1A Text Similarity Measurement Based on Semantic Fingerprint of Characteristic Phrases显示文摘Text similarity measurements are the basis for measuring the degree of matching between two or more texts. Traditional large-scale similarity detection methods based on a digital fingerprint have the advantage of high detection speed, which are only suitable for accurate detection. We propose a method of Chinese text similarity measurement based on feature phrase semantics.Natural language processing(NLP) technology is used to pre-process text and extract the keywords by the Term frequency-Inverse document frequency(TF-IDF) model and further screen out the feature words. We get the exact meaning of a word and semantic similarities between words and a How Net semantic dictionary. We substitute concepts to get the feature phrases and generate a semantic fingerprint and calculate similarity. The experimental results indicate that the method proposed is superior in similarity detection in terms of its accuracy rate,recall rate, and F-value to the traditional and digital fingerprinting method.PANG Shanchen YAO Jiamin LIU Ting ZHAO Hua CHEN Hongqi 2020Chinese Journal of Electronics2020,29,2:3

4Fault Diagnosis for Service Composition by Spiking Neural P Systems with Colored Spikes显示文摘A variety of web services have emerged with the rapid development of the Internet. These services are often of a single function. The value-added services can be achieved by combing with multiple services. The processing speed and stability of existing methods in service composition were not very well and seldom consider the fault diagnosis and handling methods for the service, which results in a greater probability of the service composition failure at run time. We use spiking neural P systems with colored spikes to model the fault of available service, component, and connector in the service composition. The proposed model can be used to locate a fault and handle it correctly when the service combination fails, the advantage of efficiency and stability of proposed method has been proved by comparing with the method of Petri net.PANG Shanchen WANG Min QIAO Sibo WANG Xun CHEN Hongqi 2019Chinese Journal of Electronics2019,28,5:2

7Online Video Popularity Regression Prediction Model with Multichannel Dynamic Scheduling Based on User Behavior显示文摘Popularity prediction of online video is widely used in many different scenarios.It can not only help video service providers to schedule video web sites,but also bring considerable profits on investment for both providers and advertisers if popularity of online video is predicted accurately.However,online video popularity prediction still cannot have a satisfactory result,due to the complexity of many crucial factors especially of video distribution network.In this article,we extract seven factors from huge amounts of data about user behavior,establishing a new multiple linear regression model to initially predict online video popularity.After that,a multichannel video popularity dynamic scheduling model is proposed to schedule videos on which channel and what time to be broadcast,according to its popularity predicted by multiple linear regression model,ensuring that maximum the sum value of online video popularity of each channel.Experimental results on dataset obtained from Sohu Video,a video service provider in China,and real-world video flow in Sohu Video demonstrate that the proposed model is robust and has promising performance in predicting online video popularity,which is helpful for video service providers to schedule videos on web sites effectively in the future.QIAO Sibo PANG Shanchen WANG Min ZHAI Xue DAI Feng 2021Chinese Journal of Electronics2021,30,5:1

14AMTS:Adaptive Multi-Objective Task Scheduling Strategy in Cloud Computing显示文摘Task scheduling in cloud computing environments is a multi-objective optimization problem, which is NP hard. It is also a challenging problem to find an appropriate trade-off among resource utilization, energy consumption and Quality of Service(QoS) requirements under the changing environment and diverse tasks. Considering both processing time and transmission time, a PSO-based Adaptive Multi-objective Task Scheduling(AMTS) Strategy is proposed in this paper. First, the task scheduling problem is formulated. Then, a task scheduling policy is advanced to get the optimal resource utilization, task completion time, average cost and average energy consumption. In order to maintain the particle diversity, the adaptive acceleration coefficient is adopted. Experimental results show that the improved PSO algorithm can obtain quasi-optimal solutions for the cloud task scheduling problem.HE Hua XU Guangquan PANG Shanchen ZHAO Zenghua 2016China Communications2016,13,4:0

