| 2 | Simultaneous pyridine biodegradation and nitrogen removal in an aerobic granular system显示文摘Simultaneous pyridine biodegradation and nitrogen removal were successfully achieved in a sequencing batch reactor(SBR) based on aerobic granules. In a typical SBR cycle, nitritation occurred obviously after the majority of pyridine was removed, while denitrification occurred at early stage of the cycle when oxygen consumption was aggravated. The effect of several key operation parameters, i.e., air flow rate, influent NH_4^+-N concentration,influent p H and pyridine concentration, on nitritation, pyridine degradation and total nitrogen(TN) removal, was systematically investigated. The results indicated that high air flow rate had a positive effect on both pyridine degradation and nitritation but a negative impact of overhigh air flow rate. With the increase of NH_4^+ dosage, both nitritation and TN removal could be severely inhibited. Slightly alkaline condition, i.e., pH 7.0–8.0, was beneficial for both pyridine degradation and nitritation. High pyridine dosage often resulted in the delay of both pyridine degradation and nitritation. Besides, extracellular polymeric substances production was affected by air flow rate, NH_4^+ dosage, pyridine dosage and p H.In addition, high-throughput sequencing analysis demonstrated that Bdellovibrio and Paracoccus were the dominant species in the aerobic granulation system. Coexistence of pyridine degrader, nitrification related species, denitrification related species, polymeric substances producer and self-aggregation related species was also confirmed by highthroughput sequencing. | Xiaodong Liu Shijing Wu Dejin Zhang Jinyou Shen Weiqing Han Xiuyun Sun Jiansheng Li Lianjun Wang | 2018 | Journal of Environmental Sciences2018，30，5： | 7 |
| 3 | Multimodal Identification by Transcriptomics and Multiscale Bioassays of Active Components in Xuanfeibaidu Formula to Suppress Macrophage-Mediated Immune Response显示文摘Xuanfeibaidu Formula (XFBD) is a Chinese medicine used in the clinical treatment of coronavirus disease 2019 (COVID-19) patients. Although XFBD has exhibited significant therapeutic efficacy in clinical practice, its underlying pharmacological mechanism remains unclear. Here, we combine a comprehensive research approach that includes network pharmacology, transcriptomics, and bioassays in multiple model systems to investigate the pharmacological mechanism of XFBD and its bioactive substances. High-resolution mass spectrometry was combined with molecular networking to profile the major active substances in XFBD. A total of 104 compounds were identified or tentatively characterized, including flavonoids, terpenes, carboxylic acids, and other types of constituents. Based on the chemical composition of XFBD, a network pharmacology-based analysis identified inflammation-related pathways as primary targets. Thus, we examined the anti-inflammation activity of XFBD in a lipopolysaccharide-induced acute inflammation mice model. XFBD significantly alleviated pulmonary inflammation and decreased the level of serum proinflammatory cytokines. Transcriptomic profiling suggested that genes related to macrophage function were differently expressed after XFBD treatment. Consequently, the effects of XFBD on macrophage activation and mobilization were investigated in a macrophage cell line and a zebrafish wounding model. XFBD exerts strong inhibitory effects on both macrophage activation and migration. Moreover, through multimodal screening, we further identified the major components and compounds from the different herbs of XFBD that mediate its anti-inflammation function. Active components from XFBD, including Polygoni cuspidati Rhizoma, Phragmitis Rhizoma, and Citri grandis Exocarpium rubrum, were then found to strongly downregulate macrophage activation, and polydatin, isoliquiritin, and acteoside were identified as active compounds. Components of Artemisiae annuae Herba and Ephedrae Herba were found to substantially inhibit endogenous macrophage migration, while the presence of ephedrine, atractylenolide I, and kaempferol was attributed to these effects. In summary, our study explores the pharmacological mechanism and effective components of XFBD in inflammation regulation via multimodal approaches, and thereby provides a biological illustration of the clinical efficacy of XFBD. | Lu Zhao Hao Liu Yingchao Wang Shufang Wang Dejin Xun Yi Wang Yiyu Cheng Boli Zhang | 2023 | Engineering2023，，1： | 5 |

