| 1 | Mathematic principles of interrupted-sampling repeater jamming (ISRJ)显示文摘Coherent jamming is one of the important trends in modern radar electronic war- fare. High-speed sampling of wideband radio frequency (RF) signals and high iso- lation of two receive-transmit antennas are key technologies for the realization of coherent jamming. However, these technologies present significant challenges to engineering application. In this paper, a novel repeater jamming based on inter- rupted sampling technique is presented. For a jammer with a receive-transmit time-sharing antenna, a radar signal is sampled with a low rate by the jammer. Then, a train of false targets will be achieved after the jamming signal feed the matched filter of a pulse compression radar. For the case of the linear frequency modulated (LFM) pulse compression radars, mathematic principles of the interrupted-sam- pling repeater jamming is developed, and then the efficiency of the jamming is de- scribed and stated as expressions of key parameters which are also beneficial to the jamming design for other coherent radars. | WANG XueSong LIU JianCheng ZHANG WenMing FU QiXiang LIU Zhong XIE XiaoXia | 2007 | Science in China(Series F)2007，50，1： | 53 |
| 2 | Preliminary results pertaining to coseismic displacement and preseismic strain accumulation of the Lushan M_S7.0 earthquake,as reflected by GPS surveying显示文摘This paper presents the coseismic displacement and preseismic deformation fields of the Lushan MS7.0 earthquake that occurred on April 20,2013.The results are based on GPS observations along the Longmenshan fault and within its vicinity.The coseismic displacement and preseismic GPS results indicate that in the strain release of this earthquake,the thrust rupture is dominant and the laevorotation movement is secondary.Furthermore,we infer that any possible the rupture does not reach the earth’s surface,and the seismogenic fault is most likely one fault to the east of the Guanxian-Anxian fault.Some detailed results are obtainable.(1)The southern segment of the Longmenshan fault is locked preceding the Lushan earthquake.After the Wenchuan earthquake,the strain accumulation rate in the southeast direction accelerates in the epicenter of the Lushan earthquake,and the angle between the principal compressional strain and the seismogenic fault indicates that a sinistral deformation background in the direction of the seismogenic fault precedes the Lushan earthquake.Therefore,it is evident that the Wenchuan MS8.0 earthquake accelerated the pregnancy of the Lushan earthquake.(2)The coseismic displacements reflected by GPS data are mainly located in a region that is 230 km(NW direction)×100 km(SW direction),and coseismic displacements larger than 10 mm lie predominantly in a100-km region(NW direction).(3)On a large scale,the coseismic displacement shows thrust characteristics,but the associated values are remarkably small in the near field(within 70 km)of the earthquake fault.Meanwhile,the thrust movement in this70-km region does not correspond with the attenuation characteristics of the strain release,indicating that the rupture of this earthquake does not reach the earth’s surface.(4)The laevorotation movements are remarkable in the 50-km region,which is located in the hanging wall that is close to the earthquake fault,and the corresponding values in this case correlate with the attenuation characteristics of the strain release. | WU YanQiang JIANG ZaiSen WANG Min CHE Shi LIAO Hua LI Qiang LI Peng YANG YongLin XIANG HePing SHAO ZhiGang WANG WuXing WEI WenXin LIU XiaoXia | 2013 | Chinese Science Bulletin2013，58，28： | 33 |
| 3 | Granitic magmatism related to early Paleozoic continental collision in North Qinling显示文摘Zircon U-Pb dating of early Paleozoic granitoids in North Qinling yields three age peaks of^500,~452 and^420 Ma.They can be temporally correlated with high-pressure to ultrahigh-pressure metamorphism at ca.500 Ma,retrograde granulite-facies metamorphisms at ca.450 Ma and amphibolite-facies metamorphism at ca.420 Ma,respectively.The first episode of granitic magmatism is considered to have resulted from continental collision,whereas the second and third episodes of magmatism are attributed to crustal uplifting.Combined with the regional geological setting and new results from high-pressure and ultrahigh-pressure