1Effects of riparian vegetation patterns on the distribution and potential loss of soil nutrients: a case study of the Wenyu River in Beijing显示文摘一个河边的生态系统是在一条河隧道和陆上的生态系统之间的一个生态的转变地区。河边的生态系统在维持溪流健康和银行稳定起一个重要作用。因为人的活动,河边的植被的类型沿着 Wenyu 河极大地变化了。这研究由于土壤营养素损失在水污染上检验河边的植被模式的影响。到高地的来自河隧道的四个河边的植被模式被选择为这研究的焦点:草地,农田,草地农田,和 grassland-manmade 草坪。沿着植被模式和滋养的损失的潜在的风险的土壤营养素的不同分布被观察并且比较。结果证明河边的农田有全部的氮(TN ) 的最低价值,全部的磷(TP ) ,可得到的氮(一) ,可得到的磷(AP ) ,和有机物(OM ) ,但是它有最高的土壤体积密度(BD ) 。土壤 TN 的分布, TP,一, AP,和 OM 为河边的农田向河隧道从高地展出了一个衰退趋势,而一个不同趋势为河边的草地被观察。草地农田和 grassland-manmade 草坪的植被模式证明在更低的斜坡的草地有更多的营养素和 OM,但是在上面的斜坡比农田或 manmade 草坪降低土壤 BD。那么,降低斜坡的草地可以从高地拦截并且渗透表面流量。降低斜坡的草地有土壤 TN 的高水平, TP,一,并且 AP,并且因此,它可以成为滋养的损失的新来源。我们的结果建议河边的植被的管理应该被改进,特别地在浓密地占据的区域,到控制土壤侵蚀和河污染。Erhui GUO Liding CHEN Ranhao SUN Zhaoming WANG 2015Frontiers of Environmental Science & Engineering2015,9,2:6
2Challenges and strategies in high-accuracy manufacturing of the world’s largest SiC aspheric mirror显示文摘In the process of manufacturing the world’s largest silicon carbide(SiC)aspheric mirror,the primary difficulties are mirror blank preparation,asphere fabrication,and testing,as well as cladding and coating.Specifically,the challenges include the homogeneity of the complicated structure casting,accuracy and efficiency of the fabrication process,print-through effect,fidelity and precision of test procedure,stress and denseness of cladding process,the dynamic range of interferometric measurement,and air turbulence error due to the long optical path.To break through such a barrier of difficulties,we proposed the water-soluble room temperature vanishing mold and gel casting technology,homogeneous microstructure reaction-formed joint technology,nano-accuracy efficient compound fabrication,gravity unloading technology,high-denseness low-defect physical vapor deposition(PVD)Si-cladding technology,test data fusion method,and time-domain averaging method,etc.Based on the proposed technologies and methods,we have accomplished the world’s largest SiC aspheric mirror with a size of φ4.03 m.The impressive performance of the SiC aspheric mirror is validated by the characteristics of the fabricated SiC aspheric mirror.The aerial density of the SiC blank is less than 120 kg/m^(2),surface shape test accuracy is better than 6 nm RMS,thickness inhomogeneity of the cladding layer is less than 5%,and the final surface figure error and roughness are 15.2 nm RMS and 0.8 nm RMS,respectively.Xuejun Zhang Haixiang Hu Xiaokun Wang Xiao Luo Ge Zhang Wenxing Zhao Xiaoyi Wang Zhenyu Liu Ling Xiong Erhui Qi Congcong Cui Yanchao Wang Yingjie Li Xu Wang Longxiang Li Yang Bai Qiang Cheng Zhiyu Zhang Ruigang Li Wa Tang Xuefeng Zeng Weijie Deng Feng Zhang 2022Light(Science & Applications)2022,11,12:3
3Spatial variation in grain-size population of surface sediments from northern Bering Sea and western Arctic Ocean: Implications for provenance and depositional mechanisms显示文摘In general,sediments in nature comprise populations of various diameters.Accurate information regarding the sources and depositional mechanisms of the populations can be obtained through their temporal and spatial comparisons.In this study,the grain size distribution of surface sediments from the Bering Sea and western Arctic Ocean were fitted and partitioned into populations using a log-normal distribution function.The spatial variations in the populations indicate differences in their sources and deposition mechanisms.The sediments on most of the Bering Sea Shelf originated from the Yukon River,and were transported westward by waves and currents.However,the presence of a coarser population outside Anadyr Bay was the result of Anadyr River transport.Additionally,a northward transport trend of fine suspended particles was observed on the west side of the Bering Sea Shelf.The sediments in Hope Valley in the south Chukchi Sea also originated from the Yukon River.The coarser population on the central Chukchi Sea Shelf originated from coast of Alaska to the east,not the Yukon River,and was transported by sea ice and bottom brine water.The populations of sediments from the Chukchi Basin and the base of the Chukchi Sea Slope are the result of sea ice and eddy action.Surface sediments from the western high Arctic Ocean predominantly comprised five populations,and two unique populations with mode diameters of 50–90μm and 200–400μm,respectively,were ubiquitous in the glacial and interglacial sediments.It was difficult to distinguish whether these two populations originated from sea ice or icebergs.Therefore,caution should be exercised when using either the>63μm or>250μm fractions in sediments as a proxy index for iceberg and ice sheet variation in the high Arctic Ocean.WANG Weiguo YANG Jichao ZHAO Mengwei DONG Linsen JIANG Min HUANG Erhui 2020Advances in Polar Science2020,31,3:2
