| 4 | Trehalose-6-phosphate phosphatase E modulates ABA-controlled root growth and stomatal movement in Arabidopsis显示文摘Trehalose plays important roles in plant growth and stress responses and is synthesized from trehalose-6-phosphate by trehalose-6-phosphate phosphatase(TPP).Here,we show that trehalose and abscisic acid(ABA)have synergistic effects on root growth and stomatal closure.The Arabidopsis thaliana genome contains ten genes encoding TPPs and the expression level of one,TPPE,and trehalose contents increased in response to ABA.In the pres-ence of ABA,the ABA-responsive transcription factor ABA RESPONSE ELEMENT BINDING FACTOR2(ABF2)directly binds to the TPPE promoter to activate its expression.Genetic analysis revealed that TPPE acts downstream of ABF2,which is supported by the findings that TPPE expression and trehalose content are reduced in the abf2 mutant and that a mutation in TPPE abolished the ABA-sensitive root elongation phenotype of 35S:ABF2 plants.Reactive oxygen spe-cies(ROS)accumulation in response to ABA failed to occur in tppe mutant plants,suggesting that TPPE is involved in ABA-controlled root elongation and sto-matal movement by inducing ROS accumulation.This study uncovers a new branch of the ABA signaling pathway and provides a molecular basis for the role of trehalose in plant responses to abiotic stress. | Wenjing Wang Qingbin Chen Shouming Xu Wen-Cheng Liu Xiaohong Zhu Chun-Peng Song | 2020 | Journal of Integrative Plant Biology2020，62，10： | 6 |
| 5 | Determination of full-scale pore size distribution of Gaomiaozi bentonite and its permeability prediction显示文摘Gaomiaozi(GMZ)bentonite is a potential buffer/backfill material for a deep geological disposal of highlevel radioactive waste.It has a wide pore size distribution(PSD)with sizes ranging from several nanometers to more than one hundred microns.Thus,properly characterizing the pore structures of GMZ bentonite is a challenging issue.In this study,pressure-controlled porosimetry(PCP),ratecontrolled porosimetry(RCP),and scanning electron microscopy(SEM)were used to investigate the PSD of GMZ bentonite,The results indicate that each method has its limitation,and a combined use of PCP and RCP is suitable to obtain the full-scale PSD of GMZ bentonite.Moreover,we also compared the full-scale PSD with nuclear magnetic resonance(NMR)result.It is found that there is no significant difference in the range of PSD characterization between NMR and mercury intrusion method(PCP and RCP).However,in a ce rtain range,the detection accuracy of NMR is higher than that of mercury injection method.Finally,permeability prediction based on PCP and SEM data was conducted,and both of the two methods were found to be able to predict the permeability.The combined method is effective to obtain the full-scale PSD of GMZ bentonite,which is the key to estimation of the sealing ability of bentonite buffer. | Jiangfeng Liu Shuaibing Song Xulou Cao Qingbin Meng Hai Pu Yangguang Wang Jianfeng Liu | 2020 | Journal of Rock Mechanics and Geotechnical Engineering2020，12，2： | 5 |
| 6 | Tectonic Evolution of Southeast Central Asian Orogenic Belt: Evidence from Geochronological Data and Paleontology of the Early Paleozoic Deposits in Inner Mongolia显示文摘In this study, we present detrital zircon U-Pb dating and paleontological data for the newly identified Ayadeng Formation in the northern margin of the North China Block(NCB) and Xibiehe Formation(molasse) in the Bainaimiao arc belt(BAB), which could provide strong evidence indicating the affinity of the BAB and the evolution of the southeast Central Asian orogenic belt(CAOB). Zircon U-Pb data of siltstone samples and paleontological data indicate the Ayadeng Formation dates back to the Early Ordovician. Although its location is near the NCB, its zircon age spectra and paleontology share a closer affinity with those of Tarim and NE Gondwana, as the U-Pb data suggest an age range of 490–2 192 Ma(peak age=629, 788, 965 and 1 935 Ma), and similar gastropod fossils are found in Tarim and NE Gondwana. The U-Pb ages of meta-sandstone samples in the Xuniwusu Formation indicate a shared inheritance with the Ayadeng Formation(before 440 Ma), and the U-Pb ages of sandstone samples in the Xibiehe Formation are concentrated, with age peaks centered at ca. 420 Ma. Fossil corals occur in these two formations, and their age components also indicate a collisional setting. Therefore, it is speculated that the BAB drifted away from Tarim or NE Gondwana during the Ordovician and became attached to northern NCB between 440–420 Ma as an exotic terrane. During the Early Paleozoic, there may have occurred a collision between an arc and a continental block. | Shijie Wang Shichao Li Wenjie Li Zhongyuan Xu Jinfeng Zhang Changhai Li Qiang Shi Yang Liu Wenlong Wang Qingbin Guan | 2020 | Journal of Earth Science2020，31，4： | 4 |

