| 1 | Assessment of the relative role of climate change and human activities in desertification:显示文摘Climate change and human activities are the two kinds of driving forces in desertification,and assessing their relative role in desertification is of great significance to deeply understanding the driving mechanisms and preventing desertification expansion.This paper has systematically reviewed the progress of the researches on assessing the relative role of climate change and human activities in desertification from qualitative,semi-quantitative and quantitative aspects respectively.The authors found that there were still some problems in the previous researches.For example,the subjectivity in assessment was obvious,the assessment cannot be easily repeated,and the assessment and its results were always based on administrative regions and less taken and expressed in a continuous space.According to the progress of previous researches and the works conducted by the authors recently,we put forward a quantitative approach by selecting NPP as a common indicator to measure the relative role of climate change and human activities in desertification and dividing the ecological process of 'driving force effect-dynamic response of desertified land' into several scenarios.Meanwhile,validation and scale of assessment should be taken into account when quantitative assessment of the relative role of climate change and human activities in desertification are carried out. | XU Duanyang LI Chunlei ZHUANG Dafang PAN Jianjun | 2011 | Journal of Geographical Sciences2011,21,5: | 16 |

| 6 | Temperature and NaCl deposition dependent corrosion of SAC305 solder alloy in simulated marine atmosphere显示文摘The stable operation of electronic devices in marine atmospheric environment is affected by the corrosion deterioration of solder joints,and the effects by atmosphere temperature and chloride deposition are critical.In this work,NaCl deposition and temperature dependent corrosion of Pb-free SAC305 solder in simulated marine atmosphere has been investigated.The results indicate that higher NaCl deposition prolongs the surface wetting time and leads to the final thicker saturated electrolyte film for further corrosion.Higher temperature accelerates the evaporation and contributes to the final thinner saturated NaCl electrolyte film.Besides,the corrosion control process varies under the initially covered thicker NaCl electrolyte layer and under the final saturated much thinner NaCl electrolyte film as the evaporation proceeds.Moreover,the ready oxygen availability through the final thinner saturated NaCl electrolyte film facilitates the formation of corrosion product layer mainly of electrochemically stable SnO2,but higher temperature leads to the final corrosion product layer with smaller crystal size and large cracks.The findings clearly demonstrate the effects of NaCl deposition and temperature on corrosion evolution of SAC305 solder joints and are critical to the daily maintenance of electronic devices for longer service life in marine atmosphere. | Chuang Qiao Mingna Wang Long Hao Xiahe Liu Xiaolin Jiang Xizhong An Duanyang Li | 2021 | Journal of Materials Science & Technology2021,,16: | 3 |
| 7 | Assessing the relative role of climate change and human activities in desertification of North China from 1981 to 2010显示文摘Desertification is a severe environmental problem induced by both climate change and human activities.This study assessed the relative contribution of climate change,human activities,and different climatic and anthropogenic factors in desertification reversion and expansion of North China from 1981 to 2010.The results showed that the desertification of North China had changed significantly over the past 30 years;desertification reversion and expansion covered an area of 750,464 km^2, and the spatial distribution of these regions exhibited considerable heterogeneity.For desertification reversion, climate change and human activity accounted for 22.6% and 26%,respectively of total reverted land.Wind speed reduction and the improvement ofhydrothermal conditions were the most important climatic factors for desertification reversion in the arid region of Northwest China (ARNC) and the Three-River Headwaters region (TRHR),and the reduction in grassland use intensity was the most important anthropogenic factor related to desertification reversion in Inner Mongolia and regions along the Great Wall (IMGW). For desertification expansion,the relative role of climate change was more obvious,which was mainly attributed to the continuous reduction in precipitation in eastern IMGW, and the increase in grassland use intensity was the main factor underlying regional human-induced desertification expansion. | Duanyang XU Alin SONG Dajing LI Xue DING Ziyu WANG | 2019 | Frontiers of Earth Science2019,13,1: | 2 |
| 8 | Porous Y_2SiO_5 Ceramic with Low Thermal Conductivity显示文摘Porous Y2SiO5 ceramic was fabricated by freeze casting with tert-butyl alcohol as solvent. The porous Y2SiO5 ceramic possessed long straight pore structure. With decreasing solid loading from 20 to 10 vol.%, the porosity of the Y2SiO5 ceramic increased linearly from 45% to 72%, while the compressive strength declined from 23.2 to 3.1MPa. The thermal conductivity of Y2SiO5 decreased from 1.34W/mK for the dense bulk to 0.05 W/mK for the porous body with a porosity of 57%. | Duanyang Li Meishuan Li | 2012 | Journal of Materials Science & Technology2012,28,9: | 2 |
