| 1 | Simple and cost-effective methods for precise analysis of trace element abundances in geological materials with ICP-MS显示文摘Inductively coupled plasma mass spectrometry(ICP-MS) is the most commonly used technique to determine the abundances of trace elements in a wide range of geological materials. However, incomplete sample digestion, isobaric interferences and instrumental drift remain obvious problems that must be overcome in order to obtain precise and accurate results. For this reason, we have done many experiments and developed a set of simple, cost-effective and practical methods widely applicable for precise and rapid determination of trace element abundances in geological materials using ICP-MS. Commonly used high-pressure digestion technique is indeed effective in decomposing refractory phases, but this inevitably produces fluoride complexes that create new problems. We demonstrate that the fluoride complexes formed during high-pressure digestion can be readily re-dissolved using high-pressure vessel at 190 °C for only 2 h for 50 mg sample. In the case of isobaric interferences, although oxide(e.g., MO+/M+) and hydroxide(e.g., MOH+/M+) productivity is variable between runs, the(MO+/M+)/(Ce O+/Ce+)and(MOH+/M+)/(Ce O+/Ce+) ratios remain constant, making isobaric interference correction for all other elements of interest straightforward, for which we provide an easy-to-use off-line procedure. We also show that mass-time-intensity drift curve is smooth as recognized previously, for which the correction can be readily done by analyzing a quality-control(QC) solution and using off-line Excel VBA procedure without internal standards. With these methods, we can produce data in reasonable agreement with recommended values of international rock reference standards with a relative error of <8% and precision generally better than 5%. Importantly, compared to the widely used analytical practice, we can effectively save >60% of time(e.g., <24 h vs. >60 h). | Shuo Chen Xiaohong Wang Yaoling Niu Pu Sun Meng Duan Yuanyuan Xiao Pengyuan Guo Hongmei Gong Guodong Wang Qiqi Xue | 2017 | Science Bulletin2017，62，4： | 17 |
| 2 | Nanophotonic media for artificial neural inference显示文摘We show optical waves passing through a nanophotonic medium can perform artificial neural computing.Complex information is encoded in the wavefront of an input light. The medium transforms the wavefront to realize sophisticated computing tasks such as image recognition. At the output, the optical energy is concentrated in well-defined locations, which, for example, can be interpreted as the identity of the object in the image.These computing media can be as small as tens of wavelengths and offer ultra-high computing density. They exploit subwavelength scatterers to realize complex input/output mapping beyond the capabilities of traditional nanophotonic devices. | ERFAN KHORAM ANG CHEN DIANJING LIU LEI YING QIQI WANG MING YUAN ZONGFU YU | 2019 | Photonics Research2019，7，8： | 16 |
| 3 | A bHLH transcription activator regulates defense signaling by nucleo-cytosolic trafficking in rice显示文摘Crosstalk between plant hormone signaling pathways is vital for controlling the immune response during pathogen invasion.Salicylic acid(SA)and jas-monic acid(JA)often play important but antagonistic roles in the immune responses of higher plants.Here,we identify a basic helix-loop-helix transcription acti-vator,OsbHLH6,which confers disease resistance in rice by regulating SA and JA signaling via nucleo-cytosolic trafficking in rice(Oryza sativa).OsbHLH6 expression was upregulated during Magnaporthe oryzae infection.Transgenic rice plants overexpressing OsbHLH6 display increased JA responsive gene expression and enhanced disease susceptibility to the pathogen.Nucleus-localized OsbHLH6 activates JA signaling and suppresses SA signaling;however,the SA regulator OsNPR1(Nonexpressor of PR genes 1)sequesters OsbHLH6 in the cytosol to alleviate its effect.Our data suggest that OsbHLH6 controls disease re-sistance by dynamically regulating SA and JA signaling. | Fanwei Meng Chao Yang Jidong Cao Huan Chen Jinhuan Pang Qiqi Zhao Zongyi Wang Zheng Qing Fu Jun Liu | 2020 | Journal of Integrative Plant Biology2020，62，10： | 10 |