4Heat Transfer and Flow Resistance Characteristics of Helical Baffle Heat Exchangers with Twisted Oval Tube显示文摘To overcome the defect of the significant increase in pressure drop when the heat transfer performance of helical baffle heat exchanger is improved,a novel helical baffle heat exchanger with twisted oval tube is proposed.Numerical simulation was done to exhibit the shell side heat transfer and flow characteristics with CFD software Fluent.The field synergy principle was used to evaluate the shell side performance.The results show that the flow velocity distribution on the shell side of the spiral baffle heat exchanger is more uniform and the velocity near the tube wall increases in the range of research parameters,as the circular tube is replaced by a twisted elliptical tube with the same perimeter length.Moreover,the helical baffle heat exchanger with twisted oval tube has better field synergy of velocity and temperature gradient,velocity and pressure gradient.The helical baffle heat exchanger with helix angle of 15°has better performance than that of circular tube,and its heat transfer coefficient is improved about 3.3%and pressure drop is reduced by 17.1%–19.1%.Hence,the comprehensive heat transfer performance is improved by 21.5%–22.5%.When the helix angle is 20°,the comprehensive heat transfer performance is increased by 16.1%–18.0%with heat transfer coefficient improvement of 3.6%and pressure drop reduction of 13.9%–16.5%.GU Xin ZHENG Zhiyang XIONG Xiaochao JIANG Erhui WANG Tongtong ZHANG Dongwei 2022Journal of Thermal Science2022,31,2:2
5Formyl tetrahydrofolate deformylase affects hydrogen peroxide accumulation and leaf senescence by regulating the folate status and redox homeostasis in rice显示文摘It is well established that an abnormal tetrahydrofolate(THF)cycle causes the accumulation of hydrogen peroxide(H_(2)O_(2))and leaf senescence,however,the molecular mechanism underlying this relationship remains largely unknown.Here,we reported a novel rice tetrahydrofolate cycle mutant,which exhibited H_(2)O_(2)accumulation and early leaf senescence phenotypes.Map-based cloning revealed that HPA1 encodes a tetrahydrofolate deformylase,and its deficiency led to the accumulation of tetrahydrofolate,5-formyl tetrahydrofolate and 10-formyl tetrahydrofolate,in contrast,a decrease in 5,10-methenyl-tetrahydrofolate.The expression of tetrahydrofolate cycle-associated genes encoding serine hydroxymethyl transferase,glycine decarboxylase and 5-formyl tetrahydrofolate cycloligase was significantly down-regulated.In addition,the accumulation of H_(2)O_(2)in hpa1 was not caused by elevated glycolate oxidation.Proteomics and enzyme activity analyses further revealed that mitochondria oxidative phosphorylation complex I and complex V were differentially expressed in hpa1,which was consistent with the H_(2)O_(2)accumulation in hpa1.In a further feeding assay with exogenous glutathione(GSH),a non-enzymatic antioxidant that consumes H_(2)O_(2),the H_(2)O_(2)accumulation and leaf senescence phenotypes of hpa1 were obviously compensated.Taken together,our findings suggest that the accumulation of H_(2)O_(2)in hpa1 may be mediated by an altered folate status and redox homeostasis,subsequently triggering leaf senescence.Erhui Xiong Guojun Dong Fei Chen Chen Zhang Shan Li Yanli Zhang Jahidul Islam Shohag Xiaoe Yang Yihua Zhou Qian Qian Limin Wu Yanchun Yu 2021Science China(Life Sciences)2021,64,5:1

