| 1 | Soil Erosion Changes over the Past Five Decades in the Red Soil Region of Southern China显示文摘This paper reports the dynamic changes of soil and water loss in the red soil region of Southern China since the 1950s. The red soil region covers eight provinces: Jiangxi, Zhejiang, Fujian, Anhui, Hubei, Hunan, Guangdong and Hainan. From the 1950s to 1986, the annual rate of soil erosion increased by 3.4%. From 1986 to 1996 and from 1996 to 2000, the annual rates of soil erosion decreased by 2.0% and 0.32%, respectively. Field surveys showed that from 2000 to 2005, the area of soil and water loss decreased annually by 1.2%. This decrease was a result of large-scale erosion control activities across China. Although the eroded soil has been restored, the restoration process is very slow and full restoration will take a long time. Our report suggests that controlling soil and water loss is a challenging task, and additional measures must be taken to effectively control the soil erosion in the red soil region. | LIANG Yin LI Decheng LU Xixi YANG Xuan PAN Xianzhang MU Huan SHI Deming ZHANG Bin | 2010 | Journal of Mountain Science2010，7，1： | 18 |
| 2 | Genesis of the Wulong gold deposit,Liaoning Province,NE China:Constrains from noble gases,radiogenic and stable isotope studies显示文摘TheWulong lode deposit contains over 80 tonnes of gold with an average grade of 5.35 g/t.It is one of the largest deposits in Dandong City,Liaoning Province in northeast China.Previous studies on the deposit focused on its geological characteristics,geochemistry,fluid inclusions,and the timing of gold mineralization.However,controversy remains regarding the origin of the ore-forming fluids and metals,and the genesis of the gold deposit.This paper presents zircon UePb and pyrite RbeSr ages and S,Pb,He,and Ar isotopic results along with quartz H and O isotopic data for all litho-units associated with the deposit.Laser ablation inductively coupled mass spectrometry measurements yielded zircon UePb dates for samples of pre-mineralization rocks like granite porphyry dike,the Sanguliu granodiorite,fine-grained diorite,and syn-mineralization diorite,as well as post-mineralization dolerite,and lamprophyre;their emplacement ages are 1261 Ma,1241 Ma,1231 Ma,1201 Ma,1192 Ma,and 1152 Ma,respectively.The pyrite RbeSr isochron age is 1191 Ma,indicating that both magmatism and mineralization occurred during the Early Cretaceous.The d18OH2O values of ore-forming hydrothermal fluids from the quartzepolymetallic sulfide vein stage vary from 4.8&to 6.5&,and the dDV-SMOW values are between67.7&and75.9&,indicating that the ore-forming fluids were primarily magmatic.The noble gas isotope compositions of fluid inclusions hosted in pyrite suggest that the ore-forming fluids were dominantly derived from crustal sources with minor mantle input.Sulfur isotopic values of pyrite vary between 0.2&and 3.5&,suggesting that S was derived from a homogeneous magmatic source or possibly from fluids derived from the crust.The Pb isotopic compositions of sulfides(207Pb/204Pb?15.51 e15.71,206Pb/204Pb?17.35e18.75,208Pb/204Pb?38.27e40.03)indicate that the Pb of the Wulong gold deposit is a mixture of crust and mantle components.Geochronological and geochemical data,together with the regional geological history,indicate that Early Cretaceous magmatism and mineralization of the Wulong gold deposit occurred during the rollback of the subducting Paleo-Pacific Plate,which resulted in lithospheric thinning and the destruction of the North China Craton(NCC),which indicates that the deposit is of magmaticehydrothermal origin. | Peng Zhang Linlin Kou Yan Zhao Zhongwei Bi Deming Sha Renping Han Zhumin Li | 2020 | Geoscience Frontiers2020，11，2： | 13 |
| 3 | miR-25 modulates triacylglycerol and lipid accumulation in goat mammary epithelial cells by repressing PGC-1beta显示文摘Background: The goat(Caprahircus) is one of the most important livestock animals. Goat milk fat is an important component in the nutritional quality of goat milk. Growing evidence points to the critical roles of microRNAs(miRNAs) in lipid metabolism.Results: Using a highly sensitive method of S-poly(T) plus for miRNAs detection, we analyze the expression patterns of 715 miRNAs in goat mammary gland tissues at different stages of lactation. We observed that miR-25 expression had an inverse relationship with milk production. Overexpression of miR-25 significantly repressed triacylglycerol synthesis and lipid droplet accumulation. To explore the regulatory mechanism of miR-25 in milk lipid metabolism,we analyzed its putative target genes with bioinformatics analysis followed by 3′-UTR assays. Peroxisome proliferative activated receptor gamma coactivator 1 beta(PGC-1 beta), a key regulator of lipogenics was identified as a direct target of miR-25 with three specific sites within its 3′-UTR. In addition, miR-25 mimics in goat mammary epithelial cells reduced the expressions of genes involved in lipid metabolism.Conclusions: Taken together, our results show miR-25 is potentially involved in lipid metabolism and we reveal the function of the miR-25/PGC-1 beta regulatory axis during lactation. | Liuan Ma Huiling Qiu Zhi Chen Li Li Yan Zeng Jun Luo Deming Gou | 2018 | Journal of Animal Science and Biotechnology2018，9，4： | 9 |