16Flexible PEDOT:PSS nanopapers as“anion-cation regulation”synergistic interlayers enabling ultra-stable aqueous zinc-iodine batteries显示文摘Aqueous zinc-iodine(Zn-I_(2))batteries are promising candidates for low-cost grid-scale energy storage systems.However,the long-term stability and energy density of the Zn-I_(2)batteries are largely hindered by the lack of feasible and scalable methods that coherently suppress polyiodide shuttling and Zn dendrites growth,especially at high current densities.Herein,a flexible,thin and lightweight poly(3,4-ethy lenedioxythiophene):polystyrene sulfonate(PEDOT:PSS)nanopaper is designed as an“anion-cation regulation”synergistic interlayer to tackle the above issues.The PEDOT:PSS interlayer exhibits a 3D nanofibrous network with uniformly distributed mesopores,abundant polar groups and intrinsic conductivity,which renders an even Zn^(2+)flux at Zn anode and facilitates homogeneous current distributions at I_(2)cathode.Meanwhile,such interlayer can act as physiochemical shield to enhance the utilization of I_(2)cathode via the coulombic repulsion and chemical adsorption effect against polyiodide shuttling.Thus,long-term dendrite-free Zn plating/stripping is achieved at simultaneous high current density and high areal capacity(550 h at 10 m A cm^(-2)/5 m Ah cm^(-2)).Zn-I_(2)batteries harvest a high capacity(230 m Ah g^(-1)at 0.1 A g^(-1))and an ultralong lifespan(>20000 cycles)even at 10 A g^(-1).This work demonstrates the potential use of the multifunctional interlayers for Zn-I_(2)battery configuration innovation by synergistic regulation of cations and anions at the electrodes/electrolyte interface.Ying Zhang Tianyu Zhao Shanchen Yang Yaxin Zhang Yue Ma Zhaohui Wang 2022Journal of Energy Chemistry2022,,12:0
17Fracture behavior dependent on crack-tip shapes in nanoscale crack-defect monolayer boron nitride sheets显示文摘Nanoscale defects,including cracks,circular holes,and the triangular-shaped defects,often occur in the growth of boron nitride nanosheets(BNNS).In this study,the fracture behavior of chiral BNNS with different crack-tip shapes and the interactions of nanoscale crack-defects are studied using molecular dynamics(MD)simulations and finite element(FE)analysis.Both MD and FE results indicate that the fracture strength of BNNS with two crack tips(t=2)is significantly higher than that with one crack tip(t=1),in which the difference in zigzag(ZZ)direction is more obvious than that in armchair(AC)direction,mainly due to the fact that the change of bond angles near the crack tips is more substantial in the ZZ direction than those in the AC direction.Our results show that the fracture strength of BNNS strongly depends on crack-tip shapes,chiral angles,the defect-to-crack tip spacing and deflection angles.Checking against the current MD simulations and FE analysis shows the present results are reasonable.This study should be of great importance for enhancing the fracture performance of BNNS by modulating their crack-tip shapes and the interactions of nanoscale crack-defects.Wentao Su Chunhua Zhu Anping Hua Shanchen Li Junhua Zhao 2021International Journal of Smart and Nano Materials2021,12,1:0
18Identification of genes responsive to apoptosis in HL-60 cells显示文摘AIM: To identify genes responsive to apoptosis in HL-60 cells treated by homoharringtonine. METHODS: cDNA microarray technology was used to detect gene expression and the result of microarrays for genes (TIEG and VDUP1) was confirmed by Northern analysis. RESULTS: Seventy-five individual mRNAs whose mass changed significantly were identified. Among these genes (25 were up-regulated and 50 were down-regulated), most are known related to oncogenes and tumor suppressor. Some genes were involved in apoptosis signaling pathways. CONCLUSION: TGFβ and TNF apoptosis signaling pathways were initiated during apoptosis in HL-60 cells. TIEG and VDUP1 play important roles in mediating apoptosis.WeiJIN Le-fengQU PingMIN ShanCHEN HongLI HeLU Yong-taiHOU 2004Acta Pharmacologica Sinica2004,25,3:0
