| 1 | Reductions in non-point source pollution through different management practices for an agricultural watershed in the Three Gorges Reservoir Area显示文摘Non-point source water pollution generated by agricultural production is considered a major environmental issue in the Three Gorges Reservoir Area(TGRA) of China.The Annualised Agricultural Non-Point Source Pollution(AnnAGNPS) model was selected to assess the impact of the application of various management treats,including seven crops,five fertilizer levels and three-group management practice scenarios,on water quality from Heigou River Watershed in TGRA.The scenario subsets include conservation tillage practice(CTP),conservation reserve program(CRP) and conversion of cropland into forestland program(CCFP).Results indicated that tea can not be replaced by other crops because comparatively tea resulted in a higher sediment yield.CTP with no-tillage was more effective to reduce sediment yield,but could increased nutrient loss.CRP reduced sediment yield significantly,but slightly benefited on nutrient loss.CCFP reduced not only sediment yield but also the nutrient loss significantly.The conversion of cropland with a slope greater than 10 ° into forestland was found to be the best scenario as the sediment yield export is less than 5 tons/ha and nutrient loss is within the permissible limit. | Yaowu Tian Zhilin Huang Wenfa Xiao | 2010 | Journal of Environmental Sciences2010，22，2： | 13 |

| 3 | Intrusion detection based on system calls and homogeneous Markov chains显示文摘A novel method for detecting anomalous program behavior is presented, which is applicable to host-based intrusion detection systems that monitor system call activities. The method constructs a homogeneous Markov chain model to characterize the normal behavior of a privileged program, and associates the states of the Markov chain with the unique system calls in the training data. At the detection stage, the probabilities that the Markov chain model supports the system call sequences generated by the program are computed. A low probability indicates an anomalous sequence that may result from intrusive activities. Then a decision rule based on the number of anomalous sequences in a locality frame is adopted to classify the program's behavior. The method gives attention to both computational effciency and detection accuracy, and is especially suitable for on-line detection. It has been applied to practical host-based intrusion detection systems. | Tian Xinguang Duan Miyi Sun Chunlai Li Wenfa | 2008 | Journal of Systems Engineering and Electronics2008，19，3： | 8 |
| 4 | Top-emitting thermally activated delayed fluorescence organic light-emitting devices with weak light-matter coupling显示文摘Resonance interaction between a molecular transition and a confined electromagnetic field can lead to weak or strong light-matter coupling.Considering the substantial exciton–phonon coupling in thermally activated delayed fluorescence(TADF)materials,it is thus interesting to explore whether weak light-matter coupling can be used to redistribute optical density of states and to change the rate of radiative decay.Here,we demonstrate that the emission distribution of TADF emitters can be reshaped and narrowed in a top-emitting organic light-emitting device(OLED)with a weakly coupled microcavity.The Purcell effect of weak microcavity is found to be different for TADF emitters with different molecular orientations.We demonstrate that radiative rates of the TADF emitters with vertical orientation can be substantial increased in weakly coupled organic microcavity.These observations can enhance external quantum efficiencies,reduce efficiency roll-off,and improve color-purities of TADF OLEDs,especially for emitters without highly horizontal orientation. | Chunxiu Zang Shihao Liu Mengxin Xu Ruifang Wang Chen Cao Zelin Zhu Jiaming Zhang Hui Wang Letian Zhang Wenfa Xie Chun-Sing Lee | 2021 | Light(Science & Applications)2021，10，7： | 7 |
