| 1 | In-situ cosmogenic ^(36)Cl denudation rates of carbonates in Guizhou karst area显示文摘This study quantifies surface denudation of carbonate rocks by the first application of in-situ cosmogenic36Cl in China. Concentrations of natural Cl and in-situ cosmogenic36Cl in bare carbonates from Guizhou karst areas were measured with isotope dilution by accelerator mass spectrometer. The Cl concentration varied from 16 to 206 ppm. The 36Cl concentrations were in range of (0.8-2.4)106 atom g-1 , resulting in total denudation rates of 20-50 mm ka-1 that averaged over a 104-105 a timescale. The 36Cl-denudation rates showed roughly a negative correlation with the local mean temperature. This preliminary observation may suggest the variations of proportions of chemical weathering and physical erosion in denudation process, depending upon local climatic conditions. | XU Sheng LIU CongQiang FREEMAN Stewart LANG YunChao SCHNABEL Christoph TU ChengLong WILCKEN Klaus ZHAO ZhiQi | 2013 | Chinese Science Bulletin2013，58，20： | 7 |
| 2 | Catalytic conversion of lignocellulosic biomass into chemicals and fuels显示文摘In the search of alternative resources to make commodity chemicals and transportation fuels for a low carbon future,lignocellulosic biomass with over 180-billion-ton annual production rate has been identified as a promising feedstock.This review focuses on the state-of-the-art catalytic transformation of lignocellulosic biomass into value-added chemicals and fuels.Following a brief introduction on the structure,major resources and pretreatment methods of lignocellulosic biomass,the catalytic conversion of three main components,i.e.,cellulose,hemicellulose and lignin,into various compounds are comprehensively discussed.Either in separate steps or in one-pot,cellulose and hemicellulose are hydrolyzed into sugars and upgraded into oxygen-containing chemicals such as 5-HMF,furfural,polyols,and organic acids,or even nitrogen-containing chemicals such as amino acids.On the other hand,lignin is first depolymerized into phenols,catechols,guaiacols,aldehydes and ketones,and then further transformed into hydrocarbon fuels,bioplastic precursors and bioactive compounds.The review then introduces the transformations of whole biomass via catalytic gasification,catalytic pyrolysis,as well as emerging strategies.Finally,opportunities,challenges and prospective of woody biomass valorization are highlighted. | Weiping Deng Yunchao Feng Jie Fu Haiwei Guo Yong Guo Buxing Han Zhicheng Jiang Lingzhao Kong Changzhi Li Haichao Liu Phuc T.T.Nguyen Puning Ren Feng Wang Shuai Wang Yanqin Wang Ye Wang Sie Shing Wong Kai Yan Ning Yan Xiaofei Yang Yuanbao Zhang Zhanrong Zhang Xianhai Zeng Hui Zhou | 2023 | Green Energy & Environment2023，8，1： | 6 |
| 3 | Flux of organic carbon burial and carbon emission from a large reservoir: implications for the cleanliness assessment of hydropower显示文摘Accurately quantifying the budget of carbon sources and sinks in hydropower reservoirs is important for evaluating the cleanliness of hydroelectricity. However, current research on carbon emissions from reservoirs has rarely taken into account the organic carbon(OC) buried in sediment. Only greenhouse gas emissions from the water-air interface at reservoirs have been examined, which would result in an overestimation of the greenhouse effect of reservoirs. In November 2017, this study investigated the distribution of sediment in the Hongfeng Reservoir(HFR) in southwest China, a typical large hydropower reservoir, by using an underwater seismology monitoring system. We estimated the flux of OC into sediment using the results of a sediment survey and a dataset compiled from references. Our results show that, the HFR retained 200,715 t of OC in the sediment since its impounding after dam construction to the sampling year of 2017, when the average burial flux was 3,521 t-C aà1(106 g C aà1) and the modern burial