| 5 | An Alamouti coded CP-FBMC-MIMO system with two transmit antennas显示文摘In this paper, we propose an Alamouti coding for filter bank multicarrier(FBMC) with cyclic prefix(CP) for two transmit antennas, which can avoid the imaginary interference problem existing in the conventional FBMC with multi-antenna systems. Instead of performing Alamouti coding on original data symbols, we perform Alamouti coding on pre-processing signal at the transmitter in our proposed scheme. We show that our proposed scheme has fast single-symbol maximum-likelihood(ML) decoding and achieves full spatial diversity. Simulation results show that the proposed scheme can achieve the BER performance of Alamouti coding under both of the flat-fading channel and the frequency-selective channel. Therefore, it is an efficient Alamouti coding scheme for CP-FBMC systems with two transmit antennas. | KONG DeJin XIA Xiang-Gen JIANG Tao | 2015 | Science China(Information Sciences)2015，58，10： | 4 |

| 7 | Genesis of the Changba–Lijiagou Giant Pb-Zn Deposit, West Qinling, Central China: Constraints from S-Pb-C-O isotopes显示文摘The extensive Changba-Lijiagou Pb-Zn deposit is located in the north of the Xihe–Chengxian ore cluster in West Qinling. The ore bodies are mainly hosted in the marble, dolomitic marble and biotite-calcite-quartz schist of the Middle Devonian Anjiacha Formation, and are structurally controlled by the fault and anticline. The ore-forming process can be divided into three main stages, based on field geological features and mineral assemblages. The mineral assemblages of hydrothermal stage I are pale-yellow coarse grain, low Fe sphalerite, pyrite with pits, barite and biotite. The mineral assemblages of hydrothermal stage II are black-brown cryptocrystalline, high Fe shalerite, pyrite without pits, marcasite or arsenopyrite replace the pyrite with pits, K-feldspar. The features of hydrothermal stage III are calcite-quartz-sulfide vein cutting the laminated, banded ore body. Forty-two sulfur isotope analyses, twenty-five lead isotope analyses and nineteen carbon and oxygen isotope analyses were determined on sphalerite, pyrite, galena and calcite. The δ34 S values of stage I(20.3 to 29.0‰) are consistent with the δ34 S of sulfate(barite) in the stratum. Combined with geological feature, inclusion characteristics and EPMA data, we propose that TSR has played a key role in the formation of the sulfides in stage I. The δ34 S values of stage II sphalerite and pyrite(15.1 to 23.0‰) are between sulfides in the host rock, magmatic sulfur and the sulfate(barite) in the stratum. This result suggests that multiple S reservoirs were the sources for S2-in stage II. The δ34 S values of stage III(13.1 to 22‰) combined with the structure of the geological and mineral features suggest a magmatic hydrothermal origin of the mineralization. The lead isotope compositions of the sulfides have 206 Pb/204 Pb ranging from 17.9480 to 17.9782, 207 Pb/204 Pb ranging from 15.611 to 15.622, and 208 Pb/204 Pb ranging from 38.1368 to 38.1691 in the three ore-forming stages. The narrow and symmetric distributions of the lead isotope values reflect homogenization of granite and mantle sources before the Pb-Zn mineralization. The δ13 CPDB and δ18 OSMOW values of stage I range from-0.1 to 2.4‰ and from 18.8 to 21.7‰. The values and inclusion data indicate that the source of fluids in stage I was the dissolution of marine carbonate. The δ13 CPDB and δ18 OSMOW values of stage II range from-4 to 1‰ and from 12.3 to 20.3‰, suggesting multiple C-O reservoirs in the Changba deposit and the addition of mantle-source fluid to the system. The values in stage III are-3.1‰ and 19.7‰, respectively. We infer that the process of mineralization involved evaporitic salt and sedimentary organic-bearing units interacting through thermochemical sulfate reduction through the isotopic, mineralogy and inclusion evidences. Subsequently, the geology feature, mineral assemblages, EPMA data and isotopic values support the conclusion that the ore-forming hydrothermal fluids were mixed with magmatic hydrothermal fluids and forming the massive dark sphalerite, then yielding the calcite-quartz-sulfide vein ore type at the last stage. The genesis of this ore deposit was epigenetic rather than the previously-proposed sedimentary-exhalative(SEDEX) type. | WEI Ran WANG Yitian MAO Jingwen HU Qiaoqing QIN Siting LIU Shengyou YE Dejin YUAN Qunhu DOU Ping | 2020 | Acta Geologica Sinica(English Edition)2020，94，4： | 4 |
