconductive gain of 520,and external quantum fficiency of 8381%,which are more than twice the corresponding values of photodetectors without Al2O3.Our work provides an effective technical way for improving the performance of 2D material photodetectors. | ZHIWEN LI JIANGLIU LUO SHENGQUN HU QIANG LIU WENJIE Yu YOUMING LU XINKE LIU | 2020 | Photonics Research2020，8，6： | 1 |

| 12 | TURBO AIDED CYCLIC PREFIX RECONSTRUCTION FOR CODED SINGLE-CARRIER SYSTEMS WITH FREQUENCY-DOMAIN EQUALIZATION (SC-FDE)显示文摘In this paper, a Turbo aided Cyclic Prefix (CP) reconstruction scheme, termed Turbo- CPR, is proposed for Single-Carrier systems with Frequency-Domain Equalization (SC-FDE) that employ insufficient CP in the transmitter. In Turbo-CPR, the decoder output is incorporated in the process of equalization, i.e. Turbo equalizer is employed. It is shown in the simulation results that Turbo-CPR not only recovers the performance loss due to insufficiency of CP, but also provides extra gains over the lower bound of performance for conventional CP reconstruction schemes. | Wei Shengqun Wu Qihui Wang Jinlong | 2007 | Journal of Electronics(China)2007，24，6： | 1 |

| 15 | Some Generalized Single Valued Neutrosophic Linguistic Operators and Their Application to Multiple Attribute Group Decision Making显示文摘This paper proposes a group decision making method based on entropy of neutrosophic linguistic sets and generalized single valued neutrosophic linguistic operators. This method is applied to solve the multiple attribute group decision making problems under single valued neutrosophic liguistic environment, in which the attribute weights are completely unknown. First, the attribute weights are obtained by using the entropy of neutrosophic linguistic sets. Then three generalized single valued neutrosophic linguistic operators are introduced, including the generalized single valued neutrosophic linguistic weighted averaging(GSVNLWA) operator, the generalized single valued neutrosophic linguistic ordered weighted averaging(GSVNLOWA) operator and the generalized single valued neutrosophic linguistic hybrid averaging(GSVNLHA) operator, and the GSVNLWA and GSVNLHA operators are used to aggregate information. Furthermore, similarity measure based on single valued neutrosophic linguistic numbers is defined and used to sort the alternatives and obtain the best alternative. Finally,an illustrative example is given to demonstrate the feasibility and effectiveness of the developed method. | Ruipu TAN Wende ZHANG Shengqun CHEN | 2017 | Journal of Systems Science and Information2017，8，2： | 1 |

| 17 | A Method of Emergency Volunteer Team Internal Participation in Rescue Decision-Making Considering Psychological Behavior显示文摘A method for internal participation in rescue decision-making of emergency volunteer teams considering psychological behavior is proposed to address the time sequence of rescue tasks.Firstly,the problem of multi-tasking and multi-operation within the emergency volunteer team is described.Secondly,considering that task leaders are influenced by behavioral and psychological factors in the evaluation,the required time for the job is used as a reference point,and the expected time that volunteers can complete the job is used as an attribute value.The task leader's prospect satisfaction value for each volunteer is calculated based on prospect theory,and the perceived utility values of disappointment theory and regret theory are calculated to measure the task leader's satisfaction with each volunteer.Furthermore,a multilayer coded genetic algorithm is used to construct an optimization model for emergency volunteer decision-making with the objective of maximizing the satisfaction value.Finally,the feasibility and effectiveness of this method are illustrated by an example analysis.The result shows that the efficiency of rescue tasks can be improved through decision optimization within the volunteer team. | Jie BAI Shengqun CHEN | 2024 | Journal of Systems Science and Information2024，12，1： | 0 |

| 19 | Volunteer rescue dispatch during the Coronavirus Disease 2019 epidemic:Using the recruitment of volunteers for pneumonia epidemic prevention and control in Chun’an County as an example显示文摘To solve the problem of volunteer dispatch during the Coronavirus Disease 2019(COVID-19)epidemic,a many-to-many two-sided matching volunteer dispatch method based on an improved predator-search algorithm is pro-posed.First,different evaluation index sets for volunteers and rescue tasks were developed,and weightings were determined using the analytic hierarchy process.Subsequently,the actual and expected values of the different indicators of the two parties were determined,and the triangular fuzzy number was used to calculate the satis-faction of the two parties.Based on this number,we used a linear weighting method to calculate the combined satisfaction and build a many-to-many two-sided matching model according to the demands of both parties.Sub-sequently,an improved predator-search algorithm was used to solve the model.Finally,taking the recruitment of volunteers for pneumonia epidemic prevention and control in Chun’an County as an example,the method proposed in our study was verified.A comparison and analysis of the results further demonstrated the feasibility and advantages of this method. | Liting Chen Shengqun Chen Jing Zheng Jianqing Gao | 2022 | Journal of Safety Science and Resilience2022，3，4： | 0 |
| 20 | Towards a Smallest Scale of Context in Ontology Integration显示文摘In order to solve the ambiguity problems in the seman-tic context (structure, granularity or scale) emerging in the process of ontology integration application, this paper analyzes the essen-tial characters of context structure, proposes a novel semantic context generating algorithm, which is implemented over VO-Editor(visual ontology editor), from the satisfiability-based point of view, and proves that the context entity generated by this algorithm is smallest in scale and unique. It offers a feasible means for developers to handle context problems for ontology integration application. | XIAO Ruliang TANG Shengqun | 2008 | Wuhan University Journal of Natural Sciences2008，13，4： | 0 |
