2Topic enhanced deep structured semantic models for knowledge base question answering显示文摘Knowledge Base Question Answering(KBQA) is a hot research topic in natural language processing(NLP). The most challenging problem in KBQA is how to understand the semantic information of natural language questions and how to bridge the semantic gap between the natural language questions and the structured fact triples in knowledge base. This paper focuses on simple questions which can be answered by a single fact triple in knowledge base. We propose a topic enhanced deep structured semantic model for KBQA. The proposed method considers the task of KBQA as a matching problem between questions and the subjects and predicates in knowledge base. And the proposed model consists of two stages to match the subjects and predicates, respectively. In the first stage, we propose a Convolutional based Topic Entity Extraction Model(CTEEM) to extract topic entities mentioned in questions. With the extracted entities, we can retrieve the relevant candidate fact triples from knowledge base and obviously decrease the amount of noising candidates. In the second stage, we employ Deep Structured Semantic Models(DSSMs) to compute the semantic relevant score between questions and predicates in the candidates. And we combine the semantic level and the lexical level scores to rank the candidates. We evaluate the proposed method on KBQA dataset released by NLPCC-ICCPOL 2016. The experimental results show that our proposed method achieves the third place among the 21 submitted systems.Furthermore, we also extend the DSSM by using Bi LSTM and integrate a convolutional structure on the top of Bi LSTM layers. Our experimental results show that the extension models can further improve the performance.Zhiwen XIE Zhao ZENG Guangyou ZHOU Weijun WANG 2017Science China(Information Sciences)2017,60,11:10

6Computer-aided ionic liquid design for alkane/cycloalkane extractive distillation process显示文摘A computer-aided ionic liquid design(CAILD) study is presented for the frequently encountered alkane/cycloalkane separations in petrochemical industry. Exhaustive experimental data are first collected to extend the UNIFAC-IL model for this system, where the proximity effect in alkanes and cycloalkanes is considered specifically by defining distinct groups. The thermodynamic performances of a large number of ILs for 4 different alkane/cycloalkane systems are then compared to select a representative example of such separations. By applying n-heptane/methylcyclohexane extractive distillation as a case study, the CAILD task is cast as a mixed-integer nonlinear programming(MINLP) problem based on the obtained task-specific UNIFAC-IL model and two semi-empirical models for IL physical properties. The top 5 IL candidates determined by solving the MINLP problem are subsequently introduced into Aspen Plus for process simulation and economic analysis, which finally identify 1-hexadecyl-methylpiperidinium tricyanomethane([C_(16)MPip][C(CN)_3]) as the best entrainer for this separation.Zhen Song Xinxin Li He Chao Fan Mo Teng Zhou Hongye Cheng Lifang Chen Zhiwen Qi 2019Green Energy & Environment2019,4,2:6