| 9 | Sinoatrial node pacemaker cells share dominant biological properties with glutamatergic neurons显示文摘Activation of the heart normally begins in the sinoatrial node(SAN).Electrical impulses spontaneously released by SAN pacemaker cells(SANPCs)trigger the contraction of the heart.However,the cellular nature of SANPCs remains controversial.Here,we report that SANPCs exhibit glutamatergic neuron-like properties.By comparing the single-cell transcriptome of SANPCs with that of cells from primary visual cortex in mouse,we found that SANPCs co-clustered with cortical neurons.Tissue and cellular imaging confirmed that SANPCs contained key elements of glutamatergic neurotransmitter system,expressing genes encoding glutamate synthesis pathway(G/s),ionotropic and metabotropic glutamate receptors(Grina,Gria3,Grm1 and Grm5)t and glutamate transporters(Slc17a7).SANPCs highly expressed cell markers of glutamatergic neurons(Snap25 and S/-c17a7)t whereas Gad1,a marker of GABAergic neurons,was negative.Functional studies revealed that inhibition of glutamate receptors or transporters reduced spontaneous pacing frequency of isolated SAN tissues and spontaneous Ca2+transients frequency in single SANPC.Collectively,our work suggests that SANPCs share dominant biological properties with glutamatergic neurons,and the glutamatergic neurotransmitter system may act as an intrinsic regulation module of heart rhythm,which provides a potential intervention target for pacemaker cell-associated arrhythmias. | Dandan Liang Zhigang Xue Jinfeng Xue Duanyang Xie Ke Xiong Huixing Zhou Fulei Zhang Xuling Su Guanghua Wang Qicheng Zou Yi Liu Jian Yang Honghui Ma Luying Peng Chunyu Zeng Gang Li Li Wang Yi-Han Chen | 2021 | Protein & Cell2021,12,7: | 1 |

| 12 | Homoepitaxial growth of (100) Si-doped β-Ga_(2)O_(3) films via MOCVD显示文摘Homoepitaxial growth of Si-doped β-Ga_(2)O_(3) films on semi-insulating(100) β-Ga_(2)O_(3) substrates by metalorganic chemical vapor deposition(MOCVD) is studied in this work. By appropriately optimizing the growth conditions, an increasing diffusion length of Ga adatoms is realized, suppressing 3D island growth patterns prevalent in(100) β-Ga_(2)O_(3) films and optimizing the surface morphology with [010] oriented stripe features. The slightly Si-doped β-Ga_(2)O_(3) film shows smooth and flat surface morphology with a root-mean-square roughness of 1.3 nm. Rocking curves of the(400) diffraction peak also demonstrate the high crystal quality of the Si-doped films. According to the capacitance–voltage characteristics, the effective net doping concentrations of the films are 5.41 × 10~(15) – 1.74 × 10~(20) cm~(-3). Hall measurements demonstrate a high electron mobility value of 51cm~2/(V·s), corresponding to a carrier concentration of 7.19 × 10~(18) cm~(-3) and a high activation efficiency of up to 61.5%. Transmission line model(TLM) measurement shows excellent Ohmic contacts and a low specific contact resistance of 1.29 × 10~(-4) Ω·cm~2 for the Si-doped film, which is comparable to the Si-implanted film with a concentration of 5.0 × 10~(19) cm~(-3), confirming the effective Si doing in the MOCVD epitaxy. | Wenbo Tang Xueli Han Xiaodong Zhang Botong Li Yongjian Ma Li Zhang Tiwei Chen Xin Zhou Chunxu Bian Yu Hu Duanyang Chen Hongji Qi Zhongming Zeng Baoshun Zhang | 2023 | Journal of Semiconductors2023,44,6: | 0 |
| 13 | A telomere-to-telomere reference genome provides genetic insight into the pentacyclic triterpenoid biosynthesis in Chaenomeles speciosa显示文摘Chaenomeles speciosa(2n=34),a medicinal and edible plant in the Rosaceae,is commonly used in traditional Chinese medicine.To date,the lack of genomic sequence and genetic studies has impeded efforts to improve its medicinal value.Herein,we report the use of an integrative approach involving PacBio HiFi(third-generation)sequencing and Hi-C scaffolding to assemble a high-quality telomere-to-telomere genome of C.speciosa.The genome comprised 650.4 Mb with a contig N50 of 35.5 Mb.Of these,632.3 Mb were anchored to 17 pseudo-chromosomes,in which 12,4,and 1 pseudo-chromosomes were represented by a single contig,two contigs,and four contigs,respectively.Eleven pseudo-chromosomes had telomere repeats at both ends,and four had telomere repeats at a single end.Repetitive sequences accounted for 49.5%of the genome,while a total of 45515 protein-coding genes have been annotated.The genome size of C.speciosa was relatively similar to that of Malus domestica.Expanded or contracted gene families were identified and investigated for their association with different plant metabolisms or biological processes.In particular,functional annotation characterized gene families that were associated with the biosynthetic pathway of oleanolic and ursolic acids,two abundant pentacyclic triterpenoids in the fruits of C.speciosa.Taken together,this telomere-to-telomere and chromosome-level genome of C.speciosa not only provides a valuable resource to enhance understanding of the biosynthesis of medicinal compounds in tissues,but also promotes understanding of the evolution of the Rosaceae. | Shaofang He Duanyang Weng Yipeng Zhang Qiusheng Kong Keyue Wang Naliang Jing Fengfeng Li Yuebin Ge Hui Xiong Lei Wu De-Yu Xie Shengqiu Feng Xiaqing Yu Xuekui Wang Shaohua Shu Zhinan Mei | 2023 | Horticulture Research2023,10,10: | 0 |