metamorphic rocks,the ca.500 Ma magmatism is interpreted as the result of partial melting of sedimentary rocks in accretionary wedge between the south Qinling microcontinent and the north Qinling belt including the southern margin of the North China Craton.The ca.450 Ma intensive magmatism is ascribed to dehydration melting of deeply subducted continental crust at thickened conditions in response to slab breakoff,and the final magmatism in ca.420 Ma is interpreted as the product of partial melting during the tectonic transition from contraction to extension. | ZHANG ChengLi LIU Liang WANG Tao WANG XiaoXia LI Lei GONG QiFu LI XiaoFei | 2013 | Chinese Science Bulletin2013，58，35： | 30 |
| 4 | Promotive Effects of Alginate-Derived Oligosaccharides on the Inducing Drought Resistance of Tomato显示文摘In order to determine the role of alginate-derived oligosaccharides (ADO) in drought stress resistance of tomato (Ly-copersicon esculentum Miller) seedlings, the leaves were exposed to different concentrations of ADO (0.05%, 0.10%, 0.20%, 0.30% and 0.50%) after drought stress was simulated by exposing the roots to 0.6 molL-1 PEG-6000 solution for 6 h. Changes in biomass, electrolyte leakage and malondialdehyde (MDA), free proline, total soluble sugars (TSS) and abscisic acid (ABA), the enzyme activities of catalase (CAT), superoxide dismutase (SOD), peroxidase (POD) and phenylalanine ammonia-lyase (PAL) were measured to investigate the effects of ADO treatment. The results showed that the treatment with an ADO concentration of 0.20% exhibited the highest performance of drought stress resistance in the tomato seedlings by decreasing the electrolyte leakage and the concentration of MDA, increasing the contents of free proline, TSS and ABA, and increasing the activities of CAT, SOD, POD and PAL after treatment with ADO. It is suggested that changes in electrolyte leakage, MDA, osmotic solutes, ABA, anti-oxidative enzyme and PAL activities were responsible for the increased drought stress resistance in tomato seedlings. To our best knowledge, this is the first report of the effect of ADO treatment on enhancing the drought stress resistance of tomato seedlings. | LIU Ruizhi JIANG Xiaolu GUAN Huashi LI Xiaoxia DU Yishuai WANG Peng MOU Haijin | 2009 | Journal of Ocean University of China2009，8，3： | 16 |

| 7 | Water chemistry controlled aggregation and photo-transformation of silver nanoparticles in environmental waters显示文摘The inevitable release of engineered silver nanoparticles(Ag NPs) into aquatic environments has drawn great concerns about its environmental toxicity and safety. Although aggregation and transformation play crucial roles in the transport and toxicity of Ag NPs, how the water chemistry of environmental waters influences the aggregation and transformation of engineered Ag NPs is still not well understood. In this study, the aggregation of polyvinylpyrrolidone(PVP) coated Ag NPs was investigated in eight typical environmental water samples(with different ionic strengths, hardness, and dissolved organic matter(DOM) concentrations) by using UV–visible spectroscopy and dynamic light scattering. Raman spectroscopy was applied to probe the interaction of DOM with the surface of Ag NPs. Further, the photo-transformation and morphology changes of Ag NPs in environmental waters were studied by UV–visible spectroscopy, inductively coupled plasma mass spectrometry, and transmission electron microscopy. The results suggested that both electrolytes(especially Ca2+and Mg2+) and DOM in the surface waters are key parameters for Ag NP aggregation, and sunlight could accelerate the morphology change, aggregation, and further sedimentation of Ag NPs. This water chemistry controlled aggregation and photo-transformation should have significant environmental impacts on the transport and toxicity of Ag NPs in the aquatic environments. | Yongguang Yin Xiaoya Yang Xiaoxia Zhou Weidong Wang Sujuan Yu Jingfu Liu Guibin Jiang | 2015 | Journal of Environmental Sciences2015，27，8： | 9 |