flux was 5,449 t-C aà1. After excluding the exogenous OC, the modern valid carbon sink of the sediment was 4,632 t per year. Under the current state of the reservoir, taking the modern valid carbon sink value, the carbon emissions from the reservoir's surface, and the discharge water from the dam into consideration, the net carbon sink of the HFR is found to be 1,098.9 t-C aà1. If the hydroelectricity generated by the reservoir is converted to a carbon sink, then the total net carbon sink becomes 12,972.9 t-C aà1.This work argues that both reservoir sediment and hydroelectricity are important carbon sinks and both should be included in assessments of the greenhouse effects of reservoirs. | Fushun Wang Yunchao Lang Cong-Qiang Liu Yong Qin Ningxiao Yu Baoli Wang | 2019 | Science Bulletin2019，64，9： | 5 |
| 4 | Leaching of dissolved organic matter from seagrass leaf litter and its biogeochemical implications显示文摘Dissolved organic matter(DOM) represents a significant source of nutrients that supports the microbial-based food web in seagrass ecosystems. However, there is little information on how the various fractions of DOM from seagrass leaves contributed to the coastal biogeochemical cycles. To address this gap, we carried out a 30-day laboratory chamber experiment on tropical seagrasses Thalassia hemprichii and Enhalus acoroides. After 30 days of incubation, on average 22% carbon(C), 70% nitrogen(N) and 38% phosphorus(P) of these two species of seagrass leaf litter was released. The average leached dissolved organic carbon(DOC), dissolved organic nitrogen(DON) and dissolved organic phosphorus(DOP) of these two species of seagrass leaf litter accounted for 55%, 95% and 65% of the total C, N and P lost, respectively. In the absence of microbes, about 75% of the total amount of DOC, monosaccharides(MCHO), DON and DOP were quickly released via leaching from both seagrass species in the first 9 days. Subsequently, little DOM was released during the remainder of the experiment. The leaching rates of DOC, DON and DOP were approximately 110, 40 and 0.70 μmol/(g·d). Leaching rates of DOM were attributed to the nonstructural carbohydrates and other labile organic matter within the seagrass leaf. Thalassia hemprichii leached more DOC, DOP and MCHO than E. acoroides. In contrast, E. acoroides leached higher concentrations of DON than T. hemprichii, with the overall leachate also having a higher DON: DOP ratio. These results indicate that there is an overall higher amount of DOM leachate from T. hemprichii than that of E. acoroides that is available to the seagrass ecosystem. According to the logarithmic model for DOM release and the in situ leaf litter production(the Xincun Bay, South China Sea), the seagrass leaf litter of these two seagrass species could release approximately 4×10~3 mol/d DOC, 1.4×10~3 mol/d DON and 25 mol/d DOP into the seawater. In addition to providing readily available nutrients for the microbial food web, the remaining particulate organic matter(POM)from the litter would also enter microbial remineralization processes. What is not remineralized from either DOM or POM fractions has potential to contribute to the permanent carbon stocks. | LIU Songlin JIANG Zhijian ZHOU Chenyuan WU Yunchao ARBI Iman ZHANG Jingping HUANG Xiaoping TREVATHAN-TACKETT Stacey M. | 2018 | Acta Oceanologica Sinica2018，37，8： | 4 |
| 5 | Genomic evidence of lung carcinogenesis associated with coal smoke in Xuanwei area, China显示文摘Xuanwei area, in southwestern China,harbors the highest female lung cancer rate in the country(Supplementary Table 1) [1]. Epidemiological studies have shown that lung cancer incidence in Xuanwei area is associated with the use of different types of local coal for household cooking and heating [2]. The genomic landscape of Xuanwei female adenocarcinoma(XWFA), the most distinctive feature of lung cancer in Xuanwei, has yet to be elucidated systematically. Here,we provide the fundamental resource of genomic datasets for further exploration of XWFA molecular mechanisms and development of targetable therapy. | Honglei Zhang Chao Liu Li Li Xu Feng Qing Wang Jihua Li Shaobin Xu Shuting Wang Qianlu Yang Zhenghai Shen Jinhua Su Xiaosan Su Ruifen Sun Xuhong Zhou Junliang Wang Yongchun Zhou Baowei Jiao Wanbao Ding Xianbao Cao Yue Wang Yunchao Huang Lianhua Ye | 2021 | National Science Review2021，8，12： | 2 |