| 4 | Ultra-high resolution strain sensor network assisted with an LS-SVM based hysteresis model显示文摘Optical fiber sensor network has attracted considerable research interests for geoscience applications.However,the sensor capacity and ultra-low frequency noise limits the sensing performance for geoscience data acquisition.To achieve a high-resolution and lager sensing capacity,a strain sensor network is proposed based on phase-sensitive op-tical time domain reflectometer(φ-OTDR)technology and special packaged fiber with scatter enhanced points(SEPs)ar-ray.Specifically,an extra identical fiber with SEPs array which is free of strain is used as the reference fiber,for com-pensating the ultra-low frequency noise in theφ-OTDR system induced by laser source frequency shift and environment temperature change.Moreover,a hysteresis operator based least square support vector machine(LS-SVM)model is in-troduced to reduce the compensation residual error generated from the thermal hysteresis nonlinearity between the sensing fiber and reference fiber.In the experiment,the strain sensor network possesses a sensing capacity with 55 sensor elements.The phase bias drift with frequency below 0.1 Hz is effectively compensated by LS-SVM based hyster-esis model,and the signal to noise ratio(SNR)of a strain vibration at 0.01 Hz greatly increases by 24 dB compared to that of the sensing fiber for direct compensation.The proposed strain sensor network proves a high dynamic resolution of 10.5 pε·Hz-1/2 above 10 Hz,and ultra-low frequency sensing resolution of 166 pεat 0.001 Hz.It is the first reported a large sensing capacity strain sensor network with sub-nεsensing resolution in mHz frequency range,to the best of our knowledge. | Tao Liu Hao Li Tao He Cunzheng Fan Zhijun Yan Deming Liu Qizhen Sun | 2021 | Opto-Electronic Advances2021，4，5： | 4 |
| 5 | Ultracompact dual-mode waveguide crossing based on subwavelength multimode-interference couplers显示文摘We propose and experimentally demonstrate a novel ultracompact dual-mode waveguide crossing based on subwavelength multimode-interference couplers for a densely integrated on-chip mode-division multiplexing system.By engineering the lateral-cladding material index and manipulating phase profiles of light at the nanoscale using an improved inverse design method, a subwavelength structure could theoretically realize the identical beat length for both TE_0 and TE1, which can reduce the scale of the device greatly. The fabricated device occupied a footprint of only 4.8 μm× 4.8 μm. The measured insertion losses and crosstalks were less than 0.6 d B and-24 d B from 1530 nm to 1590 nm for both TE0 and TE1 modes, respectively. Furthermore, our scheme could also be expandedto design waveguide crossings that support more modes. | WEIJIE CHANG LULUZI LU XINSHU REN DONGYU LI ZEPENG PAN MENGFAN CHENG DEMING LIU MINMING ZHANG | 2018 | Photonics Research2018，6，7： | 4 |
| 6 | Analysis of output voltage on a planar insulating core transformer显示文摘Output voltage is an important performance characteristic of planar insulating core transformer (PICT).In PICT magnetic cores are insulated from their neighboring magnetic cores by solid insulating materials.Solid insulating materials can increase leakage flux.This results in a low generated voltage in secondary coils,especially on the upper stages.Connecting flux compensation capacitors to secondary coils can compensate the flux loss.Design equations to calculate the flux compensation capacitors value and relevant simulation by CST and Protel software were presented.Simulation results of an actual PICT showed that output voltage increased by 19% after being connected to flux compensation capacitors and the voltage on every stage was equally distributed.Results of simulation were consistent with the following experimental test,which revealed that flux compensation capacitors were effective. | KANG Cheng LIU Yonghao LI Deming | 2012 | Nuclear Science and Techniques2012，23，1： | 3 |