| 10 | Integrating a weighted-average method into the random walk framework to generate individual friend recommendations显示文摘Friend recommendation is a fundamental service in both social networks and practical applications,and is influenced by user behaviors such as interactions, interests, and activities. In this study, we first conduct in-depth investigations on factors that affect recommendation results. Next, we design Friend++, a hybrid multi-individual recommendation model that integrates a weighted average method(WAM) into the random walk(RW) framework by seamlessly employing social ties, behavior context, and personal information. In Friend++, the first plus signifies recommending a new friend through network features, while the second plus stands for using node features. To verify our method, we conduct experiments on three social datasets crawled from the Sina microblog system(Weibo). Experimental results show that the proposed method significantly outperforms six baseline methods in terms of recall, precision, F1-measure, and MAP. As a final step, we describe a case study that demonstrates the scalability and universality of our method. Through discussion, we reach a meaningful conclusion: although common interests are more important than user activities in making recommendations, user interactions may be the most important factor in finding the most appropriate potential friends. | Jibing GONG Xiaoxia GAO Hong CHENG Jihui LIU Yanqing SONG Mantang ZHANG Yi ZHAO | 2017 | Science China(Information Sciences)2017，60，11： | 7 |

| 12 | Whole-genome sequencing provides insights into the genetic diversity and domestication of bitter gourd(Momordica spp.)显示文摘Bitter gourd(Momordica charantia)is a popular cultivated vegetable in Asian and African countries.To reveal the characteristics of the genomic structure,evolutionary trajectory,and genetic basis underlying the domestication of bitter gourd,we performed whole-genome sequencing of the cultivar Dali-11 and the wild small-fruited line TR and resequencing of 187 bitter gourd germplasms from 16 countries.The major gene clusters(Bi clusters)for the biosynthesis of cucurbitane triterpenoids,which confer a bitter taste,are highly conserved in cucumber,melon,and watermelon.Comparative analysis among cucurbit genomes revealed that the Bi cluster involved in cucurbitane triterpenoid biosynthesis is absent in bitter gourd.Phylogenetic analysis revealed that the TR group,including 21 bitter gourd germplasms,may belong to a new species or subspecies independent from M.charantia.Furthermore,we found that the remaining 166 M.charantia germplasms are geographically differentiated,and we identified 710,412,and 290 candidate domestication genes in the South Asia,Southeast Asia,and China populations,respectively.This study provides new insights into bitter gourd genetic diversity and domestication and will facilitate the future genomics-enabled improvement of bitter gourd. | Junjie Cui Yan Yang Shaobo Luo Le Wang Rukui Huang Qingfang Wen Xiaoxia Han Nansheng Miao Jiaowen Cheng Ziji Liu Changyuan Zhang Chengcheng Feng Haisheng Zhu Jianwen Su Xinjian Wan Fang Hu Yu Niu Xiaoming Zheng Yulan Yang Dai Shan Zhensheng Dong Weiming He Narinder P.S.Dhillon Kailin Hu | 2020 | Horticulture Research2020，7，1： | 7 |

| 14 | Comparison of the short-term and long-term outcomes of laparoscopic hysterectomies and of abdominal hysterectomies: a case study of 4,895 patients in the Guangxi Zhuang Autonomous Region, China显示文摘Background: To evaluate the short-term and long-term outcomes after laparoscopic hysterectomy(LH) compared with abdominal hysterectomy(AH) in case of benign gynecological disease. Methods: A multi-center cohort retrospective comparative study of population among 4,895 hysterectomies(3,539 LH vs.1,356 AH) between 2007 and 2013 was involved. Operative time(OT), estimated blood loss(EBL), intra-operative and post-operative complications, passing flatus; days with indwelling catheter, questionnaires covering pelvic floor functions and sexual functions were assessed.Results: The EBL(174.1±157.4 vs. 263.1±183.2 cc, LH and AH groups, respectively), passing flatus(38.7±14.1 vs. 48.1±13.2 hours), days with indwelling catheter(1.5±0.6 vs. 2.2±0.8 days), use of analgesics(6.5% vs. 73.1%), intra-operative complication rate(2.4% vs. 4.1%), post-operative complication rate(2.3% vs. 5.7%), post-operative constipation(12.1% vs. 24.6%), mild and serious stress urinary incontinence(SUI) post-operative(P<0.001; P=0.014), and proportion of Female Sexual Functioning Index(FSFI) total score <26.55 post-operative(P<0.001) of the LH group were significantly less than those of AH group. There wereno