| 5 | Efficacy of platinum in advanced triple-negative breast cancer with germline BRCA mutation determined by next generation sequencing显示文摘Objective:To compare the efficacy of platinum-and non-platinum-based regimens as first-line treatment for advanced triple-negative breast cancer(TNBC)and analyze the relationship between their efficacy and BRCA gene status.Methods:Retrospectively analyze clinical data of 220 patients diagnosed pathologically with advanced TNBC and treated at the Department of Breast Oncology,Peking University Cancer Hospital from 2013 to 2018 and evaluate the efficacy of chemotherapy.A total of 114 patients had BRCA1/2 gene tested by next generation sequencing(NGS)using peripheral blood,and we analyzed the correlation between their efficacy and BRCA1/2 gene status.Results:Non-platinum-based chemotherapy(NPCT)was administered to 129 and platinum-based chemotherapy(PBCT)to 91 study patients.The clinical benefit rate(CBR)and median progression-free survival(PFS)were not statistically different between NPCT and PBCT groups.The median overall survival(OS)was 30.0 and 22.5 months for PBCT and NPCT group,respectively[P=0.090,hazard ratios(HR)=0.703].BRCA status was assessed in 114 patients,14 of whom had deleterious germline BRCA1/2(g BRCA)mutations(seven in each group).In PBCT group,the CBR was 85.7%and 35.1%for patients with and without deleterious g BRCA mutations,respectively(P=0.039).The median PFS were 14.9 and 5.3 months and median OS were 26.5 and 15.5 months for patients with and without deleterious g BRCA mutations,respectively(P=0.001,P=0.161,respectively).Patients in PBCT group had significantly greater rates of grade 3-4 anemia(5.5%vs.0%)and thrombocytopenia(8.8%vs.0%),whereas palmar-plantar erythrodysesthesia(12.4%vs.0%)and peripheral neuropathy(8.6%vs.1.1%)occurred more frequently in NPCT group.Conclusions:Platinum-based regimens are more effective in patients with deleterious g BRCA mutations,but no difference in patients without BRCA gene mutations,so non-platinum is an option in patients without BRCA gene mutations considering the toxicity and side effect.And we recommend that patients with advanced TNBC should have BRCA gene test. | Nan Wang Kun Li Wenfa Huang Weiyao Kong Xiaoran Liu Weijie Shi Feng Xie Hanfang Jiang Guohong Song Lijun Di Quanren Wang Jianjun Yu Huiping Li | 2020 | Chinese Journal of Cancer Research2020，32，2： | 7 |

| 8 | Auxin response factor 6A regulates photosynthesis,sugar accumulation,and fruit development in tomato显示文摘Auxin response factors(ARFs)are involved in auxin-mediated transcriptional regulation in plants.In this study,we performed functional characterization of SlARF6A in tomato.SlARF6A is located in the nucleus and exhibits transcriptional activator activity.Overexpression of SlARF6A increased chlorophyll contents in the fruits and leaves of tomato plants,whereas downregulation of SlARF6A decreased chlorophyll contents compared with those of wild-type(WT)plants.Analysis of chloroplasts using transmission electron microscopy indicated increased sizes of chloroplasts in SlARF6A-overexpressing plants and decreased numbers of chloroplasts in SlARF6A-downregulated plants.Overexpression of SlARF6A increased the photosynthesis rate and accumulation of starch and soluble sugars,whereas knockdown of SlARF6A resulted in opposite phenotypes in tomato leaves and fruits.RNA-sequence analysis showed that regulation of SlARF6A expression altered the expression of genes involved in chlorophyll metabolism,photosynthesis and sugar metabolism.SlARF6A directly bound to the promoters of SlGLK1,CAB,and RbcS genes and positively regulated the expression of these genes.Overexpression of SlARF6A also inhibited fruit ripening and ethylene production,whereas downregulation of SlARF6A increased fruit ripening and ethylene production.SlARF6A directly bound to the SAMS1 promoter and negatively regulated SAMS1 expression.Taken together,these results expand our understanding of ARFs with regard to photosynthesis,sugar accumulation and fruit development and provide a potential target for genetic engineering to improve fruit nutrition in horticulture crops. | Yujin Yuan Xin Xu Zehao Gong Yuwei Tang Mengbo Wu Fang Yan Xiaolan Zhang Qian Zhang Fengqing Yang Xiaowei Hu Qichen Yang Yingqing Luo Lihua Mei Wenfa Zhang Cai-Zhong Jiang Wangjin Lu Zhengguo Li Wei Deng | 2019 | Horticulture Research2019，6，1： | 3 |