| 4 | Dynamic Load Restoration Considering the Interdependencies Between Power Distribution Systems and Urban Transportation Systems显示文摘After a major outage,mobile emergency resources(MERs)can be dispatched via the transportation system(TS)for service restoration to critical loads in the power distribution system(PDS).In this case study,the efficiency of service restoration in the PDS is associated with the traffic efficiency of the TS,and vice versa,because the PDS and TS are mutually coupled through traffic lights and MERs.This paper proposes a service restoration method considering interdependency between the PDS and TS,which is formulated as a mixed-integer linear program(MILP).The objective includes maximizing the efficiency of both PDS restoration and TS.By solving the MILP,the dynamic load restoration and MER dispatch strategies can be obtained.For the PDS,the availability of MERs,including mobile sources and repair crews,relates to their dispatch in the TS,and their relationship is formulated as mathematical models.For the TS,the dynamic traffic flow is modeled using the cell transmission model and the effect of traffic lights is considered.Case studies validate the effectiveness of the proposed method. | Ying Wang Yin Xu Jiaxu Li Chen Li Jinghan He Jiayu Liu Qiqi Zhang | 2020 | CSEE Journal of Power and Energy Systems2020，6，4： | 9 |
| 5 | A GmNINa-miR172c-NNC1 Regulatory Network Coordinates the Nodulation and Autoregulation of Nodulation Pathways in Soybean显示文摘Symbiotic root nodules are root lateral organs of plants in which nitrogen-fixing bacteria(rhizobia)convert atmospheric nitrogen to ammonia.The formation and number of nodules in legumes are precisely controlled by a rhizobia-induced signal cascade and host-controlled autoregulation of nodulation(AON).However,how these pathways are integrated and their underlying mechanisms are unclear.Here,we report that microRNA172c(miR172c)activates soybean(Glycine max)R hizobia-induced CLE1(GmRICI)and GmRIC2 by removing the transcriptional repression of these genes by Nodule Number Control 1(NNC1),leading to the activation of the AON pathway.NNC1 interacts with GmNINa,the soybean ortholog of Lotus NODULE INCEPTION(NIN),and hampers its transcriptional activation o i G m RICI and GmRIC2.Importantly,GmNINa acts as a transcriptional activator of miR172c.Intriguingly,NNC1 can transcriptionally repress miR172c expression,adding a negative feedback loop into the NNC1 regulatory network.Moreover,GmNINa interacts with NNC1 and can relieve the NNC1-mediated repression of miR172c transcription.Thus,the GmNINa-miR172c-NNC1 network is a master switch that coordinately regulates and optimizes NF and AON signaling,supporting the balance between nodulation and AON in soybean. | Lixiang Wang Zhengxi Sun Chao Su Yongliang Wang Qiqi Yan Jiahuan Chen Thomas Ott Xia Li | 2019 | Molecular Plant2019，12，9： | 7 |
| 6 | Chinmedomics facilitated quality-marker discovery of Sijunzi decoction to treat spleen qi deficiency syndrome显示文摘Sijunzi decoction (SJZD) is a Chinese classical formula to treat spleen qi deficiency syndrome (SQDS) and has been widely used for thousands of years.However,the quality control (QC) standards of SJZD are insufficient.Chinmedomics has been designed to discover and verify bioactive compounds of a variety of formularapidly.In this study,we used Chinmedomics to evaluate the SJZD's efficacy against SQDS to discover the potential quality-markers (q-markers) for QC.A total of 56 compounds in SJZD were characterized in vitro,and 23 compounds were discovered in vivo.A total of 58 biomarkers were related to SQDS,and SJZD can adjust a large proportion of marker metabolites to normal level and then regulate the metabolic profile to the health status.A total of 10 constituents were absorbed as effective ingredients that were associated with overall efficacy.We preliminarily determined malonyl-ginsenoside Rb2 and ginsenoside Ro as the q-markers of ginseng;dehydrotumulosic acid and dihydroxy lanostene-triene-21-acid as the q-markers of poria;glycyrrhizic acid,isoglabrolide,and glycyrrhetnic acid as the q-markers of licorice;and 2-atractylenolide as the q-marker of macrocephala.According to the discovery of the SJZD q-markers,we can establish the quality standard that is related to efficacy. | Qiqi Zhao Xin Gao Guangli Yan Aihua Zhang Hui Sun Ying Han Wenxiu Li Liang Liu Xijun Wang | 2020 | Frontiers of Medicine2020，14，3： | 7 |
| 7 | Innovative endoscopic enucleations of the prostate--Xie’s Prostate Enucleations显示文摘In the past 2 decades,endoscopic enucleation of the prostate has become a safe and effective surgical treatment for benign prostatic hyperplasia(BPH),with comparable outcomes to traditional surgeries.Transurethral vapor enucleation and resection of the prostate(TVERP),transurethral vapor enucleation of the prostate(TVEP),and ultrasound-navigated TVEP(US-TVEP)are new,innovative endoscopic enucleation procedures.These procedures are named Xie’s Prostate Enucleations(Xie’s Procedures for short).Current clinical data indicate that Xie’s Procedures are safe and effective treatment options for patients with BPH,especially for patients with larger prostates.Further prospective,randomized clinical trials compared with traditional transurethral resection of prostate(TURP)are still needed. | Liping Xie Xiao Wang Hong Chen Xiangyi Zheng Ben Liu Shiqi Li Yeqing Mao Qiqi Mao Song Wang Jiangfeng Li Tillmann Loch | 2018 | Asian Journal of Urology2018，5，1： | 6 |