significant differences in OT(106.5±34.5 vs. 106.2±40.3 min) between the two groups.Conclusions: LH is a safe and efficient operation for improving patients' long-term quality of life(Qo L), and LH is a cost-effectiveness procedure for treating benign gynecological disease. LH is superior to AH due to reduced EBL, reduced post-operative pain and earlier passing flatus. | Hongying He Zhijun Yang Dingyuan Zeng Jiangtao Fan Xiaoxia Hu Yuan Ye Hua Bai YanmingJiang Zhong Lin Zhiying Lei Xinlin Li Lian Li Jinghua Gan Ying Lan Xiongzhi Tang Danxia Wang Junsong Jiang Xiaoyan Wu Meiying Li Xiaoqing Ren Xiaomin Yang Mei Liu Qinmei Wang Fuyan jiang Li Li | 2016 | Chinese Journal of Cancer Research2016，28，2： | 6 |

| 16 | Preseismic deformation in the seismogenic zone of the Lushan MS7.0 earthquake detected by GPS observations显示文摘A continuous GPS array across the southern segment of the Longmenshan fault zone recorded the deformation during the process of the Lushan MS7.0 earthquake that occurred on April 20, 2013. Such data can provide meaningful information regarding the dynamic evolution of crustal deformation in the seismogenic zone. Our studies have shown that the occurrence of the Wenchuan earthquake led to the loading of compressive and sinistral shearing strain on the southern segment of the Maoxian-Wenchuan fault, whereby the extrusion strain accumulated at a greater rate than before the Wenchuan earthquake. The strain time series in the seismogenic zone revealed that the principal compression strain rates decreased from west to east in the direction of N30°–45°W. Furthermore, the area to the east of Beichuan-Yingxiu fault behaved as a zone of compressive deformation with obvious sinistral shearing deformation. The surface strain and the first shearing strain time series decreased with time, while the area to the west of the Beichuan-Yingxiu fault behaved as a zone of dextral shear deformation that increased with time. Furthermore, the regional deformation field before the Lushan earthquake showed that the rate of extrusion strain accumulation in the southern segment of the Longmenshan fault zone was obviously larger than before the Wenchuan earthquake. Moreover, the sinistral shearing strain accumulated in the area of the southern segment of the Maoxian-Wenchuan fault. Based on the above analysis, we consider that the eastward movement of the Bayan Har block increased considerably following the Wenchuan earthquake, which enhanced the accumulation of compression strain in the southern segment of the Longmenshan fault zone. | LIU XiaoXia WU YanQiang JIANG ZaiSen ZHAN Wei LI Qiang WEI WenXin ZOU ZhenYu | 2015 | Science China Earth Sciences2015，58，9： | 6 |
| 17 | Broadband near-infrared luminescence and energy transfer of Cr^(3+),Ce^(3+) co-doped Ca_(2)LuHf_(2)Al_(3)O_(12) phosphors显示文摘Broadband near-infrared phosphors are highly desirable for food testing.Targeted Ca_(2)LuHf_(2)Al_(3)O_(12):Cr^(3+)(CLHA:Cr^(3+)) and Ca_(2)LuHf_(2)Al_(3)O_(12):Ce^(3+),Cr^(3+)(CLHA:Ce^(3+),Cr^(^(3+))) phosphors were synthesized by the conventional high-temperature solid state reaction.The CLHA:Cr^(3+)phosphor,with a good thermal stability,shows a red shift owing to radiation reabsorption and non-radiative transition with increasing Cr^(3+)content.For co-doped sample,the emission intensity of Cr^(3+)can be enhanced by three times due to the energy transfer from Ce^(3+)to Cr^(3+),which can be evidenced by a significant overlap between the PLE of Cr^(3+)single-doped phosphor and the PL of Ce^(3+)single-doped phosphor.In addition,the mechanism of energy transfer is identified as a quadrupole-quadrupole interaction according to decay Lifetime and Dexter’s energy transfer formula.The broadband NIR emission peaked at 775 nm of CLHA:Cr^(3+),Ce^(3+)phosphor shows a bright prospect in nondestructive quality-control analysis systems for food. | Jinpin Wu Weidong Zhuang Ronghui Liu Yuanhong Liu Tongyu Gao Chunpei Yan Min Cao Junhang Tian Xiaoxia Chen | 2021 | Journal of Rare Earths2021，39，3： | 6 |