| 14 | Hyper-gravity experiment of solute transport in fractured rock and evaluation method for long-term barrier performance显示文摘Hyper-gravity experiment enable the acceleration of the long-term transport of contaminants through fractured geological barriers.However,the hyper-gravity effect of the solute transport in fractures are not well understood.In this study,the sealed control apparatus and the 3D printed fracture models were used to carry out 1 g and N g hyper-gravity experiments.The results show that the breakthrough curves for the 1 g and N g experiments were almost the same.The differences in the flow velocity and the fitted hydrodynamic dispersion coefficient were 0.97–3.12%and 9.09–20.4%,indicating that the internal fractures of the 3D printed fracture models remained stable under hyper-gravity,and the differences in the flow and solute transport characteristics were acceptable.A method for evaluating the long-term barrier performance of low-permeability fractured rocks was proposed based on the hyper-gravity experiment.The solute transport processes in the 1 g prototype,1 g scaled model,and N g scaled model were simulated by the OpenGeoSys(OGS)software.The results show that the N g scaled model can reproduce the flow and solute transport processes in the 1 g prototype without considering the micro-scale heterogeneity if the Reynolds number(Re)critical Reynolds number(Recr)and the Peclet number(Pe)the critical Peclet number(Pecr).This insight is valuable for carrying out hyper-gravity experiments to evaluate the long-term barrier performance of low-permeability fractured porous rock. | Wenjie Xu Yingtao Hu Yunmin Chen Liangtong Zhan Ruiqi Chen Jinlong Li Duanyang Zhuang Qingdong Li Ke Li | 2023 | Rock Mechanics Bulletin2023,2,3: | 0 |
| 15 | Evaluating the performance of genomic selection on purebred population by incorporating crossbred data in pigs显示文摘Genomic selection(GS)has been widely used in livestock,which greatly accelerated the genetic progress of complex traits.The population size was one of the significant factors affecting the prediction accuracy,while it was limited by the purebred population.Compared to directly combining two uncorrelated purebred populations to extend the reference population size,it might be more meaningful to incorporate the correlated crossbreds into reference population for genomic prediction.In this study,we simulated purebred offspring(PAS and PBS)and crossbred offspring(CAB)base on real genotype data of two base purebred populations(PA and PB),to evaluate the performance of genomic selection on purebred while incorporating crossbred information.The results showed that selecting key crossbred individuals via maximizing the expected genetic relationship(REL)was better than the other methods(individuals closet or farthest to the purebred population,CP/FP)in term of the prediction accuracy.Furthermore,the prediction accuracy of reference populations combining PA and CAB was significantly better only based on PA,which was similar to combine PA and PAS.Moreover,the rank correlation between the multiple of the increased relationship(MIR)and reliability improvement was 0.60-0.70.But for individuals with low correlation(Cor(Pi,PA or B),the reliability improvement was significantly lower than other individuals.Our findings suggested that incorporating crossbred into purebred population could improve the performance of genetic prediction compared with using the purebred population only.The genetic relationship between purebred and crossbred population is a key factor determining the increased reliability while incorporating crossbred population in the genomic prediction on pure bred individuals. | Jun Zhou Qing Lin Xueyan Feng Duanyang Ren Jinyan Teng Xibo Wu Dan Wu Xiaoke Zhang Xiaolong Yuan Zanmou Chen Jiaqi Li Zhe Zhang Hao Zhang | 2024 | Journal of Integrative Agriculture2024,23,2: | 0 |

| 17 | Fault rupture propagation in soil with intercalation using nonlocal model and softening modulus modification显示文摘Fault rupture propagation is more complex in the overlying soil with intercalation than in homogeneous soil,and it is challenging to simulate this phenomenon accurately using the finite element method.To address this issue,an improved nonlocal model that incorporates softening modulus modification is proposed.The methodology has the advantage that the solutions are independent of both mesh sizes and characteristic lengths,while maintaining objective softening rates of materials.Using the proposed methodology,a series of numerical simulations are conducted to investigate the effects of different mechanical parameters,such as elastic modulus,friction angle and dilation angle of the soil within the intercalation,as well as the impact of geometries,such as the depth and thickness of the intercalation,on the fault rupture progress.This study not only provides significant insights into the mechanisms of fault rupture propagation,specifically in relation to intercalations,but also shows a great value in promoting the current research on fault rupture. | Jisen Shi Li Guan Duanyang Zhuang Xiang Chen Daosheng Ling | 2023 | Journal of Rock Mechanics and Geotechnical Engineering2023,15,11: | 0 |