| 7 | Identification of a potential tumor suppressor gene, UBL3, in non-small cell lung cancer显示文摘Objective: Oncogenes have been shown to be drivers of non-small cell lung cancer(NSCLC), yet the tumor suppressing genes involved in lung carcinogenesis remain to be systematically investigated. This study aimed to identify tumor suppressing ubiquitin pathway genes(UPGs) that were critical to lung tumorigenesis.Methods: The 696 UPGs were silenced by an siRNA screening in NSCLC cells;the potential tumor suppressing UPGs were analyzed, and their clinical significance was investigated.Results: We reported that silencing of 11 UPGs resulted in enhanced proliferation of NSCLC cells, and four UPGs(UBL3, TRIM22, UBE2 G2, and MARCH1) were significantly downregulated in tumor samples compared to that in normal lung tissues and their expression levels were positively associated with overall survival(OS) of NSCLC patients. Among these genes, UBL3 was the most significant one. UBL3 expression was decreased in tumor samples compared to that in paired normal lung tissues in 59/86(68.6%) NSCLCs, was correlated with TNM stage and sex of NSCLC patients, and was significantly higher in non-smoking patients than in smoking patients. Silencing UBL3 accelerated cell proliferation and ectopic expression of UBL3 suppressed NSCLC in vitro and in vivo.Conclusions: These results showed that UBL3 represented a tumor suppressor in NSCLC and may have potential for use in therapeutics and for the prediction of clinical outcome of patients. | Xinchun Zhao Yongchun Zhou Qian Hu Sanhui Gao Jie Liu Hong Yu Yanfei Zhang Guizhen Wang Yunchao Huang Guangbiao Zhou | 2020 | Cancer Biology & Medicine2020，17，1： | 2 |
| 8 | Light-induced variation in environmentally persistent free radicals and the generation of reactive radical species in humic substances显示文摘Environmentally persistent free radicals(EPFRs)in humic substances play an essential role in soil geochemical processes.Light is known to induce EPFRs formation for dissolved organic matter in aquatic environments;however,the impacts of light irradiation on the variation of EPFRs in soil humic substances remain unclear.In this study,humic acid,fulvic acid,and humin were extracted from peat soil and then in situ irradiated using simulated sunlight.Electron paramagnetic resonance spectroscopy results showed that with the increasing irradiation time,the spin densities and g-factors of humic substances rapidly increased during the initial 20 min and then gradually reached a plateau.After irradiation for 2h,the maximum spin density levels were up to 1.63×10^17,2.06×10^17,and 1.77×10^×10^17 spins/g for the humic acid,fulvic acid,and humin,respectively.And the superoxide radicals increased to 1.05×10^l4-1.46×10^14spins/g while the alkyl radicals increased to 0.47×10^14-1.76×10^14 spins/g.The light-induced EPFRs were relatively unstable and readily returned back to their original state under dark and oxic conditions.Significant positive correlations were observed between the concentrations of EPFRs and reactive radical species(R2=0.65-0.98,/?<0.05),which suggested that the newly produced EPFRs contributed to the formation of reactive radical species.Our findings indicate that under the irradiation humic substances are likely to be more toxic and reactive in soil due to the formation of EPFRs. | Yafang Shi Yunchao Dai Ziwen Liu Xiaofeng Nie Song Zhao Chi Zhang Hanzhong Jia | 2020 | Frontiers of Environmental Science & Engineering2020，14，6： | 2 |