| 8 | Quantitative research of diagenesis:its effect on pore evolution of the Fuyu oil reservoir in the north Qijia region显示文摘From observing cores of 18 wells,identifying 175 ordinary thin sections and 61 thin casting sections,energy spectrum analyses of 37 samples,homogenization temperature measurement of fluid inclusions of 11 samples,we determine the types of diagenesis and pores of the Fuyu oil reservoir in the north Qijia region.We classified the pores and measured their plane porosity using CIA 2000,the software of rock image analysis,calculated the effect of different kinds of diagenesis on porosity,studied the controlling actions of diagenesis to pore evolution quantitatively,combined with burial history,thermal history and their diagenetic environments.Our results show that mechanical compaction and carbonate cementation are the major destructive diagenesed,developed during early diagenesis stages.The reduction in porosity by mechanical compaction and carbonate cementation are about 25% and 8%,while the destructive intensity of siliceous cementation and clay mineral cementation is relatively much smaller,i.e.,the reduction of porosity is about 2% and 0.2% Dissolution is constructive diagenesis,the increment of porosity is about 6%.There are four diagenesis evolution stages,during which the porosity reduced from 30%~38% to 2%~20%.Mechanical compaction and early cementation are the main diageneses in the early diagenesis stages,when porosity was reduced to 2%~10%.Dissolution is the main diagenesis of an A I substage of the middle diagenesis stage,when porosity increased 1%~8%.The dissolution of the A Ⅱ substage of the middle diagenesis stage affected by late cementation,raised porosity 1%~5%.The porosity varied slightly during the middle stage B. | HAO Guoli SHAN Xuanlong LIU Wanzhu WANG Qingbin | 2010 | Mining Science and Technology2010，20，5： | 4 |
| 9 | Anisotropic,Wrinkled,and Crack-Bridging Structure for Ultrasensitive,Highly Selective Multidirectional Strain Sensors显示文摘Flexible multidirectional strain sensors are crucial to accurately determining the complex strain states involved in emerging sensing applications.Although considerable efforts have been made to construct anisotropic structures for improved selective sensing capabilities,existing anisotropic sensors suffer from a trade-off between high sensitivity and high stretchability with acceptable linearity.Here,an ultrasensitive,highly selective multidirectional sensor is developed by rational design of functionally different anisotropic layers.The bilayer sensor consists of an aligned carbon nanotube(CNT)array assembled on top of a periodically wrinkled and cracked CNT-graphene oxide film.The transversely aligned CNT layer bridge the underlying longitudinal microcracks to effectively discourage their propagation even when highly stretched,leading to superior sensitivity with a gauge factor of 287.6 across a broad linear working range of up to 100%strain.The wrinkles generated through a pre-straining/releasing routine in the direction transverse to CNT alignment is responsible for exceptional selectivity of 6.3,to the benefit of accurate detection of loading directions by the multidirectional sensor.This work proposes a unique approach to leveraging the inherent merits of two cross-influential anisotropic structures to resolve the trade-off among sensitivity,selectivity,and stretchability,demonstrating promising applications in full-range,multi-axis human motion detection for wearable electronics and smart robotics. | Heng Zhang Dan Liu Jeng-Hun Lee Haomin Chen Eunyoung Kim Xi Shen Qingbin Zheng Jinglei Yang Jang-Kyo Kim | 2021 | Nano-Micro Letters2021，13，8： | 3 |