| 8 | Antiferromagnetic element Mn modified PtCo truncated octahedral nanoparticles with enhanced activity and durability for direct methanol fuel cells显示文摘Pt-based magnetic nano catalysts are one of the most suitable cand idates for electrocatalytic materials due to their high electrochemistry activity and retrievability.Unfortunately,the inferior durability prevents them from being scaled-up,limiting their commercial applications.Herein,an antiferromagnetic element Mn was introduced into PtCo nanostructured alloy to synthesize uniform Mn-PtCo truncated octahedral nanoparticles(TONPs)by one-pot method.Our results show that Mn can tune the blocking temperature of Mn-PtCo TONPs due to its an tiferromag netism.At low temperatures,Mn-PtCo TONPs are ferromag netic,and the coercivity in creases gradually with in creasi ng Mn contents.At room temperature,the Mn-PtCo TONPs display superparamag netic behavior,which is greatly helpful for in dustrial recycling.Mn doping can not only modify the electronic structure of PtCo TONPs but also enhanee electrocatalytic performance for methanol oxidation reaction.The maximum specific activity of Mn-PtCo-3 reaches 8.1 A`m^-2,3.6 times of commercial Pt/C(2.2 A·m^-2)and 1.4 times of PtCo TONPs(5.6 A`m^-2),respectively.The mass activity decreases by only 30%after 2,000 cycles,while it is 45%and 99%(nearly inactive)for PtCo TONPs and commercial Pt/C catalysts,respectively. | Qiqi Zhang Jialong Liu Tianyu Xia Jie Qi Haochang Lyu Baoyuan Luo Rongming Wang Yizhong Guo Lihua Wang and Shouguo Wang | 2019 | Nano Research2019，12，10： | 5 |
| 9 | Spatio-temporal variations of soil water content and salinity around individual Tamarix ramosissima in a semi-arid saline region of the upper Yellow River, Northwest China显示文摘Ecological restoration by Tamarix plants on semi-arid saline lands affects the accumulation, distribution patterns and related mechanisms of soil water content and salinity. In this study, spatio-temporal variations of soil water content and salinity around natural individual Tamarix ramosissima Ledeb. were invetigated in a semi-arid saline region of the upper Yellow River, Northwest China. Specifically, soil water content, electrical conductivity(EC_e), sodium adsorption ratio(SAR_e), and salt ions(including Na^+, K^+, Ca^(2+), Mg^(2+) and SO_4^(2–)) were measured at different soil depths and at different distances from the trunk of T. ramosissima in May, July, and September 2016. The soil water content at the 20–80 cm depth was significantly lower in July and September than in May, indicating that T. ramosissima plants absorb a large amount of water through the roots during the growing period, leading to the decreasing of soil water content in the deep soil layer. At the 0–20 cm depth, there was a salt island effect around individual T. ramosissima, and the EC_e differed significantly inside and outside the canopy of T. ramosissima in May and July. Salt bioaccumulation and stemflow were two major contributing factors to this difference. The SAR_e at the 0–20 cm depth was significantly different inside and outside the canopy of T. ramosissima in the three sampling months. The values of SAR_e at the 60–80 cm depth in May and July were significantly higher than those at the 0–60 cm depth and higher than that at the corresponding depth in September. The distribution of Na^+ in the soil was similar to that of the SAR_e, while the concentrations of K^+, Ca^(2+), and Mg^(2+) showed significant differences among the sampling months and soil depths. Both season and soil depth had highly significant effects on soil water content, EC_e and SAR_e, whereas distance from the trunk of T. ramosissima only significantly affected EC_e. Based on these results, we recommend co-planting of shallow-rooted salt-tolerant species near the Tamarix plants and avoiding planting herbaceous plants inside the canopy of T. ramosissima for afforestation in this semi-arid saline region. The results of this study may provide a reference for appropriate restoration in the semi-arid saline regions of the upper Yellow River. | yang benman wang ruoshui xiao huijie cao qiqi liu tao | 2018 | Journal of Arid Land2018，10，1： | 5 |