| 9 | Identification of a major quantitative trait locus and its candidate underlying genetic variation for rice stigma exsertion rate显示文摘Stigma exsertion in male sterile lines of hybrid rice is important for seed yield.In the present study, ZS616 [Oryza sativa subsp.Xian(indica)], a male sterile line with a stigma exsertion rate(SER) as high as 94.5%, was crossed to DS552, a japonica line with almost no exserted stigmas.F3 plants with extremely low and high SER were sequenced to identify SER-associated quantitative trait loci(QTL).A major QTL for SER, qSER-3.1, was identified along with other QTL on chromosome 3 in a 3.9 Mb region.A total of 307 nonsynonymous single-nucleotide polymorphisms(SNPs) and 27 frame-shift insertion/deletions(InDels)differentiating ZS616 and DS552 were identified in the region containing qSER-3.1.Most SNPs(294) and InDels(25) were excluded after further analysis because they were shared by ZS616 and low(<2.0%) SER accessions in the Huazhong Agricultural University(HAU) core rice collection.Association analysis using the full HAU collection identified a 17-bp InDel in OS03 G0689400 as the most likely causal genetic variant underlying qSER-3.1.ZS616-type accessions(n = 54, with the 17-bp insertion) in the HAU collection had minimum(16.5%)and mean(39.6%) SERs significantly greater than those(n = 424) without the insertion(with minimum and mean SERs of 0.2% and 20.6%, respectively).Thus, this study identified a major QTL for stigma exsertion and revealed the mutation in a candidate gene for the QTL. | Shouling Xu Yunchao Zheng Yang Liu Xiaohao Guo Yuanyuan Tan Qiuping Qian Qingyao Shu Jianzhong Huang | 2019 | The Crop Journal2019，7，3： | 2 |
| 10 | Sulfate sources constrained by sulfur and oxygen isotopic compositions in the upper reaches of the Xijiang River,China显示文摘While it is critical to accurately understand the sources and transformation of sulfate based on time-series analysis, there are limited studies on temporal variation of sulfate in rivers and on rock weathering by sulfuric acids.We conducted a monthly sampling campaign in the Beipan, Nanpan, and Hongshui Rivers over the course of one hydrological year. This study examined seasonal variations in riverine sulfate impacted by the monsoon climate in the upper reaches of the Xijiang River basin. In general, the SO_4^(2-) contents in these rivers dropped from relatively high levels to low values during the high-flow season, in response to increasing discharge. The sulfate was generally enriched in heavy isotopes during the low-flow season compared to the high-flow season. The calculated results indicate that the riverine sulfate was mainly derived from sulfide oxidation, but that evaporite dissolution could be an important source during the low-flow season, based on isotopic evidence. Mine drainage is likely an important source of sulfate to these rivers during the high-flow season due to contributions from fast surface flow, which responds to frequent heavy rain in monsoonal climate regions. Arelatively high proportion of HCO_3^- was found to be derived from rock weathering by sulfuric acid during the high-flow season when compared to that observed during the low-flow season. The results suggest that approximately one quarter of the HCO_3^- in the Hongshui River originated from carbonate weathering by sulfuric acid derived from the oxidation of sulfide. Such information on the specific dual isotopic characteristics of riverine sulfate throughout a hydrological year can provide unique evidence for understanding the temporal variability of sulfate concentrations and weathering processes in rivers. | Jing Liu Siliang Li Jun Zhong Xuetao Zhu Qingjun Guo Yunchao Lang Xiaokun Han | 2017 | Acta Geochimica2017，36，4： | 2 |