| 10 | Impacts of the COVID-19 pandemic on the dairy industry: Lessons from China and the United States and policy implications显示文摘The purposes of this study are to assess the COVID-19 pandemic’s impacts on the dairy industries in China and the United States and to derive policy recommendations for enhancing the diary industries’resilience to pandemics and other market shocks.Specifically,data from the two nations are used to analyze and compare the mechanisms through which the pandemic has affected their dairy industries and to discuss potential lessons from their experiences.The findings suggest that this pandemic has heavily affected the dairy industries in both China and the United States through similar mechanisms,such as decreased farmgate milk prices,disruption and difficulties of moving milk within the supply chains,worker shortages,increased production costs,and lack of operating capital.There were also significant differences in the affecting mechanisms between the two nations,including transportation difficulties from widespread road closures and significant reduction in holiday sales of dairy products in China,and the shutdown of many dairy processors in the United States due to the closing of schools,restaurants,and hotels.While government financial reliefs are highly needed to help many dairy farms and processors survive this pandemic in the short term,the dairy industries and governments need to work together to develop long-term strategies and policies to balance the industries’efficiency and flexibility,product specialization and diversification,supply chain integration and local food systems,and market mechanisms and policy regulations and interventions. | Qingbin WANG LIU Chang-quan ZHAO Yuan-feng Anthony KITSOS Mark CANNELLA WANG Shu-kun HAN Lei | 2020 | Journal of Integrative Agriculture2020，19，12： | 3 |
| 11 | Potential one-step strategy for PET degradation and PHB biosynthesis through co-cultivation of two engineered microorganisms显示文摘The management and recycling of plastic waste is a challenging global issue.Polyethylene terephthalate(PET),one of the most widely used synthetic plastics,can be hydrolyzed by a series of enzymes.However,upcycling the resulting monomers is also a problem.In this study,we designed a co-cultivation system,in which PET degradation was coupled with polyhydroxybutyrate(PHB)production.First,PETase from Ideonalla sakaiensis was expressed in Yarrowia lipolytica Po1f with a signal peptide from lipase.The engineered PETase-producing Y.lipolytica was confirmed to hydrolyze bis(2-hydroxyethyl)terephthalate(BHET)and PET powder into the monomers terephthalate(TPA)and ethylene glycol(EG).Simultaneously,a TPA-degrading Pseudomonas stutzeri strain isolated from PET waste was transformed with a recombinant plasmid containing the phb CAB operon from Ralstonia eutropha,which encodes enzymes for the biosynthesis of PHB.The two co-cultivated engineered microbes could directly hydrolyze BHET to produce the bioplastic PHB in one fermentation step.During this process,5.16 g/L BHET was hydrolyzed in 12 h,and 3.66 wt%PHB(3.54 g/L cell dry weight)accumulated in 54 h.A total of 0.31g/L TPA was produced from the hydrolyzation of PET in 228 h.Although PHB could not be synthesized directly from PET because of the low hydrolyzing efficiency of PETase,this study provides a new strategy for the biodegradation and upcycling of PET waste by artificial microflora. | Pan Liu Tong Zhang Yi Zheng Qingbin Li Tianyuan Su Qingsheng Qi | 2021 | Engineering Microbiology2021，1，1： | 3 |
| 12 | An efficient time-integration method for nonlinear dynamic analysis of solids and structures显示文摘This paper presents an efficient time-integration method for obtaining reliable solutions to the second-order nonlinear dynamic problems in structural engineering. This method employs both the backward-acceleration differentiation formula and the trapezoidal rule, resulting in a self-starting, single step, second-order accurate algorithm. With the same computational effort as the trapezoidal rule, the proposed method remains stable in large deformation and long time range solutions even when the trapezoidal rule fails. Meanwhile, the proposed method has the following characteristics: (1) it is applicable to linear as well as general nonlinear analyses; (2) it does not involve additional variables (e.g. Lagrange multipliers) and artificial parameters; (3) it is a single-solver algorithm at the discrete time points with symmetric effective stiffness matrix and effective load vectors; and (4) it is easy to implement in an existing computational software. Some numerical results indicate that the proposed method is a powerful tool with some notable features for practical nonlinear dynamic analyses. | LIU TianYun LI QingBin ZHAO ChongBin | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，4： | 2 |