9Effects of typhoon 'KAI-TAK' on deep ocean ambient noise in the South China Sea显示文摘By investigating the effects on deep ocean ambient noise of typhoon 'KAI-TAK' which passed the north area of the South China Sea,it is shown that the wind speed,the rainfall intensity and the long wave swell caused by typhoon affect the ocean ambient noise significantly.The correlation between the ocean ambient noise and the wind speed during the typhoon is much better than that in the non-typhoon period in the same Beaufort scale.Analysis of the correlation between the 415 h ocean ambient noise measured data and wind speed shows that,when the frequency is greater than 300 Hz,the correlation coefficient between the ocean ambient noise and the wind speed is greater than 0.5,achieving a moderate correlation;when the frequency is greater than 630 Hz,the correlation coefficient is between 0.8 and 0.9,achieving a high degree of correlation.The correlation between the ocean ambient noise and the wind speed is better than that between the ocean ambient noise and the significant wave height when the frequency is greater than 300 Hz.The correlation between the ocean ambient noise and the wind speed in infrasonic band from 10 Hz to 20 Hz is poor in the South China Sea,because the shipping is busy in this sea area and the ocean ambient noise is contaminated by the ship noise even during the typhoon.WEN Hongtao YANG Yanming WANG Ning RUAN Hailin HUANG Erhui 2017Chinese Journal of Acoustics2017,36,2:1

12Visible-light-driven photocatalytic degradation of rhodamine B using Bi_(2)WO_(6)/GO deposited on polyethylene terephthalate fabric显示文摘The environmental repercussions of wastewater from the dye process mean that it is very important to obtain an eco-friendly photocatalyst that would degrade wastewater.Herein,bismuth tungstate/graphene oxide(Bi_(2)WO_(6)/GO)composites are fabricated through in-situ hydrothermal reaction and then the Bi_(2)WO_(6)/GO photocatalysts are deposited onto polyethylene terephthalate(PET)fabric.The obtained Bi_(2)WO_(6)/GO deposited PET fabrics are then characterized through XPS,Raman,SEM,TEM,XRD,UV-vis,BET method and photoluminescence spectroscopy(PL)to investigate their chemical and crystal structures,morphology,optical property,surface area and photochemical properties.Photocatalytic performance is studied through examining the rate of degrading rhodamine B(RhB)under visible light.Surface of PET fibers is densely covered with Bi_(2)WO_(6)/GO.Bi_(2)WO_(6)/GO deposited PET fabrics show a broad absorption band in the visible spectra.Removal rate of RhB on the Bi_(2)WO_(6)/GO deposited PET fabric is the highest with the GO content of 2 g/L(labeled as Bi_(2)WO_(6)/2 g/LGO).The result of active species experiment shows that superoxide radicals(·O_(2)^(−))plays a major role in the degradation of RhB.Moreover,Bi_(2)WO_(6)/2 g/LGO deposited PET fabric shows excellent cycle stability of photocatalytic degradation for RhB.The findings in this work can be extended to preparation other types of composite on the textile for photocatalysis,which can be applied to remove dyes in the wastewater produced by the textile or leather industry.Zoufei Du Ce Cui Sihang Zhang Hongyan Xiao Erhui Ren Ronghui Guo Shouxiang Jiang 2020Journal of Leather Science and Engineering2020,2,1:1
13Machine learning of synaptic structure with neurons to promote tumor growth显示文摘In this paper,we use machine learning techniques to form a cancer cell model that displays the growth and promotion of synaptic and electrical signals.Here,such a technique can be applied directly to the spiking neural network of cancer cell synapses.The results show that machine learning techniques for the spiked network of cancer cell synapses have the powerful function of neuron models and potential supervisors for different implementations.The changes in the neural activity of tumor microenvironment caused by synaptic and electrical signals are described.It can be used to cancer cells and tumor training processes of neural networks to reproduce complex spatiotemporal dynamics and to mechanize the association of excitatory synaptic structures which are between tumors and neurons in the brain with complex human health behaviors.Erhui WANG Xuelan ZHANG Liancun ZHENG Chang SHU 2020Applied Mathematics and Mechanics(English Edition)2020,41,11:0