| 11 | Hybrid C8-BTBT/In GaAs nanowire heterojunction for artificial photosynaptic transistors显示文摘The emergence of light-tunable synaptic transistors provides opportunities to break through the von Neumann bottleneck and enable neuromorphic computing.Herein,a multifunctional synaptic transistor is constructed by using 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene(C8-BTBT)and indium gallium arsenide(InGaAs)nanowires(NWs)hybrid heterojunction thin film as the active layer.Under illumination,the Type-I C8-BTBT/InGaAs NWs heterojunction would make the dissociated photogenerated excitons more difficult to recombine.The persistent photoconductivity caused by charge trapping can then be used to mimic photosynaptic behaviors,including excitatory postsynaptic current,long/short-term memory and Pavlovian learning.Furthermore,a high classification accuracy of 89.72%can be achieved through the single-layer-perceptron hardware-based neural network built from C8-BTBT/InGaAs NWs synaptic transistors.Thus,this work could provide new insights into the fabrication of high-performance optoelectronic synaptic devices. | Yiling Nie Pengshan Xie Xu Chen Chenxing Jin Wanrong Liu Xiaofang Shi Yunchao Xu Yongyi Peng Johnny C.Ho Jia Sun Junliang Yang | 2022 | Journal of Semiconductors2022，43，11： | 1 |

| 14 | Multiplexed imaging of tumor immune microenvironmental markers in locally advanced or metastatic non-small-cell lung cancer characterizes the features of response to PD-1 blockade plus chemotherapy显示文摘Background:Although programmed cell death 1(PD-1)blockade plus chemotherapy can significantly prolong the progression-free survival(PFS)and overall survival(OS)in first-line settings in patients with driver-negative advanced non-small-cell lung cancer(NSCLC),the predictive biomarkers remain undetermined.Here,we investigated the predictive value of tumor immune microenvironmental marker expression to characterize the response features to PD-1 blockade plus chemotherapy.Methods:Tumor tissue samples at baseline were prospectively collected from 144 locally advanced or metastatic NSCLC patients without driver gene alterations who received camrelizumab plus chemotherapy or chemotherapy alone.Tumor immune microenvironmental markers,including PD-1 ligand(PDL1),CD8,CD68,CD4 and forkhead box P3,were assessed using multiplex immunofluorescence(mIF)assays.Kaplan-Meier curveswere used to determine treatment outcome differences according to their expression status.Mutational profiles were compared between tumors with distinct expression levels of these markers and their combinations.Results:Responders had significantly higher CD8/PD-L1(P=0.015)or CD68/PD-L1 co-expression levels(P=0.021)than non-responders in the camrelizumab plus chemotherapy group,while no difference was observed in the chemotherapy group.Patients with high CD8/PD-L1 or CD68/PD-L1 co-expression level was associated with significantly longer PFS(P=0.002,P=0.024;respectively)and OS(P=0.006,P=0.026;respectively)than those with low co-expression in camrelizumab plus chemotherapy group.When comparing survival in the camrelizumab plus chemotherapy with chemotherapy by CD8/PD-L1 co-expression stratification,significantly better PFS(P=0.003)and OS(P=0.032)were observed in high co-expression subgroups.The predictive value of CD8/PD-L1 and CD68/PD-L1 co-expression remained statistically significant for PFS and OS when adjusting clinicopathological features.Although the prevalence of TP53 or KRAS mutations was similar between patients with and without CD8/PD-L1 or CD68/PD-L1 co-expression,the positive groups had a significantly higher proportion of TP53/KRAS co-mutations than the negative groups(both 13.0%vs.0.0%,P=0.023).Notably,enriched PI3K(P=0.012)and cell cycle pathway(P=0.021)were found in the CD8/PD-L1 co-expression group.Conclusion:Tumor immune microenvironmental marker expression,especially CD8/PD-L1 or CD68/PD-L1 co-expression,was associated with the efficacy of PD-1 blockade plus chemotherapy as first-line treatment in patients with advanced NSCLC. | Fengying Wu Tao Jiang Gongyan Chen Yunchao Huang Jianying Zhou Lizhu Lin Jifeng Feng Zhehai Wang Yongqian Shu Jianhua Shi Yi Hu Qiming Wang Ying Cheng Jianhua Chen Xiaoyan Lin Yongsheng Wang Jianan Huang Jiuwei Cui Lejie Cao Yunpeng Liu Yiping Zhang Yueyin Pan Jun Zhao LiPing Wang Jianhua Chang Qun Chen Xiubao Ren Wei Zhang Yun Fan Zhiyong He Jian Fang Kangsheng Gu Xiaorong Dong Tao Zhang Wei Shi Jianjun Zou Xuejuan Bai Shengxiang Ren Caicun Zhou | 2022 | Cancer Communications2022，42，12： | 1 |