| 7 | Comparison of seed germination of four Artemisia species (Asteraceae) in northeastern Inner Mongolia,China显示文摘Two psammophile-dominated Artemisia semi-shrubs (A.wudanica and A.halodendron) and two annual Artemisia forbs (A.sieversiana and A.scoparia) bear significant ecological functions in Horqin Sandy Land,but systematical information on their achenes' germination is very limited.A set of studies were conducted to evaluate seed germination responses to storage periods and methods,different temperatures,lights conditions and sand burial depths,in order to determine inter-specific germination variation in the same genus and to explain how the species adapt to its microhabitat.Fresh achenes of A.wudanica,A.halodendron and A.sieversiana showed high germination capacities,but those of A.scoparia had obvious innate dormancy,which could be broken by chilling and dry storage,especially long-term dry storage.Achene germination of the two semi-shrubs preferred lower temperature fluctuation (10 to 22oC) and was not sensitive to light.But the two annuals preferred higher temperature fluctuation (34 to 22oC) and strong light for their achene germination.These four Artemisia species showed similar responses to sand burial,i.e.soil surface was most favorable for seedling emergence,and the deeper the sand burial,the fewer the seedling emergence.For the two semi-shrubs,their microhabitats are sand dunes with high temperature and intense light,which are not favorable for germination and seedling survival.Only rainfall contributes to temporary decrease of temperature and then triggers germination.We deduced that germination is not the main but a supplementary reproductive mode for the two semi-shrubs in sand dunes.For the two annuals,achene germination is the only reproductive mode,but different responses have been developed for microhabitat adaptation.For A.sieversiana,high germination capacities in wide temperature ranges and all light conditions could improve its competition and advancement in the wettest microhabitats.For A.scoparia,obvious innate dormancy of fresh achenes and germination inhabitation under unfavorable conditions are important adaptation to environmental disturbances. | XueHua LI DeMing JIANG Alamusa QuanLai ZHOU Toshio OSHIDA | 2012 | Journal of Arid Land2012，4，1： | 3 |
| 8 | The return and loss of litter phosphorus in different types of sand dunes in Horqin Sandy Land,northeastern China显示文摘Litter phosphorus(P) return is important to maintain the P cycle and balance in the sandy land of arid areas.In this study,we determined the loss and return of litter P in sand dune areas and elucidated their relationship.We investigated litter production and litter P amount,and simulated leaf litter moving dynamics to understand the relationships between the loss of litter P and the total litter P,and between the return of litter P and the total litter P in active(AD),semi-stabilized(SSD) and stabilized(SD) dunes in Inner Mongolia,northeastern China.The vegetation litter P was 12.6,94.5,and 201.6 mg P/m2 in AD,SSD,and SD,respectively.A significant movement and loss of leaf litter P with time occurred on the three types of sand dunes.As a result,the loss of P was 7.4,46.9,and 69.8 mg P/m2 and the return of P was 5.5,47.6,and 131.8 mg P/m2 in AD,SSD,and SD,respectively.The relationship between both loss and return of P and total litter P in AD,SSD,and SD was revealed by linear regression.The slope of the regression line indicated the rate of loss or return of litter P.From AD to SD,the loss rate showed a declining slope(0.52,0.32,and 0.17 for AD,SSD,and SD,respectively),and the return rate showed a rising slope(0.48,0.67,and 0.83 for AD,SSD,and SD,respectively).The loss of litter P should be regarded in the local management of vegetation and land in sand dune areas.Improved vegetation restoration measures are necessary to decrease litter P loss to maintain the stability of ecosystems in sand dune areas. | QuanLai ZHOU DeMing JIANG ZhiMin LIU Alamusa XueHua LI YongMing LUO HongMei WANG | 2012 | Journal of Arid Land2012，4，4： | 3 |
| 9 | Some Classes of Disconnected Antimagic Graphs and Their Joins显示文摘A labeling of a graph G is a bijection from E(G) to the set {1,2,…,|E (G)| }.A labeling is antimagic if for any distinct vertices x and y,the sum of the labels on edges incident to x is different from the sum of the labels on edges incident to y.We say that a graph is antimagic if it has an antimagic labeling.Hartsfield and Ringel conjectured in 1990 that every graph other than 2 K is antimagic.In this paper,we show that the antimagic conjecture is false for the case of disconnected graphs.Furthermore,we find some classes of disconnected graphs that are antimagic and some classes of graphs whose complement are disconnected are antimagic. | WANG Tao LIU Mingju LI Deming | 2012 | Wuhan University Journal of Natural Sciences2012，17，3： | 3 |
