| 1 | Optimization of Rural Settlement Distributions Based On the Ecological Security Pattern: A Case Study of Da’an City in Jilin Province of China显示文摘Following the trends of Chinese rural transformation development, and the sustainable development goals for resources and environment, reasonable arranging the potential development space and the ecological space, so as to optimize the distributions of rural settlement would be the key challenge for rural areas in ecologically fragile regions. From the perspective of maintaining regional ecological security, this paper takes Da’an City, a typical ecological fragile region in Jilin Province, as the case area, constructing the comprehensive ecological security pattern(ESP) on basis of landscape ecology, and applying the landscape pattern indexes to quantitative analysis the spatial distribution characteristics of rural settlements. Then, different optimization directions and management strategies are put forward for rural settlements in each secure zone under the comprehensive ESP. The experimental results showed that 1) the area of the low security zone, the general security zone, the moderate security zone and the extreme security zone was 1570.18 km^2, 1463.36 km^2, 1215.80 km^2 and 629.77 km^2, representing 32.18%, 29.99%, 24.92% and 12.91% of the total area of the target area, respectively. 2) The rural settlements in Da’an City were characterized by a high degree of fragmentation with a large number of small-scale patches. 3) The area of rural settlements in the ecological relocation zone, the in situ remediation zone, the limited development zone and the key development zone was 22.80 km^2, 42.31 km^2, 36.28 km^2 and 19.40 km^2, accounting for 18.88%, 35.03%, 30.04% and 16.06% of the total area of rural settlements, respectively. Then, different measures were proposed for settlements in different optimization zones in order to scientifically plan important ecological space, production space and living space in rural areas. This paper aims to provide fundamental support for rural settlements based on redistribution from the perspective of landscape ecology and provide insights for rural planning and rural habitat environmental improvement. | YIN Jingbo LI Hong WANG Dongyan LIU Shuhan | 2020 | Chinese Geographical Science2020，30，5： | 5 |
| 2 | Analysis of oral microorganism diversity in healthy individuals before and after chewing areca nuts using PCR-denatured gradient gel electrophoresis显示文摘To analyze oral microbial diversity in the saliva of 8 healthy individuals before and after chewing areca nuts. Saliva samples were collected before chewing areca nuts, after chewing areca nuts for 5 min and after chewing areca nuts for 30 min. DNA was extracted, and microbial diversity was examined using PCR-denaturing gradient gel electrophoresis(PCR-DGGE). When examining DGGE profiles collectively,the bands associated with Streptococcus and Veillonella were the most intense, making them the most prevalent bacteria. Furthermore, the band intensities did not decrease after chewing areca nuts for 5 or30 min; thus, these bacteria were unaffected. However, when examining some individuals, the band intensities for Streptococcus and Veillonella became more intense after 5 min of chewing and then returned to the pre-chewing level. This difference may be attributed to the mechanical movements of the oral cavity or individual differences. Other bacteria, such as Neisseria, Actinomycetes, and Rothia dentocariosa, were also found to have an increased or decreased prevalence following areca nut-chewing.Since the predominant species that are present following areca nut-chewing include Streptococcus and Veillonella, it would seem likely that these bacteria play an important role in the periodontal diseases associated with areca chewing. | Xiong Xiong Aixiang Hou Shuhan Yi Yichen Guo Ziwei Zhao Zhongkun Wu Huan Cheng Ke Li Zongjun Li Youhua Ren Yuanliang Wang | 2018 | Animal Nutrition2018，，3： | 2 |
| 3 | A Novel Electric Dual Motor Transmission for Heavy Commercial Vehicles显示文摘As a vital vehicle part,the powertrain system is undergoing a fast transition towards electrification.The new integrated electric drive system has been widely used,especially for passenger cars.In this work,a novel electric dual motor transmission is proposed for heavy commercial vehicles.The transmission scheme is firstly introduced,which can achieve 9 different operating modes including 5 single motor modes and 4 dual motor modes.Then,the mode shift map with minimum energy consumption is designed based on the motor efficiency map and the proposed energy management strategy.The driving power is appropriately distributed between the two motors in dual motor modes under the condition of minimum power consumption.In addition,a coordinated control strategy is developed for mode shift control without power interruption.The results show that the electric dual motor transmission has advantages in power consumption and power shift ability compared with the conventional single motor automated manual transmission. | Xiangyang Xu Jiajia Liang Qingjun Hao Peng Dong Shuhan Wang Wei Guo Yanfang Liu Zhonghua Lu Jiantao Geng Bin Yan | 2021 | Automotive Innovation2021，4，1： | 2 |