| 16 | Experimental exploration of five-qubit quantum error-correcting code with superconducting qubits显示文摘Quantum error correction is an essential ingredient for universal quantum computing.D espite tremendous experimental efforts in the study of quantum error correction,to date,there has been no demonstration in the realis ation of universal quantum error-correcting code,with the subsequent verification of all key features including the identification of an arbitrary physical error,the capability for transversal manipulation of the logical state and state decoding.To address this challenge,we experimentally realise the [5,1,3]code,the so-called smallest perfect code that permits corrections of generic single-qubit errors.In the experiment,having optimised the encoding circuit,we employ an array of superconducting qubits to realise the [5,1,3] code for several typical logical states including the magic state,an indispensable resource for realising non-Clifford gates.The encoded states are prepared with an average fidelity of 57.1(3)% while with a high fidelity of 98.6(1)% in the code space.Then,the arbitrary single-qubit errors introduced manually are identified by measuring the stabilisers.We further implement logical Pauli operations with a fidelity of 97.2(2)% within the code space.Finally,we realise the decoding circuit and recover the input state with an overall fidelity of 74.5(6)%,in total with 92 gates.Our work demonstrates each key aspect of the [5,1,3] code and verifies the viability of experimental realisation of quantum error-correcting codes with superconducting qubits. | Ming Gong Xiao Yuan Shiyu Wang Yulin Wu Youwei Zhao Chen Zha Shaowei Li Zhen Zhang Qi Zhao Yunchao Liu Futian Liang Jin Lin Yu Xu Hui Deng Hao Rong He Lu Simon C.Benjamin Cheng-Zhi Peng Xiongfeng Ma Yu-Ao Chen Xiaobo Zhu Jian-Wei Pan | 2022 | National Science Review2022，9，1： | 1 |

| 20 | Establishment of Indirect ELISA Diagnosis Technique based on the VP1 Protein of Foot and Mouth Disease Virus Serotype A显示文摘The VP1 protein of foot-and-mouth disease virus serotype A was prokaryotically expressed and purified to replace the traditional virus antigen for establishing a fast,safe,effective indirect ELISA method,so as to detecting antibody of foot-and-mouth disease virus serotype A. Western-Blot test showed that the VP1 recombinant protein could be used as detective antigen as it can be specifically recognized by bovine positive serum of FMDV serotype A. By employing matrix titration method,the optimal parameters were obtained as follows: 1 mg / L VP1 protein as coating antigen,Vserum∶ Vblocking solution = 1∶50 dilution for serum and Vsecondary enzyme-linked antibodies∶Vblocking solution = 1∶2 000 for enzyme combined antibodies. The results showed that the sensitivity and specificity of this method were 94. 32% and 99. 09% respectively,the coefficients of variations in intra-assay and inter-assay reproducibility tests was lower than 8%. Compared with liquid phase blocking ELISA kits,the agreement of 201 serum samples reached 92. 54%. The VP1-ELISA method established here is specific,sensitive,stable and simple,which can be used to monitor the antibody level of FMD serotype A. | Lu Qingxia Liu Chang Jin Qianyue Guo Guanpeng Xing Guangxu Liu Yunchao Deng Ruiguang Zhang Gaiping | 2014 | Animal Husbandry and Feed Science2014，6，6： | 1 |