| 10 | Spatial heterogeneity of plant species on the windward slope of active sand dunes in a semi-arid region of China显示文摘Species richness and abundance are two important species diversity variables that have attracted particular attention because of their significance in determining present and future species composition conditions.This paper aims to explain the qualitative and quantitative relationships between species diversity pattern and grain size(i.e.size of the sampling unit),and species diversity pattern and sampling area,and to analyze species diversity variability on active sand dunes in the Horqin Sandy Land,northeastern Inner Mongolia,China.A 50 m×50 m sampling plot was selected on the windward slope,where the dominant species was annual herb Agriophyllum squarrosum.Species composition and abundance at five grain sizes were recorded,and the species-area curves were produced for thirteen grain sizes.The range of values for species abundance tended to increase with increasing grain size in the study area,whereas,generally,species richness did not follow this rule because of poor species richness on the windward slope of active sand dunes.However,the homogeneity of species richness increased significantly.With the increase in sampling area,species abundance increased linearly,but richness increased logarithmically.Furthermore,variograms showed that species diversity on the windward slope of active sand dunes was weakly anisotropic and the distribution pattern was random,according to the Moran Coefficient.The results also showed that species richness was low,with a random distribution pattern.This conflicts with the results of previous studies that showed spatial aggregation in lower richness in a sampling area within a community and inferred that the physical processes play a more important role in species diversity than distribution pattern on active sand dunes.Further research into different diversity patterns and mechanisms between active sand dunes and interdune lowlands should be conducted to better understand biodiversity conservation in sand dune fields. | DeMing JIANG ChunPing MIAO XueHua LI XiaoLan LI ALAMUSA QuanLai ZHOU | 2013 | Journal of Arid Land2013，5，1： | 3 |
| 11 | Vibration Deformation Monitoring of Offshore Wind Turbines Based on GBIR显示文摘In view of the disadvantages of vibration safety monitoring technology for offshore wind turbines,a new method is proposed to obtain deformation information of towering and dynamic targets in real-time by the ground-based interferometric ra-dar(GBIR).First,the working principle and unique advantages of the GBIR system are introduced.Second,the offshore wind turbines in Rongcheng,Shandong Province are selected as the monitoring objects for vibration safety monitoring,and the GPRI-II portable radar interferometer is used for the health diagnosis of these wind turbines.Finally,the interpretation method and key processing flow of data acquisition are described in detail.This experiment shows that the GBIR system can accurately identify the millimeter-scale vibration deformation of offshore wind turbines and can quickly obtain overall time series deformation images of the target bodies,which demonstrate the high-precision deformation monitoring ability of the GBIR technology.The accuracy meets the requirements of wind turbine vibration monitoring,and the method is an effective spatial deformation monitoring means for high-rise and dynamic targets.This study is beneficial for the further enrichment and improvement of the technical system of wind turbine vibration safety monitoring in China.It also provides data and technical support for offshore power engineering management and control,health diagnosis,and disaster prevention and mitigation. | MA Deming LI Yongsheng LIU Yanxiong CAI Jianwei ZHAO Rui | 2021 | Journal of Ocean University of China2021，20，3： | 2 |

| 13 | A direct real-time polymerase chain reaction assay for rapid high-throughput detection of highly pathogenic North American porcine reproductive and respiratory syndrome virus in China without RNA purification显示文摘Background:Porcine reproductive and respiratory syndrome virus(PRRSV),and particularly its highly pathogenic genotype(HP-PRRSV),have caused massive economic losses to the global swine industry.Results:To rapidly identify HP-PRRSV,we developed a direct real-time reverse transcription polymerase chain reaction method(dRT-PCR) that could detect the virus from serum specimen without the need of RNA purification.Our dRT-PCR assay can be completed in 1.5 h from when a sample is received to obtaining a result.Additionally,the sensitivity of dRT-PCR matched that of conventional reverse transcription PCR(cRT-PCR) that used purified RNA.The lowest detection limit of HP-PRRSV was 6.3 TCID_(50) using dRT-PCR.We applied dRT-PCR assay to 144 field samples and the results showed strong consistency with those obtained by cRT-PCR.Moreover,the dRT-PCR method was able to tolerate 5-20%(v/v) serum.Conclusions:Our dRT-PCR assay allows for easier,faster,more cost-effective and higher throughput detection of HP-PRRSV compared with cRT-PCR methods.To the best of our knowledge,this is the first report to describe a real-time RT-PCR assay capable of detecting PRRSV in crude serum samples without the requirement for purifying RNA.We believe our approach has a great potential for application to other RNA viruses. | Kang Kang Keli Yang Jiasheng Zhong Yongxiang Tian Limin Zhang Jianxin Zhai Li Zhang Changxu Song Christine Yuan Gou Jun Luo Deming Gou | 2015 | Journal of Animal Science and Biotechnology2015，6，1： | 2 |