| 11 | Evaluation of the fishbone model in simulating the seismic response of multistory reinforced concrete moment-resisting frames显示文摘The fishbone model is a simplified numerical model for moment-resisting frames that is capable of modelling the effects of column-beam strength and stiffness ratios. The applicability of the fishbone model in simulating the seismic responses of reinforced concrete moment-resisting frames of different sets of column-beam strength and stiffness ratios are evaluated through nonlinear static, dynamic and incremental dynamic analysis on six prototype buildings of 4-, 8-and 12-stories. The results show that the fishbone model is practically accurate enough for reinforced concrete frames, although the assumption of equal joint rotation does not hold in all cases. In addition to the ground motion characteristics and the number of stories in the structures, the accuracy of the model also varies with the column-beam stiffness and strength ratios. The model performs better for strong column-weak beam frames, in which the lateral drift patterns are better controlled by the continuous stiffness provided by the strong columns. When the inelastic deformation is large, the accuracy of the model may be subjected to large record-to-record variability. This is especially the case for frames of weak columns. | Qu Zhe Gong Ting Li Qiqi Wang Tao | 2019 | Earthquake Engineering and Engineering Vibration2019，18，2： | 3 |
| 12 | Characterization of spoilage bacterial communities in chilled duck meat treated by kojic acid显示文摘Chilled duck meat is a popularly consumed meat in China but easily perishes at room/low temperature. Kojic acid is usually used as an antimicrobial. This study investigated the sensory scores, total bacteria number, and total volatile base nitrogen (TVB-N) value of chilled duck meat under kojic acid treatment during storage. The results presented that kojic acid suppressed the growth of spoilage bacteria and prolonged the shelf-life of chilled duck meat by at least two days. In further investigation, the bacterial community composition was explored through high-throughput sequencing. Pseudomonas spp. were the predominant spoilage bacteria after 6-day storage and were significantly suppressed by kojic acid. Besides, Brochothrix showed drug resistance and became the dominant bacteria in the kojic acid treated sample after 6-day storage. In conclusion, kojic acid maintained the sensorial, chemical, and microbial quality of duck meat stored at low temperatures. Meanwhile, kojic acid enriched the bacteria composition and showed strong antimicrobial activity against Pseudomonas spp. | Wenfu Hou Qiqi Yue Wen Liu Ji Wu Yang Yi Hongxun Wang | 2021 | Food Science and Human Wellness2021，10，1： | 3 |
| 13 | ZmOST1 mediates abscisic acid regulation of guard cell ion channels and drought stress responses显示文摘The phytohormone abscisic acid(ABA) is an important mediator in the drought response, participating in, among other processes, stomatal movements. In Arabidopsis thaliana, the serine/threonine protein kinase,OST1, regulates this response, but the function of its maize homolog has yet to be established. Here, we isolated ZmOST1 and show that its encoded protein indeed acts to regulate guard cell movement. ZmOST1 was ubiquitously expressed throughout the plant, being highly expressed in guard cells, and inducible both by exogenous ABA and water stress. Transient expression of a ZmOST1-GFP fusion protein, in maize mesophyll protoplasts, indicated its subcellular localization in the cytoplasm and nucleus. A Zmost1 loss-of-function mutant exhibited reduced sensitivity to ABA-activated slow anion channels in maize guard cells, and reduced drought tolerance. Constitutive expression of ZmOST1, in an A. thaliana ost1-1 mutant rescued the phenotype with respect both to the sensitivity of guard cell slow anion currents to ABA treatment and stomatal closure. Our findings indicate a positive regulatory role for ZmOST1 in guard cell ABA signaling and drought response in maize plants. | Qiqi Wu Mei Wang Jianlin Shen Donghua Chen Yu Zheng Wei Zhang | 2019 | Journal of Integrative Plant Biology2019，61，4： | 3 |

| 15 | Autophagy and skin wound healing显示文摘Autophagy is a lysosome-dependent,self-renewal mechanism that can degrade and recycle cellular components in eukaryotic cells to maintain the stability of the intracellular environment and the cells ability to cope with unfavorable environments.Numerous studies suggest that autophagy participates in regulating various cellular functions and is closely associated with the onset and progression of various diseases.Wound healing is a complex,multistep biological process that involves multiple cell types.Refractory wounds,which include diabetic skin ulcers,can seriously endanger human health.Previous studies have confirmed that autophagy plays an essential role in various phases of wound healing.Specifically,in the inflammatory phase,autophagy has an anti-infection effect and it negatively regulates the inflammatory response,which prevents excessive inflammation