8Metallothionein expression induced by nickel accumulation in the midgut of Spodoptera litura Fabricius larvae exposed to nickel显示文摘Metallothionein expression induced by nickel accumulation in the midgut of Spodoptera litura Fabri- cius larvae was investigated by exposing S. litura larvae to the artificial diets amended with different doses of nickel for 3 generations. Nickel accumulations in the midgut of 6th instar larvae were detected by Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES), and the induced metal- lothionein expression in the midgut of 5th and 6th instar larvae in 120 h were quantified using cad- mium-hemoglobin total saturation methods. The accumulated nickel in the midgut of the 6th instar larvae within a generation increased with the increase of the nickel doses in the treated diets and showed significant dose-dependence with the nickel doses in diets. Metallothioneins induced by nickel accumulated in the larval midgut also increased with nickel doses in diets and with the increasing stressing time in a generation. Results also suggested that the metallothionein expression was differ- ent with the time of S. litura larvae stressed by nickel.SUN HongXia ZHOU Qiang TANG WenCheng SHU YingHua ZOU ZhiWen ZHANG GuRent 2007Chinese Science Bulletin2007,52,23:4
9Progress in octahedral spherical hohlraum study显示文摘In this paper,we give a review of our theoretical and experimental progress in octahedral spherical hohlraum study.From our theoretical study,the octahedral spherical hohlraums with 6 Laser Entrance Holes(LEHs)of octahedral symmetry have robust high symmetry during the capsule implosion at hohlraum-to-capsule radius ratio larger than 3.7.In addition,the octahedral spherical hohlraums also have potential superiority on low backscattering without supplementary technology.We studied the laser arrangement and constraints of the octahedral spherical hohlraums,and gave a design on the laser arrangement for ignition octahedral hohlraums.As a result,the injection angle of laser beams of 50°-60°was proposed as the optimum candidate range for the octahedral spherical hohlraums.We proposed a novel octahedral spherical hohlraum with cylindrical LEHs and LEH shields,in order to increase the laser coupling efficiency and improve the capsule symmetry and to mitigate the influence of the wall blowoff on laser transport.We studied on the sensitivity of the octahedral spherical hohlraums to random errors and compared the sensitivity among the octahedral spherical hohlraums,the rugby hohlraums and the cylindrical hohlraums,and the results show that the octahedral spherical hohlraums are robust to these random errors while the cylindrical hohlraums are the most sensitive.Up till to now,we have carried out three experiments on the spherical hohlraum with 2 LEHs on Shenguang(SG)laser facilities,including demonstration of improving laser transport by using the cylindrical LEHs in the spherical hohlraums,spherical hohlraum energetics on the SGIII prototype laser facility,and comparisons of laser plasma instabilities between the spherical hohlraums and the cylindrical hohlraums on the SGIII laser facility.Ke Lan Jie Liu Zhichao Li Xufei Xie Wenyi Huo Yaohua Chen Guoli Ren Chunyang Zheng Dong Yang Sanwei Li Zhiwen Yang Liang Guo Shu Li Mingyu Zhang Xiaoying Han Chuanlei Zhai Lifei Hou Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Feng Wang Guanghui Yuan Haijun Zhang Bobin Jiang Lizhen Huang Wei Zhang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Xuewei Deng Dongxia Hu Wei Zhou Huaiting Jia Yongkun Ding Wanguo Zheng Xiantu He 2016Matter and Radiation at Extremes2016,1,1:2
10A Neural Network Method for Monitoring Snowstorm: A Case Study in Southern China显示文摘It has been observed that low temperature, rainfall, snowfall, frost have never occurred over the past 50 years in the southern China, and weather in this area is very complex, so the monitoring equipments are few. Optical and thermal infrared remote sensing is influenced much by clouds, so the passive microwave Advanced Microwave Scanning Radiometer-Earth Observing System(AMSR-E) data are the best choice to monitor and analyze the development of disaster. In order to improve estimation accuracy, the dynamic learning neural network was used to retrieve snow depth. The difference of brightness temperatures of TB18.7V and TB36.5V, TB18.7H and TB36.5H, TB23.8V and TB89 V, TB23.8H and TB89 H are made as four main input nodes and the snow depth is the only one output node of neural network. The mean and the standard deviation of retrieval errors are about 4.8 cm and 6.7 cm relative to the test data of ground measurements. The application analysis indicated that the neural network can be utilized to monitor the change of snow intensity distribution through passive microwave data in the complex weather of the southern China.MAO Kebiao MA Ying XIA Lang SHEN Xinyi SUN Zhiwen HE Tianjue ZHOU Guanhua 2014Chinese Geographical Science2014,24,5:2
11Aggf1 attenuates hepatic inflammation and activation of hepatic stellate cells by repressing Ccl2 transcription显示文摘Liver injury represents a continuum of pathophysiological processes involving a complex interplay between hepatocytes, macrophages, and hepatic stellate cells. The mechanism whereby these intercellular interactions contribute to liver injury and fibrosis is not completely understood. We report here that angiogenic factor with G patch and FHA domains 1(Aggfl) was downregulated in the livers of cirrhotic patients compared to healthy controls and in primary hepatocytes in response to carbon tetrachloride(CC14) stimulation. Overexpression of Aggfl attenuated macrophage chemotaxis. Aggfl interacted with NF-κB to block its binding to the Ccl2 gene promoter and repressed Ccl2 transcription in hepatocytes. Macrophages cultured in the conditioned media collected from Aggfloverexpressing hepatocytes antagonized HSC activation. Taken together, our data illustrate a novel role for Aggfl in regulating hepatic inflammation and provide insights on the development of interventional strategies against cirrhosis.Wenping Xu Sheng Zeng Min Li Zhiwen Fan Bisheng Zhou 2017The Journal of Biomedical Research2017,31,5:2

19Monte Carlo simulation of the electromagnetic wave propagation in the duststorm显示文摘Monte Carlo simulations of the extinction rate of electromagnetic wave propagation in the duststorm were presented. The numerical procedure was based on the multiple scattering and independent scattering. The calculated multiple scattering attenuation rate is in good agreement with the measured one,but differs significantly from those obtained under the independent scattering assumption. At the same time,the factors of size parameter,frequency of incident wave,the angle of incident,and sands permittivity and water content have been considered in the attenuation of electromagnetic wave propagation in the duststorm. Numerical results obtained showed that the attenuation rate increases as the fractional volume,frequency of incident wave and sands permittivity increase,and as the angle of incident increases,the attenuation rate decreases.GAO ZhiWen ZHOU YouHe ZHENG XiaoJing 2008Science China(Physics,Mechanics & Astronomy)2008,51,8:1
20COUPLED THERMO-MECHANICAL ANALYSIS OF FUNCTIONALLY GRADIENT WEAK/MICRO-DISCONTINUOUS INTERFACE WITH GRADED FINITE ELEMENT METHOD显示文摘Coupled thermo-mechanical analysis of two bonded functionally graded materials subjected to thermal loads is conducted in this study with the graded finite element method. The thermal-mechanical properties of the bi-material interfaces are classified based on discontinuity degrees of their material properties and their derivatives at the interfaces. Numerical results indicate that discontinuity exerts remarkable effect on the temperature profile and stress value at the interface of two bonded functionally-graded materials. Under the thermal flux loading conditions, the stronger the interface discontinuity is, the smaller the heat flux is.Zhiwen Gao Kang Yong Lee Youhe Zhou 2012Acta Mechanica Solida Sinica2012,25,4:1