| 4 | Stability of Land-use/Land-cover in National Nature Reserves of Jilin Province, China显示文摘National nature reserves are an important part of classification management on ecological protection in China. Taking the national nature reserves of Jilin Province as examples, this paper introduced the stability index by referring to the intensity model of landuse and land-cover change(LUCC), and analyzed the overall stability of land-use and land-cover(LULC) in the study area from the time interval level and land category level. The stability of LULC in different types of nature reserves was tracked and identified by extracting land-use change trajectory, and the land-use change trajectory was divided into three types: stable type, sub-stable type and unstable type. The impact of LUCC on regional ecosystem services was studied by using hotspot analysis and gravity center analysis. The results showed that: 1) The LULC in the study area was stable on the whole, and the proportion of stable land area reached 86.08%. The intensity of LUCC showed an increasing trend in recent 20 years, and the conversion of cultivated land and construction land was active in continuous time interval. 2) The stability of LULC in forest ecological reserves and wildlife reserves in the eastern part of Jilin Province was the highest, while that in inland wetland reserves and geological relic reserves in the central and western part of Jilin Province was lower.3) The LUCC in national nature reserves not only changed the value of its own ecosystem service function, but also affected the ecosystem service function of the whole region. The combination of intensity analysis and land-use change trajectory was used to identify the characteristics of stability of LULC in nature reserves, which was conducive to deeply understand the process of LUCC in national nature reserves and provided reasonable suggestions for regional ecological protection. | SHANG Yi WANG Dongyan LIU Shuhan LI Hong | 2022 | Chinese Geographical Science2022，32，2： | 2 |
| 5 | Supramolecular Prodrug Micelles Constructed by Drug-Drug Conjugate with Water Soluble Pillar[6]arene for Controllable and Rapid Drug Release显示文摘The first attempt of constructing supramolecular prodrug micelles based on the host-guest interaction between water-soluble pillar[6]arene(WP6)and a novel doxorubicin(DOX)-based drug-drug conjugate(G)is reported,in which the drug-drug conjugate is synthesized by conjugating anticancer drug DOX with another drug isoniazide via the acid-cleavable hydrazone bond.The obtained WP6⊃G micelles are stable under physiological conditions,whereas the cumulative release of DOX is approximate to 100%within 30 min at pH 5.5 by simulating the endo-lysosomal environment at 37℃.Therefore,this WP6-based prodrug micelles can achieve efficient DOX ac-cumulation in the acidic tumor cells within a short period of time,which is very important and valuable;meanwhile it can also reduce the unexpected premature burst release under physiological condition.Furthermore,cellular in-ternalization and localization experiments demonstrated that these prodrug micelles enter cancer cells mainly via endocytosis and can lead to significant drug accumulation in SKOV3 cancer cells,implying its promising future for cancer therapy. | Yu Cao Xiaochun Zou Shuhan Xiong Yan Li Yingzhong Shen Xiaoyu Hu Leyong Wang | 2015 | Chinese Journal of Chemistry2015，33，3： | 2 |

| 8 | A Novel Bidirectional LSTM and Attention Mechanism Based Neural Network for Answer Selection in Community Question Answering显示文摘Deep learning models have been shown to have great advantages in answer selection tasks.The existing models,which employ encoder-decoder recurrent neural network(RNN),have been demonstrated to be effective.However,the traditional RNN-based models still suffer from limitations such as 1)high-dimensional data representation in natural language processing and 2)biased attentive weights for subsequent words in traditional time series models.In this study,a new answer selection model is proposed based on the Bidirectional Long Short-Term Memory(Bi-LSTM)and attention mechanism.The proposed model is able to generate the more effective question-answer pair representation.Experiments on a question answering dataset that includes information from multiple fields show the great advantages of our proposed model.Specifically,we achieve a maximum improvement of 3.8%over the classical LSTM model in terms of mean average precision. | Bo Zhang Haowen Wang Longquan Jiang Shuhan Yuan Meizi Li | 2020 | Computers, Materials & Continua2020，，3： | 1 |

| 16 | Thiol-ene crosslinked cellulose-based gel polymer electrolyte with good structural integrity for high cycling performance lithium-metal battery显示文摘Gel polymer electrolytes(GPEs) are considered to be one most promising alternative to liquid electrolytes due to their suitability for creating safe and durable solid-state lithium-metal batteries. However, the mechanical properties of GPEs usually deteriorate dramatically when polymer matrices are plasticized by a liquid electrolyte, which leads to significant loss of battery performance. Therefore, the long-term structural integrity and good mechanical strength are critical characteristics of GPEs designed for highperformance batteries. Here, an ecologically compatible cellulose-based GPE with a crosslinked structure is synthesized via a facile and effective thiol-ene click chemistry method. The prepared thiol-ene crosslinked GPE possesses enhanced mechanical strength(10.95 MPa) and rigid structure, which enabled us to fabricate Li Fe PO_(4)|Li batteries with ultra-long cycling performance. The capacity retention of the crosslinked cellulose-based GPE can be up to 84% at 0.5 C, even after 350 cycles, which is considerably higher than that of non-crosslinked GPE for which rapid decline in capacity occurs after 200 cycles. In addition, a GPE preparation method described in this work compares favorably well with existing commercial electrolytes for lithium metal batteries. | Hongbing Zhang Sijie Wang Yujie Wang Shuhan Dong Wen Chen De Li Feng Yu Yong Chen | 2023 | Chinese Chemical Letters2023，34，4： | 1 |