| 15 | An improved Tet-on system in micro RNA overexpression and CRISPR/Cas9-mediated gene editing显示文摘Background: Tetracycline(Tet)-regulated expression system has become a widely applied tool to control gene activity. This study aimed to improve the Tet-on system with superior regulatory characteristics.Results: By comprehensively comparing factors of transactivators, Tet-responsive elements(TREs), orientations of induced expression cassette, and promoters controlling the transactivator, we developed an optimal Tet-on system with enhanced inducible efficiency and lower leakiness. With the system, we successfully performed effective inducible and reversible expression of micro RNA, and presented a more precise and easily reproducible fine-tuning for confirming the target of a mi RNA. Finally, the system was applied in CRISPR/Cas9-mediated knockout of nuclear factor of activated T cells-5(NFAT5), a protective transcription factor in cellular osmoregulation.Conclusions: This study established an improved Tet-on system for powerful and stringent gene regulation in functional genetic studies. | Kang Kang Lian Huang Qing Li Xiaoyun Liao Quanjin Dang Yi Yang Jun Luo Yan Zeng Li Li Deming Gou | 2019 | Journal of Animal Science and Biotechnology2019，10，4： | 2 |
| 16 | Spatial structure and species composition of soil seed banks in moving sand dune systems of northeast China显示文摘Soil seed banks can provide a mechanistic for understanding the recruitment dynamics and can inform conservation management of ecosystems. To investigate the contribution of soil seed banks to vegetation restoration in moving sand dune systems, we compared seed structure and species similarity between soil seed banks and standing vegetation among moving sand dunes, ecotones and dune slacks in northeast China. Average seed density in dune slacks was greater than in ecotones or moving sand dunes.Seed density in the soil layer of 0–10 cm was greater than at 10–20 cm both in the moving sand dunes and the ecotones, but seed densities were similar at depths of 10–20and 20–30 cm in moving sand dunes. Moreover, the spatial autocorrelation of seed density on moving sand dunes was weak but was strong on the ecotones and dune slacks. The species in the soil seed bank of moving sand dune systems were nearly all annuals, and the low similarity was mainly due to the lack of perennial species that were common in standing vegetation. Consequently, vegetation restoration cannot mainly rely on the soil seed banks in the movingsand dunes and more attention should be paid to protection of the dune slacks because they are the main source of seed disperse and seedling recruitment in moving sand dune systems. | Chunping Miao Xuehua Li Meiyu Jia Xu Han Deming Jiang | 2016 | Journal of Forestry Research2016，27，1： | 2 |
| 17 | On-chip cyclic-AWG-based 12 × 12 silicon wavelength routing switches with minimized port-to-port insertion loss fluctuation显示文摘With the rapidly increasing bandwidth requirements of optical communication networks, compact and low-cost large-scale optical switches become necessary. Silicon photonics is a promising technology due to its small footprint, cost competitiveness, and high bandwidth density. In this paper, we demonstrate a 12 × 12 silicon wavelength routing switch employing cascaded arrayed waveguide gratings(AWGs) connected by a silicon waveguide interconnection network on a single chip. We optimize the connecting strategy of the crossing structure to reduce the switch's footprint. We develop an algorithm based on minimum standard deviation to minimize the port-toport insertion loss(IL) fluctuation of the switch globally. The simulated port-to-port IL fluctuation decreases by about 3 dB compared with that of the conventional one. The average measured port-to-port IL is 13.03 dB, with a standard deviation of 0.78 dB and a fluctuation of 2.39 dB. The device can be used for wide applications in core networks and data centers. | ZEPENG PAN SONGNIAN FU LULUZI LU DONGYU LI WEIJIE CHANG DEMING LIU MINMING ZHANG | 2018 | Photonics Research2018，6，5： | 2 |