| 9 | A flexible,multifunctional,optoelectronic anticounterfeiting device from high-performance organic light-emitting paper显示文摘As a primary anticounterfeiting technology,most paper anticounterfeiting devices take advantage of photoresponsive behaviors of certain security materials or structures,thus featuring low-security threshold,which has been a critical global issue.To incorporate optoelectronic devices into existing anticounterfeiting technology suggests a feasible avenue to address this challenge.Here we report a high-performance organic light-emitting paper-based flexible anticounterfeiting(FAC)device with multiple stimuli-responsiveness,including light,electricity,and their combination.Without sacrificing the preexisted security information on the paper,we fabricate FAC device in a facile,low-cost yet high-fidelity fashion by integrating patterned electro-responsive and photo-responsive organic emitters onto paper substrates.By introducing optical microcavities,the FAC device shows considerable color shift upon different viewing angle and applied voltage,which is easily discernible by naked eyes.Notably,the FAC device is bendable,unclonable,and durable(a half-lifetime over 4000 hours at 100 cd m^(−2)). | Teng Pan Shihao Liu Letian Zhang Wenfa Xie Cunjiang Yu | 2022 | Light(Science & Applications)2022，11，3： | 2 |
| 10 | Influencing Factors of Fine Root Production and Turnover in Forest Ecosystem显示文摘Fine roots(≤2mm in diameter) play important roles in carbon balance and nutrient recycling in forest ecosystem.With the development of the study on global carbon cycle,fine roots have attracted considerable attention as the main source of soil carbon in forest ecosystem.On the basis of synthetic analysis of research reports in domestic and foreign literatures,we summarized and elaborated the major abiotic and biotic factors that control fine root production and turnover.The environmental factors included soil nutrient,soil temperature,soil moisture and the CO2 concentration.Soil organisms,fine root morphology and forest stand characteristics were discussed as biotic factors in this paper.Finally,we defined the problems arising in root system research and prospected the future research direction. | Wang Ruili Cheng Ruimei Xiao Wenfa Feng Xiaohui Liu Zebin Wang Xiaorong | 2012 | Chinese Forestry Science and Technology2012，11，3： | 2 |

| 17 | The impact of concurrent variation of atmospheric meridional heat transport in western Baffen Bay and eastern Greenland on summer Arctic sea ice显示文摘Based on the climatological reanalysis data of the European Center for Medium-Range Weather Forecasts and the Arctic sea ice data of the National Snow and Ice Data Center, the relationship between the Arctic sea ice area(SIA)and the interannual variation of atmospheric meridional heat transport(AMHT) was analyzed. The results show that the atmospheric meridional heat transported by transient eddy(TAMHT) dominates the June AMHT in midhigh latitudes of the Northern Hemisphere, while the western Baffin Bay(B) and the eastern Greenland(G) are two gates for TAMHT entering the Arctic. TAMHT in the western Baffin Bay(B-TAMHT) and eastern Greenland(G-TAMHT) has a concurrent variation of reverse phase, which is closely related to the summer Arctic SIA.Possible mechanism is that the three Arctic atmospheric circulation patterns(AD, AO and NAO) in June can cause the concurrent variation of TAMHT in the B and G regions. This concurrent variation helps to maintain AD anomaly in summer through wave action and changes the polar air temperature, thus affecting the summer Arctic SIA. Calling the heat entering the Arctic as warm transport and the heat leaving Arctic as cold transport, then the results are classified into three situations based on B-TAMHT and G-TAMHT: warm B corresponding to cold G(WC), cold B corresponding to warm G(CW), cold B corresponding to cold G(CC), while warm B corresponding to warm G is virtually non-existent. During the WC situation, the SIA in the Pacific Arctic sediments and Kara Sea decreases;during the CW situation, the SIA in the Laptev Sea and Kara Sea decreases;during the CC situation, the SIA in the Kara Sea, Laptev Sea and southern Beaufort Sea increases. | Le Wang Lujun Zhang Wenfa Yang | 2020 | Acta Oceanologica Sinica2020，39，8： | 1 |