| 18 | Excessive gestational weight gain in early pregnancy and insufficient gestational weight gain in middle pregnancy increased risk of gestational diabetes mellitus显示文摘Background:Gestational weight gain(GWG)is associated with the risk of gestational diabetes mellitus(GDM).However,the effect of weight gain in different trimesters on the risk of GDM is unclear.This study aimed to evaluate the effect of GWG on GDM during different trimesters.Methods:A birth cohort study was conducted from 2017 to 2020 in Shenzhen,China.In total,51,205 participants were included comprising two models(early pregnancy model and middle pregnancy model).Gestational weight(kg)was measured at each prenatal clinical visit using a standardized weight scale.Logistic regression analysis was used to assess the risk of GDM.Interaction analysis and mediation effect analysis were performed in the middle pregnancy model.Results:In the early pregnancy model,the risk of GDM was 0.858 times lower(95%confidence interval[CI]:0.786,0.937)with insufficient GWG(iGWG)and 1.201 times higher(95%CI:1.097,1.316)with excessive GWG after adjustment.In the middle pregnancy model,the risk of GDM associated with iGWG increased 1.595 times(95%CI:1.418,1.794)after adjustment;for excessive GWG,no significant difference was found(P=0.223).Interaction analysis showed no interaction between GWG in early pregnancy(GWG-E)and GWG in middle pregnancy(GWG-M)(F=1.268;P=0.280).The mediation effect analysis indicated that GWG-M plays a partial mediating role,with an effect proportion of 14.9%.Conclusions:eGWG-E and iGWG-M are associated with an increased risk of GDM.Strict control of weight gain in early pregnancy is needed,and sufficient nutrition should be provided in middle pregnancy. | Aiqi Yin Fuying Tian Xiaoxia Wu Yixuan Chen Kan Liu Jianing Tong Xiaonian Guan Huafan Zhang Linlin Wu Jianmin Niu | 2022 | Chinese Medical Journal2022，，9： | 5 |
| 19 | Direct low-temperature synthesis of ultralong persistent luminescence nanobelts based on a biphasic solution-chemical reaction显示文摘Here, we report the direct hydrothermal synthesis of 1 D-based Zn_2 GeO_4:Mn^(2+) persistent luminescent nanobelts(ZGO:Mn PLNBs). The ZGO:Mn PLNBs exhibit rapid growth rate, and nanobelts can be obtained after 30 min of hydrothermal treatment. The persistent luminescence performance can be fine-turned upon prolonging the hydrothermal time. Furthermore, the doping ratio of Mn^(2+) exhibits influence on the persistent luminescence properties of ZGO:Mn PLNBs, and 2% doping of Mn^(2+) shows superior persistent luminescence with decay time of longer than 20 min. The developed 1 D-based ZGO:Mn PLNBs can be simply prepared with the hydrothermal method and show tunable morphology and persistent luminescence. We believe that this solid-state-reaction-free chemical approach avoids the current key drawback in regard to PLNMs development, and thus will promote the broad use of these unique nanostructured PLNMs in developing optical device for imaging. | Haoyang Liu Xiaoxia Hu Jie Wang Meng Liu Wei Wei Quan Yuan | 2018 | Chinese Chemical Letters2018，29，11： | 5 |
| 20 | Suspended zinc sulfide particles in the Southwest Indian Ridge area and their relationship with hydrothermal activity显示文摘Suspended particle samples collected in the water column at 7 stations in the hydrothermal vent area in the Southwest Indian Ridge were studied by electronic scanning microscope(SEM)and energy dispersive X-ray spectrometry(EDX).A method of zinc sulfide(ZnS)mineral phase identification by SEM and EDX data was proposed,and related adequacy and limitation of the method were presented.29 ZnS particles with various morphologies were found.27 sphalerite particles and two wurtzite particles were distinguished by joint consideration of their morphology and chemical element composition.Two types of sphalerite particles with different dissolving intensities were differentiated,which may be depended on the duration of the particles existence in the water column.More than half of the total sphalerite particles include 12high Fe-containing particles(Fe[10 wt%)were found at the Station 21VII-CTD7,suggesting a close link to the adjacent active hydrothermal vent.Sphalerite particles at Station 2VI-CTD3 contained only one Fe-containing particle and their amount ranked second among that at all the survey stations,suggesting a good correspondence to the adjacent inactive hydrothermal vent.Only six non-iron ZnS particles were found at the rest eastern 5 stations,suggesting a weak influence of hydrothermal activities in the eastern area. | Xiaoxia Sun Zuosheng Yang Dejiang Fan Ming Liu | 2014 | Chinese Science Bulletin2014，59，9： | 5 |