14New insights into the unfolded protein response(UPR)-anterior gradient 2(AGR2)pathway in the regulation of intestinal barrier function in weaned piglets显示文摘Sustained dysfunction of the intestinal barrier caused by early weaning is a major factor that induces postweaning diarrhea in weaned piglets.In both healthy and diseased states,the intestinal barrier is regulated by goblet cells.Alterations in the characteristics of goblet cells are linked to intestinal barrier dysfunction and inflammatory conditions during pathogenic infections.In this review,we summarize the current understanding of the mechanisms of the unfolded protein response(UPR)and anterior gradient2(AGR2)in maintaining intestinal barrier function and how modifications to these systems affect mucus barrier characteristics and goblet cell dysregulation.We highlight a novel mechanism underlying the UPR-AGR2 pathway,which affects goblet cell differentiation and maturation and the synthesis and secretion of mucin by regulating epidermal growth factor receptor and mucin 2.This study provides a theoretical basis and new insights into the regulation of intestinal health in weaned piglets.Feng Zhang Mengxian Chen Xiaodan Liu Xu Ji Shenghe Li Erhui Jin 2023Animal Nutrition2023,,4:0
15Cancer cells corrupt normal epithelial cells through miR-let-7c-rich small extracellular vesicle-mediated downregulation of p53/PTEN显示文摘Tumor volume increases continuously in the advanced stage, and aside from the self-renewal of tumor cells, whether the oncogenic transformation of surrounding normal cells is involved in this process is currently unclear. Here, we show that oral squamous cell carcinoma(OSCC)-derived small extracellular vesicles(s EVs) promote the proliferation, migration, invasion, and epithelial-mesenchymal transition(EMT) of normal epithelial cells but delay their apoptosis. In addition, nuclear-cytoplasmic invaginations and multiple nucleoli are observed in s EV-treated normal cells, both of which are typical characteristics of premalignant lesions of OSCC. Mechanistically, mi Rlet-7c in OSCC-derived s EVs is transferred to normal epithelial cells, leading to the transcriptional inhibition of p53 and inactivation of the p53/PTEN pathway. In summary, we demonstrate that OSCC-derived s EVs promote the precancerous transformation of normal epithelial cells, in which the mi R-let-7c/p53/PTEN pathway plays an important role. Our findings reveal that cancer cells can corrupt normal epithelial cells through s EVs, which provides new insight into the progression of OSCC.Weilian Liang Yang Chen Hanzhe Liu Hui Zhao Tingting Luo Hokeung Tang Xiaocheng Zhou Erhui Jiang Zhe Shao Ke Liu Zhengjun Shang 2022International Journal of Oral Science2022,14,4:0
16AtMYBS1 negatively regulates heat tolerance by directly repressing the expression of MAX1 required for strigolactone biosynthesis in Arabidopsis显示文摘Heat stress caused by global warming requires the development of thermotolerant crops to sustain yield.It is necessary to understand the molecular mechanisms that underlie heat tolerance in plants.Strigolactones(SLs)are a class of carotenoid-derived phytohormones that regulate plant development and responses to abiotic or biotic stresses.Although SL biosynthesis and signaling processes are well established,genes that directly regulate SL biosynthesis have rarely been reported.Here,we report that the MYB-like transcription factor AtMYBS1/AtMYBL,whose gene expression is repressed by heat stress,functions as a negative regulator of heat tolerance by directly inhibiting SL biosynthesis in Arabidopsis.Overexpression of AtMYBS1 led to heat hypersensitivity,whereas atmybs1 mutants displayed increased heat tolerance.Expression of MAX1,a critical enzyme in SL biosynthesis,was induced by heat stress and downregulated in AtMYBS1-overexpression(OE)plants but upregulated in atmybs1 mutants.Overexpression of MAX1 in the AtMYBS1-OE background reversed the heat hypersensitivity of AtMYBS1-OE plants.Loss of MAX1 function in the atmyb1 background reversed the heat-tolerant phenotypes of atmyb1 mutants.Yeast one-hybrid assays,chromatin immunoprecipitation‒qPCR,and transgenic analyses demonstrated that AtMYBS1 directly represses MAX1 expression through the MYB binding site in the MAX1 promoter in vivo.The atmybs1d14 double mutant,like d14 mutants,exhibited hypersensitivity to heat stress,indicating the necessary role of SL signaling in AtMYBS1-regulated heat tolerance.Our findings provide new insights into the regulatory network of SL biosynthesis,facilitating the breeding of heat-tolerant crops to improve crop production in a warming world.Xiang Li Jianhua Lu Xuling Zhu Yanqi Dong Yanli Liu Shanshan Chu Erhui Xiong Xu Zheng Yongqing Jiao 2023Plant Communications2023,4,6:0