| 8 | Exact solutions of dispersion equation for MHD waves with short-wavelength modification显示文摘Dispersive magnetohydrodynamic (MHD) waves with short-wavelength modification have an important role in transforming energy from waves into particles.In this paper,based on the two-fluid mode,a dispersion equation,including the short-wavelength effect,and its exact solution are presented.The outcome is responsible for the short-wavelength modification versions of the three ideal MHD modes (i.e.the fast,slow and Alfve'n).The results show that the fast and Alfve'n modes are modified considerably by the shortwavelength effect mainly in the quasi-parallel and quasi-perpendicular propagation directions,respectively,while the slow mode can be affected by the short-wavelength effect in all propagation directions.On the other hand,the dispersive modification occurs primarily in the finite-β regime of 0.001 < β < 1 for the fast mode and in the high-β regime of 0.1 < β < 10 for the slow mode.For the Alfve'n mode,the dispersive modification occurs from the low-β regime of β < 0.001 through the high-β regime of β > 1. | CHEN Ling WU DeJin | 2011 | Chinese Science Bulletin2011，56，10： | 4 |
| 9 | Confined interface engineering of self-supported Cu@N-doped graphene for electrocatalytic CO_(2) reduction with enhanced selectivity towards ethanol显示文摘Electroreduction of greenhouse gas CO_(2) into value-added fuels and chemicals provides a promising pathway to address the issues of energy crisis and environmental change.However,the regulations of the selectivity towards C2 product and the competing hydrogen evolution reaction(HER)are major challenges for CO_(2) reduction reaction(CO_(2)RR).Here,we develop an interface-enhanced strategy by depositing a thin layer of nitrogen-doped graphene(N-G)on a Cu foam surface(Cu-N-G)to selectively promote the ethanol pathway in CO_(2)RR.Compared to the undetectable ethanol selectivity of pure Cu and Cu@graphene(Cu-G),Cu-N-G has boosted the ethanol selectivity to 33.1%in total Faradic efficiency(FE)at−0.8 V vs.reversible hydrogen electrode(RHE).The experimental and density functional theory(DFT)results verify that the interconnected graphene coating can not only serve as the fast charge transport channel but also provide confined nanospace for mass transfer.The N doping can not only trigger the intrinsic interaction between N in N-G and CO_(2) molecule for enriching the local concentration of reactants but also promote the average valence state of Cu for C–C coupling pathways.The confinement effect at the interface of Cu-N-G can not only provide high adsorbed hydrogen(Had)coverage but also stabilize the key*HCCHOH intermediate towards ethanol pathway.The provided interface-enhanced strategy herein is expected to inspire the design of Cubased CO_(2)RR electrocatalysts towards multi-carbon products. | Dejin Zang Xuejiao JGao Leyun Li Yongge Wei Haiqing Wang | 2022 | Nano Research2022，15，10： | 3 |
| 10 | IN SlTU TRUING/DRESSING OF DIAMOND WHEEL FOR PRECISION GRINDING显示文摘An application for achieving on-machine truing/dressing and monitoring of diamond wheel is dealt with in dry grinding.A dry electrical discharge(ED)assisted truing and dressing method is adopted in preparation of diamond grinding wheels.Effective and precise troing/dressing of a diamond wheel is carried out on a CNC curve grinding machine by utilizing an ED assisted diamond dresser.The dressed wheel is monitored online by a CCD vision system.It detects the topography changes of a wheel surface.The wear condition is evaluated by analyzing the edge deviation of a wheel image.The benefits of the proposed methods are confirmed by the grinding experiments.The designed truing/dressing device has high material removal rate,low dresser wear,and hence guarantees a desired wheel surface.Real-time monitoring of the wheel profile facilitates determining the optimum dressing amount,dressing interval,and the compensation error. | WAN Daping WANG Yan HU Dejin | 2008 | Chinese Journal of Mechanical Engineering2008，21，3： | 3 |
| 11 | Lacunar infarction with leukoaraiosis may aggravate cognitive dysfunction显示文摘This study semi-quantitatively analyzed the effects of leukoaraiosis.Patients with moderate or severe lacunar infarction were found to exhibit low scores on the Montreal Cognitive Assessment Scale (F=12.02,P=0.000),and prolonged P300 Cz2.0 latency (F=16.04,P=0.000).Correlation analysis revealed that the occurrence of leukoaraiosis was negatively correlated with Montreal Cognitive Assessment scores (r=-0.416,P=0.000),and positively correlated with P300 Cz2.0 latency (r=0.538,P=0.000).These findings indicate that leukoaraiosis aggravates cognitive impairment in patients with lacunar infarction,such that more severe leukoaraiosis is associated with more severe cognitive decline. | Dejin Sun Xueqin Zhang Penju Liu Jiechun Chen Jinxia Cao Aixia Zhuang Qinghong Zeng Shouqin Feng Yi Zhang Jiandong Jiang | 2011 | Neural Regeneration Research2011，6，31： | 3 |