| 13 | Convergence History of the Songliao and Jiamusi Blocks in the Eastern End of Central Asian Orogenic Belt: Evidence from Detrital Zircons of Late Paleozoic Sedimentary Rocks显示文摘Central Asian Orogenic Belt(CAOB) is one of the largest accretionary orogenic belts in the world. The eastern segment of CAOB is dominated by Paleozoic Paleo Asian Ocean tectonic regime, Mesozoic Paleo-Pacific tectonic regime and Mongolian-Okhotsk tectonic regime. The Songliao and Jiamusi blocks are located in the easternmost part of the CAOB and are the key region to solve the problem about overprinting processes of multiple tectonic regimes. It is generally believed that the Mudanjiang Ocean between the two blocks was finally closed in the Mesozoic, but the Paleozoic magmatism also developed along the Mudanjiang suture zone, while on both sides of the suture zone, there were comparable Paleozoic strata, indicating that the two blocks had converged during the Paleozoic, and the evolution history of the two blocks in the Late Paleozoic remains controversial. The Carboniferous-Permian terrestrial strata mainly developed in Binxian, Wuchang and Tieli on Songliao Block, Baoqing and Mishan on Jiamusi Block. Samples from the Songliao and Jiamusi blocks in the Late Carboniferous-Early Permian and Late Permian are collected for comparative analysis. The LAICP-MS zircon U-Pb dating results show that the maximum depositional age of Middle Permian Tumenling Formation and Late Permian Hongshan Formation in Songliao Block is ~260 Ma, while that of Tatouhe Formation and Carboniferous strata in Jiamusi Block are ~290 Ma and ~300 Ma, respectively, which supports the previous stratigraphic division scheme. The age peaks of ~290-300 Ma, ~400 Ma, ~500 Ma appeared in the Late Carboniferous to Early Permian strata of Jiamusi Block and the Middle Permian strata of Songliao Block. The age peak of ~500 Ma in the Middle Permian strata of Songliao Block may come from the Cambrian basement, Mashan Complex, of Jiamusi Block, while the age peaks of ~420-440 Ma in the Carboniferous strata of Jiamusi Block may come from the Silurian magmatic arc in Zhangguangcai Range in the eastern margin of Songliao Block, reflects the history that they had been potential sources of each other, indicating that they may have combined in the Paleozoic. The Hongshan Formation of Songliao Block in the Late Permian lacks the age peak of ~500 Ma, which indicate that Jiamusi Block was not the provenance of Songliao Block in the Late Permian, that is, there was a palaeogeographic isolation between the two blocks. Combined with the ~210 Ma bimodal volcanic rocks developed along the Mudanjiang suture zone reported previously, we believe that the oceanic basin between the Songliao and Jiamusi blocks should have been connected in Late Permian and reopened during Late Permian to Late Triassic. | CHEN Zhaoxu LIU Yongjiang GUAN Qingbin | 2019 | Acta Geologica Sinica(English Edition)2019，93，5： | 2 |

| 19 | A new PM_(2.5)-based CADR method to measure air infiltration rate of buildings显示文摘Air infiltration is an important way to exchange indoor air with outdoors.It significantly impacts energy consumption and air quality of buildings.Fine particles(PM_(2.5))in the outdoor atmosphere environment are a potential natural tracer for the measurement of air infiltration rate,especially in the long term field measurement.In this study,a PM_(2.5)-based method,named as CADR(clean air delivery rate)method,is developed to supplement traditional tracer gas method in order to make routine measurement in realistic environments possible and convenient.An air cleaner is installed indoors to reduce indoor PM_(2.5) concentration.Air infiltration is determined by fitting a model to the decreasing concentration data.Comparison with CO_(2) decay method in four different indoor environments gives a normalized mean error of 19%and a correlation coefficient of 0.80 for this method.This justifies the CADR method as a feasible option to measure air infiltration rate.Although subject to several constraints,the proposed method would facilitate field measurement under realistic conditions by being combined with current tracer gas methods. | Cong Liu Siyu Ji Fengjiao Zhou Qingbin Lin Yiqi Chen Xiaoliang Shao | 2021 | Building Simulation2021，14，3： | 1 |