from causing tissue damage.In the proliferative phase,local hypoxia in the wound can induce autophagy,which plays a role in anti-apoptosis and anti-oxidative stress and promotes cell survival.Autophagy of vascular endothelial cells promotes wound angiogenesis and that of keratinocytes promotes their differentiation,proliferation and migration,which is conducive to the completion of wound re-epithelialisation.In the remodeling phase,autophagy of fibroblasts affects the formation of hypertrophic scars.Additionally,a refractory diabetic wound may be associated with increased levels of autophagy,and the regulation of mesenchymal stem cell autophagy may improve its application to wound healing.Therefore,understanding the relationship between autophagy and skin wound healing and exploring the molecular mechanism of autophagy regulation may provide novel strategies for the clinical treatment of wound healing. | Haiyue Ren Feng Zhao Qiqi Zhang Xing Huang Zhe Wang | 2022 | Burns & Trauma2022，10，1： | 2 |
| 16 | Spin filtering magnetic modulation and spin-polarization switching in hybrid ferromagnet/semiconductor structures显示文摘Electron spin-polarization modulation with a ferromagnetic strip of in-plane magnetization is analyzed in a hybrid ferromagnet/semiconductor filter device.The dependencies of electron spin-polarization on the strip’s magnetization strength,width and position have been systematically investigated.A novel magnetic control spin-polarization switch is proposed by inserting a ferromagnetic metal(FM)strip eccentric in relation to off the center of the spin filter,which produces the first energy level spin-polarization reversal.It is believed to be of significant importance for the realization of semiconductor spintronics multiple-value logic devices. | XU HuaiZhe WANG LiYing YAN QiQi ZHANG YaPing ZHANG ShiChao | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，6： | 2 |
| 17 | ERF4 affects fruit ripening by acting as a JAZ interactor between ethylene and jasmonic acid hormone signaling pathways显示文摘The regulation of apple(Malus domestica)fruit texture during ripening is complex and a fundamental determinant of its commercial quality.In climacteric fruit,ripening-related processes are regulated by ethylene(ET),and jasmonate(JA)is also involved in the ethylene biosynthesis pathway,mainly through the transcription factor MYC2.However,the molecular genetic mechanism for fruit ripening processes between the JA and ET signaling pathways still needs to be elucidated.In order to explore how JA regulates apple fruit ripening through ERF4,we used’Gala’and’Ralls Janet’fruit at different developmental stages as experimental materials to determine the fruit firmness and related gene expression analysis.Meanwhile,we carried out different hormone treatments on’Gala’fruit at ripening stage.Here,we show that ERF4 is a core JA signaling hub protein JASMONATE ZIM-DOMAIN(JAZ)interactor that affects ethylene signaling pathways.During fruit development,ERF4 represses the expression of ACS1 and ACO1 by interacting with JAZ,as well as with the JA-activated transcription factor MYC2.Ripening is promoted in JAZ-suppressed apples.Thus,ERF4 acts as a molecular link between ethylene and JA hormone signals,and the natural variation of the ERF4Ethylene-responsive binding factor-associated amphiphilic repression(EAR)motif decreases repression of ethylene biosynthesis genes. | Yanan Hu Hualin Sun Zhenyun Han Shuai Wang Ting Wang Qiqi Li Ji Tian Yi Wang Xinzhong Zhang Xuefeng Xu Zhenhai Han Ting Wu | 2022 | Horticultural Plant Journal2022，8，6： | 2 |

| 19 | Mn doping effects on the gate-tunable transport properties of Cd3As2 films epitaxied on GaAs显示文摘The Mn doping effects on the gate-tunable transport properties of topological Dirac semimetal Cd3As2 films have been investigated.Mn-doped Cd3As2 films are directly grown on GaAs(111)B substrates by molecular-beam epitaxy,during which the single crystal phase can be obtained with Mn concentration less than 2%.Shubnikov-de Haas oscillation and quantum Hall effect are observed at low temperatures,and electrons are found to be the dominant carrier in the whole temperature range.Higher Mn content results in smaller lattice constant,lower electron mobility and larger effective band gap,while the carrier density seems to be unaffected by Mn-doping.Gating experiments show that Shubnikov-de Haas oscillation and quantum Hall effect are slightly modulated by electric field,which can be explained by the variation of electron density.Our results provide useful information for understanding the magnetic element doping effects on the transport properties of Cd3As2 films. | Hailong Wang Jialin Ma Qiqi Wei Jianhua Zhao | 2020 | Journal of Semiconductors2020，41，7： | 2 |