| 13 | The evidence for the evolution of interplanetary small flux ropes: Boundary layers显示文摘We have examined the Wind data in 1996 and identified 21 small interplanetary magnetic flux ropes(SIMFRs),and all the 21 SIMFRs have boundary layer structures.The durations of the boundary layers varied from several minutes to 30 minutes.These boundary layers also have properties of high proton temperature,density,and plasma beta.These boundary layers are formed by magnetic reconnections.In addition,in three events magnetic reconnections were occurring inside the boundary layers.It indicates that the flux rope structures have propagated for some period of time,and their boundaries were still evolving through interaction with the background solar wind.Namely it is very possible that the SIMFRs came from the solar corona. | FENG HengQiang WANG JieMin WU DeJin | 2012 | Chinese Science Bulletin2012，57，12： | 3 |
| 14 | A graphical tuning of PI~λ controllers for fractional-delay systems显示文摘This article provides a graphical parameter tuning method of PIλ controllers for fractional-order time-delay systems. First, the complete stabilizing region of PIλ controller in proportional-integral plane, for a fixed λ, is determined in terms of a graphical stability criterion applicable to fractional-delay systems. Then, the stabilizing region is maximized analytically with respect to parameter λ to expect the most various behaviors of the closed-loop systems. Finally, by defining appropriate functions relative to the requirements of gain and phase margins, the curves in the maximized stabilizing region satisfying the pre-specified gain and phase margins are drawn, which releases a flexible parameter tuning procedure. Numerical examples are given to illustrate the design steps. | Dejin WANG Jianghui ZHANG | 2011 | 控制理论与应用(英文版)2011，9，4： | 2 |

| 18 | Temporo-Spatial Distribution and Evolution of Ore Deposits in the West Sector of the Northern Qilian Mountains显示文摘The west sector of the northern Qilian Mountains is well-known for the Jingtieshan-type iron deposits. A new breakthrough has been made in prospecting for gold and copper in recent years. In this paper, the distribution characteristics of ore deposits in the study area are discussed from the viewpoint of tectonic evolution. It is suggested that there are 9 stages of mineralization from the Palaeoproterozoic to Indosinian. Four minerogenetic series and two minerogenetic subseries of ore deposits are recognized. Iron mineralization occurred in several stages, while most of the metals were accumulated in large amounts in the Caledonian. The enrichment and mineralization of gold is related to large-scale shear-strike-slip faults and the ascent and unloading of deep-seated fluids. | MAO Jingwen ZHANG Xiaoyu ZHANG Zhaochong REN Fengshou ZUO Guochao ZHANG Zuoheng YANG Jianmin WANG Zhiliang YE Dejin | 1999 | Acta Geologica Sinica(English Edition)1999，73，2： | 1 |
| 19 | Reducing Cyclic Prefix Overhead Based on Symbol Repetition in NB-IoT-Based Maritime Communication显示文摘With the increasing maritime activities,a great demand of wide-area maritime digital data services is needed.Therefore,Narrowband Internet of Things(NB-IoT)that can provide wide coverage has been expected as an application for maritime communication networks(MCNS).In this paper,we aim to enhance the spectral efficiency in NB-IoT by reducing the cyclic prefix(CP)overhead in random access signal without causing interference.The key point of the proposed scheme is the symbols transmitted for multiple times repeatedly in NB-IoT.Specifically,all CP are removed and multi-path fading effect is eliminated by using a repeated symbol to cover the disturbed symbol to construct a circular convolution structure of the channel with the same effect as adding CP.In addition,a single-tap equalization is still appropriate.To validate the effectiveness of the proposed scheme,simulation results are carried out with respect to the bit error ratio(BER). | Tian Xiang Daiming Qu Faquan Zhang Dejin Kong | 2022 | China Communications2022，19，9： | 1 |
